Camus II – A planet that once was home to a highly advanced species which, though its people apparently never developed space flight, did manage to develop technology, unknown to the UFP, that enabled two intelligent beings to exchange life-entities. Their ruins have long been studied by Federation scientists. In 2269, a Federation team headed by Dr. Janice Lester and Dr. Arthur Coleman was wiped out by Lester to keep the secret of the life-exchange project. The radioactive element celebium, which emits a unique type of particulate radiation that is deadly to humans, is found in large quantities there; apparently, it is the decay product of an ancient thermo-nuclear war. On star date 42215.2, the Enterprise was on its way to Camus II for an archaeological survey when it was diverted by a distress call."
Canopius Planet – The home of Phineas Tarbolde when he wrote The Nightingale Woman in 1996. On star date 42215.2, the Enterprise was on its way to Camus II for an archaeological survey when it was diverted by a distress call."
Capella IV – The home world of the advanced, yet still tribally governed, Capellan species. Dr. McCoy was stationed on the planet for several years and was familiar with the strict Capellan customs. An ailuroid quadruped whose specimens, possessed of the power to discharge lightning-like bolts of electrical energy powerful enough to kill a humanoid, all hated captivity so much that they always had to be killed within four days of capture, the Capellan power cat, was also described as inhabiting the planet.

Cardassia Prime – The primary home world of the Cardassian species, and the capital of the Cardassian Union. It is the 7th planet in the Cardassian system and is usually referred to simply as "Cardassia." Few people refer to it by its proper nomenclature, "Cardassia VII."
Carema III – The second proposed site of testing experimental particle fountain mining technology.
Carnel – A planet in the midst of a civil war. It was where Capt. Jean-Luc Picard first met Lt. Tasha Yar. Impressed at Yar's heroism in rescuing civilians from a minefield, Picard recruited her to serve aboard the Enterprise-D as head of security.

Celtris III – A Cardassian border planet erroneously thought to have a subterranean development site for metagenic weapons. The "base" was later found to be an elaborate hoax perpetrated specifically to capture Captain Picard himself.
Centauri VII – The immortal Flint possessed some of the works of the artists Taranullus of Centauri VII.
Cerberus II – A planet whose natives had developed a rejuvenation process for the body and shared the secret with Admiral Mark Jameson after he had negotiated a treaty for the planet, only to have him administer an ultimately deadly overdosage of the drugs used in the process to himself.
Cestus III – A Federation colony near the Gorn Hegemony that was attacked by the Gorns in 2267. A powerful alien species of sapient discorporates, intolerant of war, that was known as the Metron Consortium mediated a peace treaty, and now the Federation and the Gorns share the planet equally. In 2371, the colonists formed a baseball league with six teams, including the Cestus Comets and the Pike City Pioneers.
Ceti Alpha V – A then barely habitable planet where, in 2267, Captain James T. Kirk marooned the renegade ruler Khan Noonien Singh and his followers after Khan tried to hijack the Enterprise and murder Kirk. Six months later, Ceti Alpha VI exploded and caused the destruction of Ceti Alpha V's ecosystem, shifting its orbit and rendering it a barren wasteland. At least one native life form survived, the parasitic Ceti eel. The story of Khan's survival is chronicled in the 2006 non-canonical novel, To Reign in Hell: The Exile of Khan Noonien Singh. In 2285, the USS Reliant went to Ceti Alpha V, mistaking it for Ceti Alpha VI, which had been chosen for testing the Genesis Device. Khan stole the ship and set out to avenge himself on Kirk. In addition, years before any of this occurred, in an alternate future in the Star Trek: Enterprise episode "Twilight", after the Xindi destroyed Earth in 2154, the planet became the new homeworld of what was left of Humanity (chosen by episode writer Mike Sussman as a "cruel joke" since the planet would become all but uninhabitable in a hundred years anyway). Note: It is uncertain whether Ceti Alpha is the same as Alpha Ceti, a real star system 220 light years from Earth. Under the Bayer designation system, the Greek letter should precede the constellation name, however, in the novelization of "The Wrath of Khan," Alpha Ceti V is indeed the form used.
Ceti Alpha VI – A sister planet to Ceti Alpha V, and presumably the outermost planet in the system. The planet exploded sometime around 2267 and destroyed Ceti Alpha V's ecosystem by shifting its orbit. The cataclysmic event apparently went unnoticed by the Federation who chose planet VI as the test site for the Genesis Device in 2285. During the survey mission, the USS Reliant goes to Ceti Alpha V by mistake assuming it was sixth planet.
Chalna – The home world of the Chalnoth species, a people who have no laws or organized system of government. Captain Picard visited the planet when he commanded the USS Stargazer.
Chaltok IV – The site of a Romulan research colony nearly destroyed during the test of a polaric ion device, which led to the Polaric Test Ban Treaty of 2268.

Chaya VII – A planet where Enterprise-D designer Dr. Leah Brahms headed up a series of engineering debates.
Cheron – A planet orbiting the star 83 Leonis located within Romulan space, whose civilization wiped themselves out through racial bigotry. The Cheron system, by coincidence, is also the site of the "Battle of Cheron" between the Federation and the Romulans. Considered a "humiliating" defeat by the Romulans, according to Admiral Jarok. It led to the creation of the Romulan Neutral Zone and thus likely climaxed the original Romulan War in 2160.

