Alnitak planet Edit
This was an inhabited planet orbiting Alnitak. Circa 2030, a planet in this system was home to a novelist 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")
Ancient humanoid homeworld Edit
Andorian gas giant Edit
This ringed gas giant was a planet in the Andorian system. The moon Andoria, which served as homeworld of the Andorians and the Aenar, orbited this planet, along with at least one other moon. (ENT: "The Aenar")
An arboreal planet near the Denobula Triaxa system was the site where a group of Antarans had once settled. Despite their having left some time ago, some Denobulans, including Phlox's grandmother, believed it to be unclean. Phlox and some friends had been planning a trip there for months, but the week before they left, his grandmother told him he couldn't go due to the Antarans having lived there once. (ENT: "The Breach")
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")
The planet 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. Many of them had an approximate overnight temperature of −10 degrees and a daytime high of 170 degrees.
Badlands gas giant Edit
Badlands planet Edit
Beta Lyrae system planetsEdit
Betazoid colonies Edit
Binary system planet Edit
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 than 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")
Brechtian Cluster planetsEdit
Chin'toka system planetsEdit
A map depicting the layout of the system was displayed aboard Deep Space 9 in 2374, shortly before the First Battle of Chin'toka. The system was subsequently captured and occupied by the Federation Alliance, but fell to a Dominion-Breen counterattack the following year. (DS9: "Tears of the Prophets", "The Changing Face of Evil")
The Chin'toka system fell back into Dominion hands the following year, after a devastating Breen counterattack destroyed all but one of the Alliance's defending starships. (DS9: "The Changing Face of Evil", "When It Rains...")
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 Quark, 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
Class M planet Edit
In 2370, a shuttle carrying Captain Jean-Luc Picard and Voval crash landed on this planet. When Picard detected another structure on the surface, he went to investigate, finding the ruins of a Terellian freighter and one survivor named "Anna". (TNG: "Liaisons")
Cochrane namesakes Edit
The rogue Starfleet ship USS Discovery rendez-voused with a shuttle carrying admiral Katrina Cornwell while orbiting this reddish and barren looking planet with crater-like structures. (DIS: "Project Daedalus")
Crisis planet Edit
In the mid-24th century, during a crisis, Lieutenant William T. Riker's solution was for his ship, the Potemkin, being powered down and holding a position over this planet's magnetic pole, hiding the starship from a foe's sensors. (TNG: "Peak Performance")
Dark matter nebula planetEdit
Denubian Alps planet Edit
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 four thousand years old. The planet experienced intense diamagnetic storms from time to time. (ENT: "Vanishing Point")
Dytallix Mining Company planets Edit
Enterprise library computer planetsEdit
This Federation outpost was defended by Starfleet during a Cardassian border conflict. A brutal engagement, Starfleet and the Cardassians spent weeks killing each other, but Starfleet ultimately secured the outpost, which was considered a major victory.
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")
Genesis sector ringed planet Edit
Gorlan rebel home planetEdit
The Gorlan rebel home planet was an inhabited planet in the mirror universe, which served as a headquarters for the Gorlan uprising against the Terran Empire. The first action of Captain James T. Kirk, after the assassination of Captain Christopher Pike, was the destruction of this planet, resulting in the suppression of the uprising. (TOS: "Mirror, Mirror")
Gorn Hegemony planetEdit
Halee system planetEdit
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")
Holodeck planet Edit
In 2365, Wesley Crusher took Salia on a tour of the Milky Way Galaxy via the holodeck, showing the many places he had visited. This ringed planet was one of the locations seen in that tour. It was orbited by at least two moons. (TNG: "The Dauphin")
Iron-silica planet Edit
An iron-silica composition planet in an unnamed system 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 Edit
This planet was located in the Jaradan sector.
