Unnamed Alpha and Beta Quadrant planets

The following is a list of unnamed planets in the Alpha and Beta Quadrants.

Alnitak planet

This was an inhabited planet circling Alnitak. Circa 2030, a planet in this system was home to a writer who wrote a classic theme to the words, "Let me help." He recommended those words even over "I love you." (TOS: "The City on the Edge of Forever")

Andorian gas giant

This large gas giant was a planet in the Andorian system. The moon Andoria, which served as homeworld of the Andorians, orbited this planet. (ENT: "The Aenar")

According to writers Judith and Garfield Reeves-Stevens in a special features segment in ENT Season 4 DVD, the establishment of the Andorian homeworld as a moon orbiting a gas giant was devised to help explain the contradiction of why it was sometimes called Andor and sometimes it was called Andoria. They explained that it could be both and that they had hoped to establish the gas giant as Andor and the moon as Andoria.

Argo-like planet

Around 2269, a Federation planet "identical" to the planet Argo was expected to undergo seismic disturbances of a similar nature as had transformed Argo. The planet's population was at least in the millions. (TAS: "The Ambergris Element")

Arkonian planet

This blue gas giant planet was in a system annexed by the Arkonians. It was visited by the Enterprise NX-01 in 2152. It had sixty-two moons, at least some of which were partially habitable. Some of the moons' atmospheres were rich in selenium isotopes, which affected the sensor systems of the time. Commander Tucker's shuttlepod crash-landed on one of the moons when an Arkonian patrol ship fired on him. (ENT: "Dawn")

Baran's hide-out

After a short battle with the USS Enterprise-D in orbit of Calder II, mercenary Arctus Baran made a stopover at this planet to repair his ship. (TNG: "Gambit, Part II")

Beta Lyrae system planets

The Beta Lyrae system had at least two planets. (TAS: "The Slaver Weapon")

Binary system planet

This uninhabited planet was more than a hundred light years from Earth and more than twenty light years from the Takret system. It teemed with all sorts of plant and animal life. Its southern continent featured a gorge five times deeper then the Grand Canyon. Due to its binary suns it experienced night only four days a month.

The crew of the Enterprise NX-01 was planning to explore the planet in 2152 when instead they were forced to take shelter in its orbit from a class five neutronic wave front. (ENT: "The Catwalk")

Blue planet in Klingon space

File:Blue Planet With Moons.png

The planet with some moons

This planet, with at least three moons, was part of a system located inside Klingon space. In May 2154, a Bird-of-Prey hijacked by Augments dropped the Denobulan ship Barzai into its upper atmosphere. It became trapped between two thermal layers, forcing Enterprise NX-01 to halt the pursuit of the Bird-of-Prey to rescue the ship and its pilot. (ENT: "The Augments")

From the look the planet might be a gas giant. Given the details of the story, it is probably close to the border of Klingon space, and very close to the path from the border to Qu'Vat colony.

Chakotay's colony

Chakotay's tribe moved to this world near the Cardassian border a few centuries before the 24th century. Kolopak died defending it. (VOY: "Tattoo")[[Link title]]

Chin'toka system planets

The Chin'toka system contained four planets, two of them with a shared orbit were inhabited. (DS9: "Tears of the Prophets")

Dark matter nebula planet

In 2374, Captain Benjamin Sisko and his crew crash-landed a Jem'Hadar attack ship on this planet. (DS9: "Rocks and Shoals")

Deuterium mining colony

Deuterium mining planet — The planet with *Enterprise*

On this planet, members of an alien species built a mobile colony used for mining deuterium. The surface was partly like a desert, rocky, and filled with deuterium fields. Some parts of the hills were filled with some green bushes, trees, and grass. (ENT: "Marauders")

This alien surface was filmed at Ventura County in California.
In the final draft script of "Marauders", five seasons on this planet were equated with "years". The planet as viewed from orbit wasn't physically described, though the script did refer to the colony as consisting "of several modular buildings similar to Quonset huts."

The ENT novel Kobayashi Maru names the planet "Yeq".