Picard mentions the incident to Haro, a Bolian Star Fleet cadet he was imprisoned with. When Haro remembers details of the event, of which a first-year cadet would have no knowledge, Picard realizes Haro is not who she claims to be. Cor Caroli is also the name of the star Alpha Canum Venaticorum.
Coridan – Planet in the Chi¹ Orionis star system. At least one homeworld of the Coridan species, which was important in the early development of the Federation for its rich deposits of dilithium and other minerals. Mining rights were a heated debate between the Tellarites and Vulcans. Ambassador Sarek of Vulcan was credited with achieving the consensus toward admitting the planet to the Federation. In 2374, Coridan's dilthium mines were attacked by the Dominion.

Delta Vega – A remote, uninhabited planet, near the edge of the galaxy and site of an abandoned lithium cracking facility, where Captain Kirk attempted to maroon Lt. Cmdr. Gary Mitchell after he developed dangerous psychic powers and threatened the Enterprise. A planet called Delta Vega also appears in the 2009 Star Trek movie. Both the elder Spock and Kirk are marooned there in an arctic region. Spock was left on the planet by the Romulan Nero so he could watch his home world of Vulcan be destroyed. Here, Vulcan and Delta Vega appear close to each other and are possibly in the same star system. (However, according to the semi-canon book Star Trek Star Charts by Geoffrey Mandel, Vulcan is in the 40 Eridani A system which does not include Delta Vega.) After Kirk disrupts the Enterprise mission, he is marooned on Delta Vega by the younger Spock on star date 2252.48. Kirk eventually encounters the older Spock and the two find Montgomery Scott working in a Federation research facility on the planet. Star Trek writers Alex Kurtzman and Roberto Orci, however, have stated that, while the similar name is intentional, the Delta Vega in the episode and the film are not the same planet.

Commander Data was contacted by a young Dreman girl named Sarjenka asking for help. He went against orders and the Prime Directive and went to the surface to help her. Later, Wesley Crusher came up with the idea of launching probes onto the surface that would emit harmonic vibrations that could quell the tectonic stresses at the core.

Earth – Also known as Terra, or Sol III. Earth is the homeworld of the Human species, and the location of the capital of the United Federation of Planets in Paris, as well as Starfleet Headquarters based in San Francisco. Residents of Earth were called Terrans in the alternate "Mirror" universe. Earth's moon, called Luna, or Sol IIIa, is also colonized. The capital is Tycho City. At least one other sentient race evolved on Earth in the past, the reptilian Voth species. Possibly descended from Hadrosaurids, the Voth became advanced and developed space travel, escaping Earth before an asteroid impact 65 million years ago. They relocated to the Delta Quadrant. Another likely-sentient race evolved on Earth along with Humans, as humpback whales are strongly implied to be sentient based on their communication with Spock and the probe orbiting Earth in Star Trek IV.
Eden – A planet sought by the mad Dr. Sevrin and his group of young followers. They believed the planet lay in the Romulan Neutral Zone and forced the Enterprise NCC-1701 to go there.

Ekos – The "inner" planet of its system whose inhabitants, the Ekosians, modeled their society after Nazi controlled Germany of mid-20th Century Earth, This was implemented by a Human observer, the historian Professor Dr. John Gill, Ph.D., who believed that, under a benevolent Führer (himself), what he wrongly perceived as the regime's order and efficiency could be achieved without its brutality. This contaminated the development of the planet's culture, and after the Ekosian Melakon, a power-hungry leader more in line with the "real" Nazis, secretly took control and made Gill his puppet, Ekos declared war on the "outer" planet of Zeon.
Elas – A planet whose people sought peace with a warring neighbor world, Troyius, with an arranged marriage. The tears of Elasian females have an aphrodisiac affect on men, apparently through an infectious microbe that Elasian women carry with no apparent effect on themselves. Scott tells the story of transporting the Dohlman of Elas.
El-Adrel IV – A planet where a dimensional-shifting creature resides. In 2368, a Tamarian captain named Dathon took Picard there, against the latter's will, to fight the beast together. Dathon's attempts at intelligent communication and cooperation were hampered by the Tamarian language structure, which consisted of cultural metaphor and allegory, but Dathon hoped that a common, shared danger against which the two captains might have to join forces could help his people, "The Children Of Tama," and the Federation reach a non-aggression pact. That commitment proved to be one for which he was willing to give his life, and indeed, he so gave it and thus became a martyr for the cause.
El-Auria – The home of the El-Aurian species, which was destroyed by the Borg. In 2293, two El-Aurian refugee ships were caught in the Nexus Energy Ribbon. Guinan was among those rescued from one of the ships before it was destroyed.

^Contrary to what Professor Dr. Gill perceived, Nazi government, in reality, was actually a notoriously inefficient government; almost no two Nazi officials considered each other friends, their jurisdictions were semi-autonomous and more often than not overlapped and/or collided, and virtually none were truly selfless in their ambitions – in reality, Hitler to a great degree intended his government to be inefficient, as the animosities among his subordinates made it unlikely that they would band together and thereby threaten his power.
