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

892-IV moons Edit

892-IV, remastered

892-IV and two moons

The planet 892-IV was observed to have two moon-like objects nearby. (TOS-R: "Bread and Circuses")

These bodies could only be seen in the remastered version of the episode.

Andevian II moons Edit

This planet had at least four moons. In 2369, Lwaxana Troi had a holo-program of dawn on this moon. She had reserved with Quark a suite for her and Odo where they would experience dawn on this moon while sharing a picnic. (DS9: "The Forsaken")

Archer IV moons Edit

Archer IV moons

Two moons in the Archer IV sky

Archer IV was observed to have at least two moons. (ENT: "Strange New World")

Argolis Cluster moon Edit

Argolis Cluster moon

A moon in the Argolis Cluster

In 2368, the USS Enterprise-D conducted a survey of the Argolis Cluster's star systems as a possible prelude to Federation colonization. During the survey, it discovered a crashed Borg scout ship on the moon of the fourth planet of one of the six star systems in the Argolis Cluster with one surviving drone, who would later be known as Hugh. (TNG: "I Borg")

Andorian system moons Edit

The large gas giant like body near Andoria had at least one other body associated with it. (ENT: "The Aenar")

One of the Andorian moons had a Preserver obelisk. Michael Burnham saw this world during a 2256 demonstration of the experimental spore drive. (DIS: "Context Is for Kings")

Arkonian planet's moons Edit

Arkonian planet

Arkonian gas giant and three of its moons

An unnamed gas giant annexed by the Arkonians had 62 moons, some of which were partially habitable. (ENT: "Dawn")

To portray the progressively hot surface of one of these moons, the set was made very bright but not hot. "It's a big room but they were only lighting a specific spot," explained Tucker actor Connor Trinneer. (Star Trek Monthly issue 110, p. 20)

Azati Prime system moonsEdit

The system containing the planet Azati Prime had several lunar outposts and at least two moons. The planet was observed to have one moon-like object nearby.

Furthermore, the planetoid further out in the system also had a moon, which contained a monitoring station manned by three Xindi. (ENT: "Azati Prime")

Given the way the moon was brought up without explanation very abruptly and its surface had a similar texture as the planetoid Enterprise had been shown orbiting earlier, a Homeric nod might be suspected, the writers mistakenly referring to the same body both as a planetoid and later as a moon.

Bajor moons Edit

Aside from Derna and Jeraddo, Bajor had at least three more moons. (DS9: "The Nagus", "Progress")

Bajor VII third moon Edit

In 2370, a shuttlepod was lost somewhere in the vicinity of this moon of Bajor VII. (DS9: "Whispers")

Bajor VIII second moon Edit

Bajor VIII second moon

The second moon of Bajor VIII

In 2369, Bajoran terrorist Tahna Los, aboard the runabout USS Yangtzee Kiang, rendezvoused with Lursa and B'Etor's Bird-of-Prey near the lower moon of Bajor VIII to receive a quantity of bilitrium explosive. The USS Ganges, monitoring the exchange from behind the second moon, attempted to intercept him, but Tahna threatened to detonate the bomb in low orbit and wipe out the colonies on the surface. The Ganges was forced to allow him to head towards the Bajoran wormhole. (DS9: "Past Prologue")

Barkon IV moon Edit

This moon orbited a gas giant in the Badlands. In 2371, Major Kira Nerys and Odo landed on this moon to search for a crash-landed Peregrine-class courier ship. (DS9: "Heart of Stone")

According to, this moon was classified as M-class.

Golana moonsEdit

Golana landscape with moons

A picture of a Golana landscape with two moons

Golana was depicted as having two moons. (DS9: "Time's Orphan")

The moons were not seen in the outdoor scenes in the episode, but rather in three different pictures of the planet created by Molly.

Moons of GrazerEdit

RigelVII-Holberg917G fortress

The reuse of Rigel VII's fortress

In the original version of the episode, Flint's home was depicted by a re-used matte painting of a Kalar castle on Rigel VII from "The Cage". According to
Star Trek Maps (p. 28, chart D), Holberg 917G was the seventh planet in the system, and had once supported a neanderthaloid population similar to the Kalar. The single moon of the planet seen in the original version of the episode was named Tanisse.

Jupiter moonsEdit

The planet Jupiter had many moons, including Io and Ganymede.

After The Doctor transferred himself from the Delta Quadrant to Jupiter Station to treat Doctor Lewis Zimmerman for an ailment, the ungrateful Dr. Zimmerman congratulated him and recommended that during his visit he tour "Jupiter's third moon," noting that he heard the lava flows on it were lovely during that particular time of year. (VOY: "Life Line")

Zimmerman's statement is somewhat unclear. He may have been referring to Ganymede, the third Galilean moon, rather than Amalthea, Jupiter's actual third moon, although Io (Jupiter's first moon) is the only (currently known) moon of Jupiter to display active volcanism. It's possible his statement was not meant to convey any actual information.

