There are two main categories of '''planets''': [[Terrestrial Planet]]s and [[Gas Giant]]s. Some types of Terrestrial Planets support [[Species|lifeforms]] or meet the conditions for [[terraforming]]. [[Ships]] equipped with the [[Planetary Approach Suite]] may [[Planetary Landings|land on the surface]] of Terrestrial Planets with 0 to tenuous [[Atmosphere|atmospheres]]. Some planets have a [[Planetary Ring System|planetary ring system]]. | There are two main categories of '''planets''': [[Terrestrial Planet]]s and [[Gas Giant]]s.

The term planet refers to a celestial body that orbits a [[star]] with a [[gravity]] in a specific range. The gravity of a planet must be strong enough to hold fluids and plastic solids in a stable state (hydrostatic equilibrium) which prevents them from escaping the planet and it makes the body round, and low enough to prevent stellar nuclear processes to start. | The term planet refers to a celestial body that orbits a [[star]] with a [[gravity]] in a specific range.