Diamagnetic storm planet

The Enterprise NX-01 surveyed a planet containing ruins of an extinct humanoid species in 2152. The ruins consisted of several underground chambers, some of them 4,000 years old. The planet experienced intense diamagnetic storms from time to time. (ENT: "Vanishing Point")

Dominion planet

Damar and his Cardassian Rebellion sabotaged a Jem'Hadar attack ship that exploded while leaving orbit of this planet. (DS9: "Tacking Into the Wind")

Enterprise library computer planets

A number of planets, not further commented upon, were displayed on screens aboard the USS Enterprise-D. (TNG: "The Naked Now", "The Last Outpost", "Hide and Q", "Datalore", "Conspiracy")

Farm planet

This inhabited planet had farms that were tended by automatic machinery as well as a few Humans, which included Eve McHuron and her brothers. Canal mud was an issue. (TOS: "Mudd's Women")

Gas giant

In 2151, the Enterprise NX-01 visited this gas giant planet and found a disabled Klingon Raptor-class ship slowly descending through the layers of the gas giant planet's atmosphere. The crew managed to save the ship just before it buckled under the stress of the extreme pressure of the planet's atmosphere. (ENT: "Sleeping Dogs")

Hatchery planet

This was an uninhabited planet where, in 2154, the crew of Enterprise NX-01 found a derelict Xindi-Insectoid ship located on the surface.

According to Captain Jonathan Archer, the planet was only a few light years from a red giant which Azati Prime orbited. However, it should be noted that his judgement was severely compromised at the time. (ENT: "Hatchery")

Specifically, Archer might be suspected to have wanted to downplay the distance, to justify remaining on the planet longer.
In the final draft script of "Hatchery", this location was initially described as "a small, barren planet."

Iron-silica planet

An iron-silica composition planet was visited by the USS Enterprise in 2267. This planet had an oxygen-hydrogen atmosphere. This uninhabited planet was arid. According to Lazarus, this planet was the homeworld for his species. (TOS: "The Alternative Factor")

Jaradan sector planet

Torona IV remastered — A planet in the Jaradan sector

This planet was the fourth planet in the Torona planetary system in the Jaradan sector.

In 2364 a historic rendezvous between the USS Enterprise-D and the Jarada was held in orbit of this Jaradan sector planet. (TNG: "The Big Goodbye")

This may have been intended to be Torona IV. Please see the note in that entry for more details.

Kantare planet

File:Kantare supply ship (overhead).jpg

A crashed Kantare ship on an unnamed planet (2151)

In 2151, a trader gave Enterprise NX-01 the coordinates of a planet that had an abandoned ship for spare parts, but warned that the ship was haunted. Upon arriving at the unnamed planet, they discovered it was not haunted, but was in fact a ship of holograms (and two living people), that the Kantare supply ship had crashed on, about half way between Kantare and their colony on Kotara Barath. It had at least one moon. (ENT: "Oasis")

Kelvan colony

This unnamed planet was where first contact between the Federation and the Kelvans was made in 2268. The planet's atmosphere was capable of supporting humanoid lifeforms. The planet had one moon. The planet was not too far from the edge of the Milky Way Galaxy, being "within an hour" of the outer barrier - at warp 11.

In that year, a Kelvan ship from the distant Andromeda Galaxy had crash-landed on this planet. Their multi-generational ship had taken only three Earth centuries to cross over from their endangered homeworld Kelva, but could not come through our galaxy's energy barrier intact. The survivors, who had been born in transit and known no other environment, were forced to take shelter here. Sensing a Federation starship was near, they took Human form in anticipation of appropriating the vessel. But they were not yet Human enough to feel comfortable in their surroundings. Rojan called it "this accursed planet" and his lieutenant Hanar said it was "an undisciplined environment." On the other hand, Kelinda did find one of the planet's flowers to be like a Kelvan crystal seen in the record banks of their lost intergalactic ship.

The Kelvans transmitted a distress call which was picked up by the USS Enterprise. A landing party, led by Captain James T. Kirk, made first contact with the Kelvans who subsequently took them captive. After a failed escape attempt, which resulted in the death of Yeoman Leslie Thompson, the Kelvans commandeered the Enterprise for a return trip to the Andromeda Galaxy. After Captain Kirk had convinced the Kelvan leader, Rojan, to release the ship, the Enterprise returned to this planet with the hopes that Rojan and his people could establish a colony for their people. (TOS: "By Any Other Name")

Class L planet (2153)

File:L class planet.jpg

The class L planet

In March 2153, Skalaar and Jonathan Archer set down on this planet to escape Kago-Darr and conduct repairs to Skalaar's Tellarite shuttle. The planet was located less than six light years from Klingon space. (ENT: "Bounty")

In the final draft script of "Bounty", this planet was described as being in a system consisting of "a gas giant and a half-dozen planets." This class L planet was also scripted to have a "murky atmosphere" with "murky, turbulent clouds" which covered the planet. The planet's surface was described as featuring "some rocky outcroppings."