This moon featured in the Ktarian moonrise simulation, a holoprogram. (VOY: "Revulsion")

Mab-Bu VI moon Edit

Mab-Bu IV - Moon

The planet and its moon

Mab-Bu VI moon surface

Moon surface

The gas giant Mab-Bu VI had one unnamed moon. The moon could only barely be considered class M and was constantly swept by ionic cyclones and electromagnetic storms. The ground cover was all non-porous rock which made a survival for a long time on the moon very unlikely.

During the 19th century, hundreds of convicted criminals from Ux-Mal were imprisoned on the moon, their consciousnesses detached from their physical bodies and set adrift in the moon's constant storms.

In 2167, the criminals attempted to escape aboard the Federation starship USS Essex. However, the starship became trapped in the electromagnetic currents in the moon's atmosphere and was destroyed.

The criminals tried to escape again in 2368, when the USS Enterprise-D arrived to investigate the distress call from the Essex. They inhabited the bodies of Data, Deanna Troi, and Miles O'Brien, claiming to be the disembodied minds of Essex crew members. They took the ship under their control and ordered to assume a polar orbit of the southern polar region, where the other members of their species were located. Their true identities were uncovered and the criminals were expelled before they could bring aboard the rest of their number. (TNG: "Power Play")

Matalas Prime moonsEdit

Matalas Prime had several ringed moons. (ENT: "Dawn")

Maxia Zeta IV Edit

The Maxia Zeta system was known to have at least two moons. (TNG: "The Battle")

This was not stated or shown, but comes from the captain's log entries of the USS Stargazer seen in the episode.

Nimbus III moons Edit


Nimbus and moons

Nimbus III could be observed to have at least two moons. (Star Trek V: The Final Frontier)

Omicron Theta moons Edit

Omicron Theta had at least two moons. (TNG: "Datalore")

Pentarus III moon Edit

A moon of Pentarus III

Next to Lambda Paz, Pentarus III had at least one more moon. (TNG: "Final Mission")

Pernaia Prime moon Edit

Landing pad pernaia prime

An outpost on Pernaia Prime's moon

Pernaia Prime had a single frozen but life-supporting moon. It was about one hundred light years from Earth. In 2152, the moon supported a settlement. (ENT: "The Seventh")

In the final draft script of "The Seventh", this moon was described as "a small, irregularly-shaped moon with a dense atmosphere."

Rigel VII moon Edit

RigelVII-Holberg917G fortress

Rigel VII sky

In the sky of Rigel VII, two bodies could be seen. The song "Moon over Rigel VII" seemed to imply that at least one of them was a moon. The other body, more distant than the moon, was another planet in the Rigel System. (TOS: "The Cage", "The Menagerie, Part II"; Star Trek V: The Final Frontier)

Risa moonsEdit

Risa was known to have at least two moons. (ENT: "Two Days and Two Nights")

A deleted scene from "Fallen Hero" established that there were three.

Romulus or Remus moon(s) Edit

Either Romulus or Remus seems to have had at least one moon.

The map of the Romulan system seen in Star Trek Nemesis does not depict moons around any of its four planets. However, TNG: "The Defector" has a scene showing two bodies in the Romulan sky, one of which might be Remus, which would make the other a moon of either Romulus or Remus. Alternatively, both might be moons. ENT: "The Aenar" also shows an object close to Romulus, the texture of which doesn't seem to correspond with Remus. The final draft script of "The Aenar" identified it as a Romulan moon. Note that despite the perspective, this body could be quite small.

Saturn moons Edit

Stock footage of the same moon was used in DS9: "Treachery, Faith and the Great River" to show Gul Russol's moon. It is possible that both moons represent the same moon and that Gul Russol is indeed Odo's informant.

Small barren moon (2375)Edit

Small barren moon, Treachery, faith and the great river

A small moon

In 2375, Odo wanted to meet one of his Cardassian informants, Gul Russol on this small moon. Instead, he found the defecting Weyoun 6. (DS9: "Treachery, Faith and the Great River")

Around 2151, a revolt led by Captain Jonathan Archer allowed all eighty-nine Suliban prisoners at the complex to escape. (ENT: "Detained")

The Tandaran moon was described, in the final draft script of "Detained", as being twenty hours' travel time from the edge of Tandaran space.
Visually, the Tandaran moon was a reuse of a planet from ENT: "Fight or Flight".
