An artist's impression of an extrasolar planet

A planet was, in human terms, a celestial body orbiting a star or stellar remnant that was massive enough to be rounded by its own gravity, was not massive enough to cause thermonuclear fusion, and had cleared its neighbouring region of planetesimals.[1]

Types of Planets[]

Earth-like planets[]

Planets formed the main habitat for essentially all lifeforms known to man, and for all the intelligent species known to man. Humans were able to settle on a number of worlds more or less similar to their original homeworld, Earth. In some cases, like Grayson, San Martin, Meyerdahl, or the two Mfecane worlds, a certain degree of genetic manipulation of either the population or the environment was necessary to make the planet in question livable.

Gas giants[]

A gas giant was a large planet that was not primarily composed of rock or other solid matter, like Jupiter in the Sol System, or Uriel in the Yeltsin's Star System. (HH2)