Class L planet (2373)

Class L planet, The ascent — A class L planet

In 2373, Odo and Quark crash landed on this planet. According to Odo, it wasn't much of a planet, and it wasn't much of a sun it orbited. It featured mountainous terrain where only rocks and trees were found there, no slugs, no beetles, no worms, no snails. Its plants appeared to be poisonous. (DS9: "The Ascent")

Class L planet in Rutharian sector

Rutharian sector L class planet — A class L planet in the Rutharian sector

The USS Olympia crashed on this Beta Quadrant L-class planet in the Rutharian sector in 2371, when it was returning from its long-term exploratory mission. (DS9: "The Sound of Her Voice")

Lore's planet

In 2369, Lore and his rogue Borg utilized a base on the surface of this planet. (TNG: "Descent")

Loque'eque system planets

The Delphic Expanse system containing the Loque'eque homeworld also contained several other planets (ENT: "Extinction")

Lya Station Alpha

USS Enterprise-D approaches a Spacedock type station — Lya Station Alpha in orbit of a planet

The planet that Lya Station Alpha orbited in the mid-24th century. This planet had one moon. (TNG: "Ensign Ro")

Magnesite planet

In December of 2154, Enterprise encountered an Orion trader called Harrad-Sar. He invited an away team from Enterprise to beam aboard his ship, where he told Captain Jonathan Archer of a planet rich in magnesite that his vessel had detected. His ship was incapable of removing the magnesite from beneath the planet's surface, so he requested the help of Enterprise. When the starship proceeded to the planet, it was attacked by an Orion ship. Although Harrad-Sar's claim held true – the planet did contain large quantities of magnesite – he later attacked Enterprise and revealed that his plan had always been to disable the NX-class starship. (ENT: "Bound")

Maquis planet

In 2370, Gul Dukat was held captive and tortured on this planet by the Maquis. The Cardassian was later rescued by Commander Benjamin Sisko. (DS9: "The Maquis, Part II")

Mericor system planet

On stardate 45587.9, the USS Denver was hit by a Cardassian gravitic mine while transporting over five hundred colonists. The ship then crash-landed on one of the planets in the Mericor system after it hit the mine. The USS Enterprise-D later responded to the disaster and provided medical assistance to the survivors. (TNG: "Ethics")

Mikulak world

In 2366, the Enterprise-D picked up tissue samples, donated by Mikulak species, on this world. (TNG: "Hollow Pursuits")

Nassuc's homeworld

This planet was part of the empire of the Regent of Palamar, until some time before 2373 his protégé, general Nassuc, a native of this world, founded the Palamarian Freedom Brigade and declared independence. The planet had a population of at least twenty eight million, with seven or eight million concentrated in Nassuc's home city. (DS9: "Business as Usual")

Nassuc's homeworld was not explicitly clarified to be a planet (as opposed to a moon or planetoid).

Neural parasites planet

Prior to stardate 41044.2, this uncharted distant planet was visited by a survey team. During its mission, the team discovered and were subsequently possessed by neural parasites. (TNG: "Conspiracy")

Ocean planet system

After escaping from a Retellian freighter in 2151, Commander Charles "Trip" Tucker and the Kriosian First Monarch Kaitaama set course for a system containing several planets and moons. Only one of the planets turned out to have an atmosphere. It was mostly covered by water, but there was a chain of swampy islands near the equator. (ENT: "Precious Cargo")

Organian observation planet

Enterprise leaves orbit of planet — *Enterprise* in orbit of a planet under Organian observation

This uninhabited class M planet had been under observation by Organians for ten millennia. A deadly silicon-based virus was present on the planet, and the Organians used visitors reaction to the infection as a litmus test to see if visiting species had enough rational intelligence to be ready for first contact.

Among the visitors to the planet who had been infected with the virus were Cardassian and Klingon crews. The Klingons had visited several years before 2154, and had been killed by their own commander in a shuttlecraft, the remains of which still orbited the planet.

In 2154, the Starfleet vessel Enterprise surveyed the planet. They sent four landing parties to the surface, the last of which got infected with the virus. Enterprise left a warning beacon in orbit in order to prevent further infections. (ENT: "Observer Effect")

While leaving the planet, Ensign Sato was seen removing a piece of coral-like plant out of her hair, showing a hint as to the vegetation on the planet.

Pelagic planet

This was an inhabited planet. In 2266, there was an Earth colony of sea ranchers on this world. Ruth Bonaventure hailed from this planet. (TOS: "Mudd's Women")

Planet in binary star system

Painting crusher quarters observation lounge — The planet on a painting

This planet depicted on a painting was located in a binary system.