Kaferian apple planet Edit
Kantare planet Edit
In 2151, the alien trader D'Marr gave Enterprise the coordinates of a planet that had an abandoned ship for spare parts, but warned that the ship was haunted. Upon arriving at the 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 halfway between Kantare and their colony on Kotara Barath. It had at least one moon. (ENT: "Oasis")
Kelvan colony planet Edit
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")
Klingon planet Edit
On this Klingon planet, in the late 2260s, trader Cyrano Jones sold tribbles to the Klingons. For selling tribbles and for stealing a glommer from this planet, Jones was accused of ecological sabotage by Captain Koloth and, after escaping from the planet, was pursued by the IKS Devisor. (TAS: "More Tribbles, More Troubles")
Klingon prison planet Edit
In 2258, the Romulan mining vessel Narada from 2387 of the prime reality, commanded by Nero, attacked the Klingon prison planet. It then destroyed an armada of 47 Klingon warbirds. Those on the planet sent an emergency transmission relating the situation, which was picked up and translated by Nyota Uhura in the long range sensor lab at Starfleet Academy. (Star Trek)
Korath's planet Edit
In 2404, Admiral Kathryn Janeway visited this planet to receive the chrono deflector created by Klingon scientist Korath. After Korath initially refused when he expressed interest in SC-4's unusual shield generators, Janeway returned to steal the deflector and traveled back in time to 2378 for the purpose of changing history. (VOY: "Endgame")
L-370 planets Edit
Loque'eque system planets Edit
Lore's planet Edit
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")
Mar Oscura Nebula planetsEdit
The Mar Oscura Nebula contained several class M planets, one of which was briefly visited by the USS Enterprise-D in 2367. Due to malfunctions caused by collisions with dark matter deformations, the planet momentarily disappeared from view upon arrival, and Captain Picard opted to study it from outside the dark matter nebula for safety's sake. (TNG: "In Theory")
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
Minos Korva planet Edit
This planet, located in the Minos Korva system, was a M-class world discovered by the Federation starship USS Exeter on stardate 20483, in the 2340s. It was located in the system's primary habitable zone. At the time of the discovery, it was uninhabited. By 2369, this planet had been colonized by the Federation. (TNG-R: "Chain of Command, Part II")
Nassuc's homeworld 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
After escaping from a Retellian freighter in 2151, Commander 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, consisting of oxygen, nitrogen, and a trace of methane. It was mostly covered by water, but there was a chain of 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
Pergium reactor planets Edit
In 2267, a dozen planets were depedent on the pergium from Janus VI for their reactors. When production fell behind due to the Mother Horta's attacks on the miners, these planets began experiencing reactors shutting down and the failure of their life support systems. (TOS: "The Devil in the Dark")
Phillips' surveys planets Edit
As of 2268, astrobiologist Phillips had surveyed 29 planets that were biologically similar to Alpha Carinae II, making him a good choice for a landing party that would survey Alpha Carinae II, in M-5's opinion. (TOS: "The Ultimate Computer")
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 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")
Planet orbited by Mudd's shipEdit
Planets searched for USS Honshu survivorsEdit
At one planet, two Human survivors were found.
Later the Defiant was in orbit of a brown-hued 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. Captain Jonathan Archer speculated that the alien rescued from the anomaly field was the last survivor. (ENT: "Harbinger")
Planet (2268) Edit
Planets near Crepusculan homeworld Edit
Two planets could be seen from the surface of the Crepusculan homeworld. One of them was smaller or far away. In 2256, Captain Philippa Georgiou and Commander Michael Burnham went through the desert on the Crepusculan homeworld by day and saw the two planets. (DIS: "The Vulcan Hello")
Planets surveyed by Ullians Edit
These eight planets, located in seven star systems, were surveyed by the Ullian telepathic historians in the 2360s. They were collecting a library of memories from the inhabitants. (TNG: "Violations")
Planet used by MetronsEdit
After the Federation and Gorn came into conflict over Cestus III in 2267, the Metrons prepared this planet with a suitable atmosphere for both combatants and transported a Starfleet and Gorn captain there to resolve the dispute.
Psychotronic stability examination planetEdit
Promised planet Edit
The promised planet was the destination of the asteroid ship Yonada, carrying the descendants of those who survived the destruction of their homeworld in 8,000 BC. They were scheduled to arrive at this planet in 2269. (TOS: "For the World is Hollow and I Have Touched the Sky")
Spock visited this remote planet in 2257 after taking leave from USS Enterprise. He was drawn there by the Red Angel, whom he mind melded with and was given a glimpse of the future, which he described as "the end". (DIS: "If Memory Serves")
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, 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
The innermost and the outermost planet in the Romulan system, containing Romulus and Remus, were depicted on a display graphic. This system was located in the Beta Quadrant. (Star Trek Nemesis; PIC: "The End is the Beginning")
Science Station Delta-05 planet Edit
This distant planet was located on the edge of the Romulan Neutral Zone, in Sector 30. In 2364, the Federation outpost Science Station Delta-05 was one of several on both sides of the Neutral Zone that was attacked. Nothing remained. Starfleet initially suspected the Romulans, a theory that was disproved when it became clear that Romulan colonies had been attacked in the same manner. The two powers then decided to share any information they discovered about the incident.
