Andorian gas giantEdit
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")
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")
Beta Lyrae system planetsEdit
Binary system planetEdit
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.
Blue planet in Klingon spaceEdit
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")
Chin'toka system planetsEdit
Dark matter nebula planetEdit
Deuterium mining colony Edit
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")
Diamagnetic storm planetEdit
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")
Enterprise library computer planetsEdit
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")
According to captain Jonathan Archer, the planet was only a few light years from the red giant which Azati Prime orbited. However, it should be noted that his judgement was severely compromised at the time. (ENT: "Hatchery")
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 planetEdit
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")
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)Edit
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")
Class L planet (2373)Edit
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 sectorEdit
Loque'eque system planetsEdit
Lya Station AlphaEdit
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")
Mericor system planetEdit
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 Edit
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")
Neural parasites planet Edit
Ocean planet systemEdit
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 planetEdit
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")
Pelagic planet Edit
Planet in binary star system Edit
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")
Planet in the Alnitak system Edit
This was an inhabited planet in the Alnitak planetary system. In 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")
Planet in USS John F. Kennedy orders Edit
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")
Planets in USS Albert Einstein ordersEdit
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 survivorsEdit
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 fieldEdit
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")
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")
Pre-warp society planetEdit
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.
Psychotronic stability examination planetEdit
Research Station 75Edit
Ringed gas giantEdit
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")
Rock Creature planetEdit
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")
Romulan minefield planetEdit
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")
Romulan planet Edit
Romulan system planetsEdit
Selcundi Drema planetsEdit
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")
Silaran Prin's planetEdit
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")
Sluggo's adoptive homeworld Edit
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")
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")
Starfleet briefing room planetsEdit
Suliban gas giantEdit
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 homeworldEdit
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.
System J-25 planets Edit
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")
System with shifted orbitsEdit
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")
Takara sector planetEdit
Taurean system planets Edit
The Taurean system was a star system with at least two planets, both unnamed.
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")
Terra Nova system planetsEdit
Tessic's species homeworld Edit
Time planet Edit
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")
Trellium mining planetEdit
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")
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 giantEdit
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 Edit
Vulcan monastery planetEdit
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")