The painting of this world depicted a fusion-powered landing spacecraft on approach. The painting was displayed at various times in the observation lounge and in quarters aboard the USS Enterprise-D and in a corridor at Starfleet Headquarters. (TNG: "The Naked Now", "Conspiracy", "The Child")

The painting was created by Rick Sternbach for fun. This painting had the greatest number of appearances of paintings done by Sternbach. It was first seen in Beverly Crusher's quarters, later in guest quarters in the episodes "Too Short a Season", "Coming of Age", and "Symbiosis" and in the observation lounge from "The Child" through "Redemption". [1]

Planet in USS John F. Kennedy orders

In 2364, the USS John F. Kennedy received orders from Starfleet operational support services, detailing its patrol duties. These orders were accompanied by several maps and a graphic of a planet. TNG: "Conspiracy")

The graphic was reused from a screen displaying information on the Maxia Zeta system in "The Battle", and may or may not be intended to be the same planet.

Planets in USS Albert Einstein orders

Planetary system library computer 3 — A planetary system

In 2364, the USS Albert Einstein received orders from Starfleet operational support services, detailing its patrol duties. These orders were accompanied a graphic of a planetary system. (TNG: "Conspiracy")

Planets searched for USS Honshu survivors

As part of a search for survivors after the USS Honshu was destroyed in 2374, the USS Defiant visited several planets.

At one planet, two Human survivors were found.

Later the Defiant was in orbit of a Brown planet. From there, it went to the third planet in the same system.

At the very end of the allotted time, one more shuttle was detected, leading the Defiant to yet another planet, where Benjamin Sisko was retrieved. Its day was between 22 and 23 hours in length. (DS9: "Waltz")

Planet within Delphic Expanse anomaly field

File:Harbinger planet.png

The planet

File:Harbinger planet surface.png

The devastated surface of the planet

In an expanding field of Delphic Expanse anomalies, T'Pol located a planet that had once been inhabited, but now had not a single lifeform due to being engulfed in the field some time before December 2153. Its location was within a few hundred million kilometers of a point equidistant to five of the Delphic Expanse spheres. (ENT: "Harbinger")

Based on the diameter of the anomaly of seven hundred million kilometers, and assuming that the rate of expansion of "several" (i.e. at least three) kilometers per second was constant, a quick calculation suggests that the planet was engulfed at the latest about three and a half year before December 2153.

Planet (2267)

This planet was selected by the Metrons for the resolution of a dispute between the Federation and the Gorn. The planet had a suitable atmosphere for both combatants. The planet's surface was populated by scrub bushes, rocks, and mineral deposits. (TOS: "Arena")

Although the Metrons referred to this place as a planet, Captain Kirk once described it as an asteroid.

Planet (2268)

The USS Enterprise picked up Ambassador Kollos, Miranda Jones, and Larry Marvick from this planet. (TOS: "Is There in Truth No Beauty?")

Planet (2368)

After helping treat survivors of the USS Denver and performing an operation on Lieutenant Worf, Doctor Toby Russell was dropped off at this planet by the USS Enterprise-D in 2368. (TNG: "Ethics")

In the script of the episode, the Enterprise-D was in orbit of this planet at the beginning of the episode, too. The planet was identified as Starbase 27. The USS Potemkin transported Doctor Russell to the Enterprise-D while the latter was still in orbit of Starbase 27. In the actual episode, the Enterprise is never seen in orbit of the planet at the beginning of the episode and the starbase is never mentioned; instead, the ships rendezvous in open space. This leaves the possibility that the unnamed planet seen at the end of the episode is Doctor Russell's home base, where the Adelman Neurological Institute was located.

Pre-warp society planet

This planet is home to a pre-warp society with factions in a cold war state.

In 2152 the Enterprise NX-01 visited the planet. Captain Archer and Lieutenant Malcolm Reed were briefly held prisoner here after the authorities discovered a lost communicator and mistook them for enemy infiltrators.

The beverage Allakas malt originates from this planet. (ENT: "The Communicator")

Psychotronic stability examination planet

Psychotronic stability examination 3 — planetary body

This planet or planet-like object was part of Starfleet's psychotronic stability examination. (TNG: "The Schizoid Man")

Research Station 75

The planet where Research Station 75 was located in the mid-24th century. (TNG: "Face of the Enemy")

Ringed gas giant

File:Ringed planet from judgment.png

A ringed planet

A system just outside the border of the Klingon Empire had at least five planets, the fifth of which was a ringed gas giant that was the site of a confrontation between the Earth ship Enterprise and the Klingon battle cruiser IKS Bortas in 2152. the planet featured rings with a typical composition of methane ice, isolytic plasma, and diamagnetic dust. (ENT: "Judgment")

Presumably this planet was also near Raatooras.