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")
Seven other planetsEdit
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")
Starbase planet Edit
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")
Starbase 12 Edit
The planet where Starbase 12 was located. This Alpha Quadrant world was located in the Gamma 400 star system, in Sector 25712. (TOS: "Space Seed"; TNG: "Aquiel"; DIS: "Magic to Make the Sanest Man Go Mad")
Starfleet briefing room planetsEdit
Strnad solar system planetEdit
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 device to separate the cell ships from the helix. (ENT: "Broken Bow")
Symbiotic lifeform homeworldEdit
System J-25 planets Edit
Prior to the mid-2360s, the sixth 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, noting that the rips were very similar to the scarring detected on several Federation and Romulan outposts along the Romulan Neutral Zone in 2364, which had removed all machine elements on the 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, planet II Edit
The Taurean system, located in a sector unfamiliar (but not untrafficked) to Starfleet, was a star system with at least two planets, both unnamed.
The planet's climate included rain and lightning. Water "accumulations" also existed.
These people 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 females 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 inhabitants, the crew of the Enterprise arranged for Starfleet to send a ship crewed by women. These women would transport them to a suitable planet where they could live out their lives as mortal women. (TAS: "The Lorelei Signal")
Terra Nova system planets Edit
Terran base Edit
This planet was located in the Badlands.
Tessic's species homeworld Edit
Trellium mining planet Edit
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 breathing masks 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
The Vintaak system contained at least one planet, this ringed gas giant with several moons. In the mirror universe, it was located in Tholian space, and one moon contained a Tholian base. (ENT: "In a Mirror, Darkly")
Volterra Nebula planets Edit
Vulcan monastery planet Edit
A nearby ringed moon was visible in the sky of the planet. The surface featured several mountains, many trees and several other plants, canyons and a foggy air. There was also at least one lifeform native to 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 system by installing a secret long range sensor array there. The ancient monastery provided cover for this listening post.
Certain Andorian factions remained suspicious even after the peace treaty with the Vulcans. Andorian Imperial Guard commandos forcibly searched P'Jem twice before the successful June 2151 raid led by Thy'lek Shran. (ENT: "The Andorian Incident")
Background information Edit
In the first draft script of "The Andorian Incident" (which had the working title "Incident at P'Jem"), this planet was called "Kro'el". 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", 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.
The Star Trek Encyclopedia (4th ed., vol. 2, p. 118) identified the planet as "P'Jem". It further stated that the monastery was founded on this class M planet around 800 BCE. Then, in a note to the main entry "P'Jem", the authors said that "it is not entirely clear whether P'Jem was the name of the planet or simply the name of the monastery".
According to Michael and Denise Okuda, the location of P'Jem was ambiguous but they assumed it was close to Vulcan, Andoria, and Earth. ("The Andorian Incident", text commentary, ENT Season 1 DVD special feature)
Non-canon sources naming the planet "P'Jem" include Star Trek Online and the reference book Star Trek: Star Charts. According to the latter source (p. 45), the planet was located in the Luyten's Star system. It was a stop on the Vulcan trade routes in the 22nd century, and was located in the Beta Quadrant.
War games simulation system Edit
Worlds visited by Alidar Jarok Edit
These worlds, numbering over a hundred, were visited by the Romulan Admiral Alidar Jarok during his lifetime. According to him, none of them "possessed the awesome beauty of Romulus". (TNG: "The Defector")
Worlds unaffected by Romulan supernova Edit
After it became clear that the Romulan sun would would go supernova, the Federation devised a plan to relocate nine hundred million Romulan citizens to worlds outside the blast of the supernova. (PIC: "Remembrance")
Xendi Sabu system planetEdit
Xindi database planetsEdit
Zeta Gelis star cluster planet Edit
This planet was located in the Zeta Gelis star cluster and was in orbit of a nearby star. In 2366 the USS Enterprise-D encountered "John Doe" on a crashed escape pod on the planet. (TNG: "Transfigurations")
