From EverybodyWiki Bios & Wiki

The fictional universe of the Star Trek canon, which evolved out of the 1966–69 TV series Star Trek, is a vast complex of planets, organizations, and peoples that together comprise an example of the science fiction practice of worldbuilding.

Tagra IV – The dying homeworld of the Tagran species, whose careless industrialization began destroying the atmosphere. On stardate 46192.3, the USS Enterprise-D undertakes a clean up mission of the atmosphere which proves fruitless. However, young intern crewmember Amanda Rogers (who was unknowingly a member of the Q) uses her godlike powers to save the planet.[5]

Commander Riker was accused of murdering the Tanugan physicist Dr. Nel Apgar, who was experimenting on converting Krieger waves and had hoped to sell his Krieger-wave converter to Federation enemies as a weapon; the UFP's interest in the Krieger-wave converter had been primarily as a power source.[20]

Tarakis – Delta Quadrant planet once settled by Nakan colonists. The planet was to be evacuated, but the colonists were instead slaughtered by the rescue forces sent to help them leave. A memorial to the massacre remains on the surface which contains a synaptic generator and causes those who stand near it to receive flashes of images and the intense emotions of the event.[21]

Data was sent to planet since he was immune to the radiation effects.[41]

Terra Nova – also known as Eta Cassiopeia III, was one of the first Earth-colonized planets. Terra Nova was Earth's "great experiment," and was an early human colonization mission, which set its sights on the closest habitable planet from Earth. The world was 20 light-years from Earth, and the early warp drive colony ship heading there took 9 years to reach it.[56] All adults from the original colony were killed after a radioactive asteroid struck the planet. The children survived by going underground and living in caves.

Thasus – Homeworld of the discorporate Thasian species and inhospitable to most other races. The crew of the USS Antares finds a teenage boy named Charles Evans (Robert Walker Jr.) stranded on the planet. The Thasians had granted him psycho-energetic powers for survival, which, because of his lack of maturity and the fact that he was going through adolescence—and its corresponding identity crisis—when they were discovered, proved to be as dangerous as if he had been a child with a fully loaded handgun.[64] Because the Thasians were discorporate, Evans lamented, just before being taken back to Thasus, "I-I can't even TOUCH them!!!"

Thelka IV – Planet from which comes a special dessert Picard wanted to serve to Nella Daren, a Commander he was "dating" for a time aboard the Enterprise.[65]

Tilonus IV – A planet fallen into anarchy that Riker is ordered to infiltrate.[78]

Time Planet – An unnamed planet that had been deserted by an advanced species who created a doughnut-shaped device, a sapient time portal calling itself "The Guardian of Forever," that would transport a being to any place and time they desired. It was first discovered by Captain James Kirk of the USS Enterprise at an unknown stardate in which Dr. Leonard McCoy accidentally stumbled in, sending him to 1930s Earth. They retrieved McCoy, and left the planet with no definite coordinates so that no ship could repeat any accidents.[79] TAS, however, said that in the animated installment "Yesteryear," strictly regulated historical research was conducted there; but when Spock accidentally erased his own existence, he had to use the Guardian of Forever to undo that erasure, and finally contact with the Time Planet was banned altogether.

Titan – Colonized moon of Saturn.[81]

Titus IV – Planet where Miles O'Brien almost stepped on a Lycosa Tarantula. He takes the spider as his pet Christina.[82]

Uxal – Delta Quadrant planet inhabited by a pre-warp civilization. At the turn of the 23rd Century, the first Earth, warp-capable, unmanned probe Friendship 1 landed on Uxal whose inhabitants reverse engineered its technology and developed their own warp drive as well as antimatter weapons. Rival factions on the planet went to war over technology rights until an antimatter bomb was detonated which destroyed the planet's ecosystem. In 2377, the USS Voyager came upon Uxal and helped the remaining survivors to clean up the atmosphere, thus restoring Uxal's environment.[116]