Rock Creature planet

The Rock Creature planet was located in an uncharted planetary system. This system was a binary star system. The planet was classified as M-class. The atmospheric pressure on the surface was 800 millibars; gravity was 1.2 times that of Earth, and the average temperature was hot. Though there was no intelligent life on this planet, the planet was inhabited by rock beasts.

In 2269, Harcourt Fenton Mudd with his hostage, Lieutenant Christine Chapel, traveled to this planet. While there, the rock beasts destroyed their transport. The USS Enterprise apprehended Mudd and rescued Chapel. (TAS: "Mudd's Passion")

The name Rock Creature planet is used by Startrek.com.

Romulan minefield planet

In 2152, the Enterprise NX-01 planned to explore an uncharted Minshara class planet. It was uninhabited and its most notable geological feature was a chain of volcanoes spanning an entire hemisphere. After the ship was hit by a mine and two Romulan Birds-of-Prey decloaked, it became clear that the planet was claimed by the Romulan Star Empire. (ENT: "Minefield")

The reference book Star Trek: Federation - The First 150 Years identifies this planet as the third planet in the Unroth system.

Romulan planet

In 2369, the Romulan Warbird IRW Khazara beamed aboard several cargo crates from this planet. The crates contained Vice-proconsul M'ret and two of his aides in stasis. (TNG: "Face of the Enemy")

Romulan system planets

A map of the Romulan star system, featuring two unnamed planets

The innermost and the outermost planet in the Romulan system, containing Romulus and Remus, were depicted on a display graphic. (Star Trek Nemesis)

Selcundi Drema planets

Selcundi drema planet, remastered — Planet in the Selcundi Drema sector

This planet is one of the four uninhabited planets in the Selcundi Drema sector. It is not suitable for colonization due to severe geological activity and is expected end up like Drema V. Several planets were surveyed by the USS Enterprise-D in 2365. (TNG: "Pen Pals")

This planet is presumably Drema I as the depiction fits the mention of Drema I as having "massive volcanic activity".

Silaran Prin's planet

Silaran Prin lived on this planet near the Demilitarized Zone until his death in 2373. (DS9: "The Darkness and the Light")

Sluggo's homeworld

This planet was the homeworld of a species resembling the Earth slug and had an atmosphere that was rich in argon. In 2151, the planet was visited by an away team from the NX-class Enterprise that included Ensign Hoshi Sato, who took one of the planet's slug-like inhabitants, which she named "Sluggo", with her when she returned to Enterprise. (ENT: "Fight or Flight")

Since Sluggo was found before Enterprise traveled to Archer IV (the first M-class planet to be surveyed by the ship's crew), it is reasonable to assume that the creature's homeworld was not an M-class planet. Given that the creature was from a planet with an argon-rich atmosphere, it is possible that its homeworld was a class H planet.

Sluggo's adoptive homeworld

This planet had an argon-rich atmosphere. Ensign Sato and Denobulan Doctor Phlox from Enterprise visited the planet on May 6, 2151 and transplanted a slug-like creature there. (ENT: "Fight or Flight")

Although this planet is shown from orbit in "Fight or Flight" along with the planet's surface also appearing, the episode's script doesn't describe the orbital view of the planet in any detail. The surface is referred to as "a dry, arid landscape, uninhabited" and as a "desert floor" with a "small cluster of rocks."

Starbase planet

This planet was where an unnamed starbase was located. It was located near the Romulan Neutral Zone. In 2269, the USS Enterprise dropped off the survivors of an expedition to Eden at this planet. (TOS: "The Way to Eden")

This planet was remapped for the remastered edition of "The Way to Eden".

Starbase 6

The inhabited planet where Starbase 6 was located. A large space station was located close to this planet in the mid-23rd century. (TOS: "The Immunity Syndrome"; TNG: "The Schizoid Man")

The planet model first used here for Starbase 6 was later used for Acamar III, ("The Vengeance Factor") Ventax II, ("Devil's Due") and Krios. ("The Mind's Eye")

Starbase 11

File:Starbase 11 Planet.jpg

The Enterprise in orbit of Starbase 11

The inhabited planet where Starbase 11 was located in the 2260s. (TOS: "The Menagerie, Part I", "The Menagerie, Part II", "Court Martial")

Starbase 11 was never specifically said to be a planet, and may in fact have been a moon of the large gas giant-like stellar body in its sky.

