A planet (Vulcan)
Planet was the common designation for a certain type of celestial body orbiting a star. They occurred in a great variety of different compositions, masses, and surface conditions. The exact definition of what constituted a planet varied among cultures.
The final appearance of a planet depended on its formation process, which meant where and under what circumstances it formed. Planets could accumulate gigantic atmospheres, exceeding their original size and mass, or they could rest without any atmosphere at all. With a sufficient mass, a planet was able to accumulate so much gas, that it started to undergo nuclear fusion, turning into a protostar. In this state it began to emit energy, as its core temperature and density increased. Planets could also be changed to a Class M environment by terraforming (TNG: "Home Soil").
The Federation had numerous different classifications for planets depending on their mass, composition, surface environment and atmospheric compounds.
Types
Lists
All planets are collected in the category Planets. Additionally, several lists for specific groups of planets exist:
- Cardassian planets
- Dominion planets
- Earth colonies
- Federation colonies
- Federation members
- Homeworlds
- Inhabited planets
- Klingon planets
- Planets in the Delphic Expanse
- Romulan planets
- Uninhabited planets
- Unnamed planets
- Prime planets
- First planets
- Second planets
- Third planets
- Fourth planets
- Fifth planets
- Sixth planets
- Seventh planets
- Eighth planets
- Ninth planets
- Tenth planets
- Twelfth planets
- Fourteenth planets