Starbase 12

The planet was located in the Gamma 400 planetary system, where Starbase 12 was located. (TOS: "Space Seed")

Starbase 73

File:Starbase 73, remastered.jpg

Planet housing Starbase 73

The inhabited planet where Starbase 73 was located. (TNG: "Up The Long Ladder")

The planet model for Starbase 73 was first used for Velara III. ("Home Soil") It was used again for Dytallix B. ("Conspiracy")

Starbase 84

Spacedock type closeup — Starbase 84 in orbit of the planet

The Federation Spacedock-type Starbase 84 orbited this planet in the mid-to-late 24th century. (TNG: "Phantasms")

Starbase 112

The planet where Starbase 112 was located. (TNG: "True Q")

Starbase 133

The Federation Spacedock Starbase 133 orbited this planet in the mid-24th century. The planet had at least one moon. (TNG: "Remember Me")

Starbase 179

The inhabited planet where Starbase 179 was located. (TNG: "A Matter Of Honor")

The planet model for Starbase 179 was first used for Mordan IV. ("Too Short a Season") It was used again for Relva VII. ("Coming of Age")

Starbase 234

The planet where Starbase 234 was located. (TNG: "Redemption II")

Starbase 310

The planet where Starbase 310 was located. (TNG: "Journey's End")

Starbase 416

The planet where Starbase 416 was located. This planet was located near Ogus II. (TNG: "Brothers")

Starbase 515

The world where Starbase 515 was located. The atmosphere was capable of supporting humanoid lifeforms. (TNG: "Samaritan Snare")

Starbase Montgomery

Planet housing Starbase Montgomery

The inhabited planet where Starbase Montgomery was located. (TNG: "The Icarus Factor")

The planet model first used here for Starbase Montgomery was later used for Surata IV, ("Shades of Gray") Angosia III, ("The Hunted") Risa, ("Captain's Holiday") Malcor III, ("First Contact") Starbase 112 planet, ("Identity Crisis") Kaelon II, ("Half a Life") Starbase 234 planet, ("Redemption II") Ruah IV, ("The Chase") Kesprytt III, ("Attached") and Dorvan V. ("Journey's End")

Starfleet briefing room planets

The walls of a meeting room at Starfleet Headquarters on Earth featured a number of photographs or paintings depicting planets and sometimes their moons. (Star Trek VI: The Undiscovered Country)

Suliban gas giant

In 2151, Enterprise encountered a class 7 gas giant while following the warp trail of a Suliban vessel. Under the cyclohexane layer of the planet's atmosphere was an unexpected layer of liquid phosphorus. The planet could be observed to have at least one moon A Suliban helix composed of many Suliban cell ships was located in the planet's atmosphere. Enterprise Captain Jonathan Archer boarded the helix and used a magnetic device to separate the space station. (ENT: "Broken Bow")

Symbiotic lifeform homeworld

File:Vox Sola homeworld.jpg

The surface of the symbiotic lifeform homeworld (2152)

The planet had a moon or a large neighboring planet. In early 2152, after Enterprise had been infected with a symbiotic lifeform, they were able to find the location of its homeworld with the help of the Kreetassans.

Upon finding the planet, an away team went down to return the lifeform, and its severed tendril that Phlox examined, to the larger creature that took up much of the planet. (ENT: "Vox Sola")

System J-25 planets

At least six planets were part of System J-25. One M-class planet was uninhabited and was located seven thousand light years from Federation territory.

Prior to the mid-2360s, this planet was home to a highly industrialized civilization with cities linked by a system of roads. When the Borg attacked, the attacking ships removed cities, which caused rips to appear on the planet’s surface. In 2365, the Federation starship USS Enterprise-D scanned this planet. (TNG: "Q Who")

According to the Star Trek: Star Charts (pp. 13, 81), the system J-25 was located in unexplored space in the Beta Quadrant. This system, also known as FGC-J25, was a single star system. Primary was a Class A star with a magnitude of +5, which was the same brightness as Sol.

According to the script of "Q Who", this is where the firm Borg connection would be made between this episode and the earlier TNG: "The Neutral Zone", "DATA: There is a system of roads on the planet which indicate a highly industrialized civilization. But where there should be cities there are only great rips in the surface. WORF: It is as though some great force just scooped all machine elements off the face of the planet. DATA: It is identical to what happened to the outposts along the Neutral Zone". (Scene 28)

System with shifted orbits

Planet in shifted orbit — Planet undergoing massive volcanic erruptions

This system contained at least three planets. One of them was detected to have undergone an orbital shift by Starfleet, taking it between two gas giants. The gas giants' influence was expected to superheat the core of this planet, covering the planet with erupting volcanos in no time. Enterprise was ordered by Admiral Forrest to study it. While the planet initially appeared lifeless, the seismic activity unearthed subterranean microbes. (ENT: "Horizon")

In the final draft script of "Horizon", multiple lines of ultimately unused dialogue were written about the geologically unstable planet, Malcolm Reed initially remarking that it "Doesn't look particularly interesting," and Charles Tucker III wryly observing, "Glad I don't own property there." Also, the volcanic planet was scripted to be "rugged-looking", whereas the two gas giants were described as "Jupiter-sized planets".

Takara sector planet

This ice-covered world, just outside the Alpha Quadrant, was the crash site of USS Voyager in an alternate timeline. (VOY: "Timeless")

The planet was said to be outside the Alpha Quadrant, but it was close enough to travel to. Therefore we here assume, even if it was not explicitly said, that it was in the Beta Quadrant (as opposed to a Delta Quadrant location.

Taurean system planets

The Taurean system was a star system with at least two planets, both unnamed.

The second planet was chosen as a new homeworld by the Taureans, a warp-capable humanoid species. The alien race settled on the planet when their original homeworld began to die.

The Taureans built for themselves an advanced civilization, including a temple and numerous other architectural wonders. Unfortunately, these new inhabitants did not know at the time that the planet drained humanoid energy. The women's bodies were able to develop a glandular secretion that enabled them to survive and to manipulate certain areas of the males' brains to influence their emotions, ultimately draining the men. This caused the men to weaken and eventually die. The female Taureans realized that, in order to survive, they had to revitalize every 27 years, as they became eternal prisoners of the planet. They were neither capable of aging, dying, or bearing children. They revitalized themselves by means of summoning male crew members of starships from as far as twenty light years away.

In 2269, the USS Enterprise was investigating several disappearances within range of Taurean system when they fell victim to their summons. After reaching an agreement with the Taureans, the crew of the Enterprise arranged for Starfleet to send a ship crewed by women. These women would transport the Taureans to a suitable planet where they could live out their lives as mortal women. (TAS: "The Lorelei Signal")

The novelization of "The Lorelei Signal" depicted this planet as having rainstorms that are "typically sudden."

Terra Nova system planets

File:Terra Nova system.png

Terra Nova system

This system, located less than twenty light years from Earth, contained Terra Nova and several other, unnamed, planets. (ENT: "Terra Nova")

Given how Terra Nova was presented as an uniquely close to home example of a class M planet, it can be suspected that the other planets in the system were not class M.

Tessic's species homeworld

The homeworld of Tessic's species was a planet far away from the planet on which some members established a mining colony. (ENT: "Marauders")

This information was the only information mentioned by Tessic.

Time planet

This unnamed planet was the one where the Guardian of Forever was located.

The planet was littered with the ruins of a massive, forgotten city that stretched beyond the horizon in all directions around the Guardian. Based on initial observations, the ruins appeared to be at least one million years old, although the Guardian claimed to be at least five billion years old, predating the existence of the Sol system.

The planet of the time vortex was discovered by the crew of the USS Enterprise in 2267 and was revisited in 2269 by Captain James T. Kirk and his science officer Spock, accompanied by a team of historians. (TOS: "The City on the Edge of Forever"; TAS: "Yesteryear")

Background information

The planet was not named in the episodes. It was called "the planet of the time vortex" in "Yesteryear". In the reference works, such as Star Trek Maps (p. 30) and The Worlds of the Federation (p. 136), the name "Time planet" was used.

According to the Stellar Cartography: The Starfleet Reference Library ("Federation Historical Highlights, 2161-2385"), the planet was called the Time Vortex Planet (Gateway). It was a quarantined planet in the late 24th century. TVP (Gateway) system was located in the Alpha Quadrant. The primary was a M-class star.

In the originally aired version of "The City on the Edge of Forever", the planet, as viewed from space, was represented with stock footage. However, the same footage was used in many other TOS episodes. For the 2006 "remastered" version of "The City on the Edge of Forever", a new, computer-generated version of the planet was created to replace the stock footage.

The novelization of "Yesteryear" (in Star Trek Log 1) names a city on the time vortex planet as "Oyya." In the novel Imzadi, the planet is referred to in the 25th century as "Forever World", since giving it anything other than such a Guardian-referencing name was felt to have been, in the words of one character, "... like painting a mustache on the face of God." Other Pocket Books novels and Star Trek Online have called the time vortex planet "Gateway," a reference to the Guardian of Forever's final spoken line in "The City on the Edge of Forever", "Let me be your gateway."

Trellium mining planet

The trellium mining planet was located about a six-week journey inside the Delphic Expanse. Trellium-D was mined there. The atmosphere of the planet was extremely polluted; many of the staff wore respirators and sustained survival on the surface was impossible. Members of thirty-one different species worked in the mines in some capacity.

Enterprise visited this planet in September of 2153 because a freighter captain informed them that he had taken a Xindi there some time ago. Upon arrival, Captain Jonathan Archer and Commander Tucker were forced to provide a half-liter of liquefied platinum to the foreman of the north mine to see the Xindi, a Primate named Kessick.

It turned out to be a trap, however. The miners worked by capturing ships and forcing their crew to work as slaves. Enterprise was barely able to escape, but Kessick died in the attempt. (ENT: "The Xindi")

The planet is unnamed in the episode, but the novelization gives it the name of "Blue." The novel Last Full Measure names the planet "Tulaw".

Uninhabited planet

Enterprise had been exploring this planet for three days in March 2153 when they were forced to recall their three surface science teams to pursue a bounty hunter who had captured their captain. They had also put down a number of crewmen on it for shore leave.

Among the planet's most enjoyable regions were equatorial range, including a north summit with an inspiring view. In the north there was the Rykos shoreline, the southern tip of which was 227 kilometers from the polar island chain. These islands featured a pyroclastic debris field, lava tubes, and the hydrothermal pools of Ren-gham. The planet also featured ravines. However, as Skalaar mentioned these things after learning Archer's name, it is possible he made these features up to earn Archer's trust and be able to kidnap him.

The planet supported life, for example a species of marsupials whose saliva was a natural anti-coagulant. There was also an unusual microbe which was capable of inducing pon farr in Vulcans. The microbe was also suspected of being more dangerous to Humans than to Vulcans or Denobulans. (ENT: "Bounty")

Vintaak system gas giant

In the mirror universe, the Vintaak system sported at least one planet, a ringed gas giant with several moons. It was located in Tholian space, and one moon contained a Tholian base. (ENT: "In a Mirror, Darkly")

Volterra Nebula planets

Two unnamed planets were located in the Volterra Nebula, a stellar nursery. In 2369, the USS Enterprise-D visited this nebula for a three-week analysis. (TNG: "The Chase")

Vulcan monastery planet

This planet, between the neighboring Vulcan and Andorian systems, was the site of the P'Jem monastery.

A nearby ringed moon was visible in the sky of the planet.

The planet was known to the Vulcans since at least the early 1st millennium BC. The construction of the monastery at P'Jem, later consecrated to the memory and teachings of Surak, predated the Time of Awakening by over twelve centuries.

By the 22nd century, the Vulcan High Command thought to capitalize on the planet's proximity to the Andorian homeworld by installing a massive long-range sensor array there. The ancient monastery provided cover for this spy station.

Certain Andorian factions remained suspicious even after the peace treaty with the Vulcans. Imperial Guard commandos forcibly searched P'Jem twice before the successful 2151 raid led by Thy'lek Shran. Within a year, the spy station and its ancient cover had been destroyed.

The planet was, perhaps more importantly, the site of the first association of Andorians and Humans, in the persons of Shran and Jonathan Archer. (ENT: "The Andorian Incident", "Shadows of P'Jem") Their grudging partnership played no small part in bringing about the UFP Charter, ten years later. (ENT: "Zero Hour")

In "Shadows of P'Jem", Archer calls P'Jem the "Sanctuary at P'Jem" suggesting that either the area it was in or the planet was also called P'Jem. In the final draft script of ENT: "Desert Crossing", Charles "Trip" Tucker made reference to "that Vulcan monastery on P'Jem," proving the planet was indeed meant to be called "P'Jem". However, this line did not make it on screen. An early non-canonical source for the idea that this planet was called P'Jem was Star Trek Online.

According to Star Trek: Star Charts (p. 45), this planet was located in the Luyten's Star system. It was a stop on the Vulcan trade routes in the 22nd century. P'Jem was located in the Beta Quadrant.

Xindi database planets

Images of several planets appeared in a database captured by Enterprise NX-01. (ENT: "Anomaly")

War games simulation system

In a holographicly simulated tactical scenario played out on USS Voyager in 2371, a red giant system with eight planets, none of them M class, played a minor role. (VOY: "Learning Curve")

The simulation was not explicitly said to be set in the Alpha or Beta quadrant, however the inclusion of Ferengi and Romulan vessels makes this a pretty safe bet.
