Planet

Planets can be divided into types, based on their size, composition, and terrestrial geography.

• Gas Giant - A planet with a small solid core and a large body composed primarily of gases.
  • Ice Giant - A gas giant-like planet consisting of much heavier "ices" rather than the light gases of typical gas giants.
  • Puffy Planet - A planet with an enormous atmosphere but a very low density.
• Chthonian World - A gas giant which has undergone thermodynamic escape, removing it's gaseous outer layers and leaving behind only the planetary core.
• Rocky World - A terrestial planet with a mantle and usually a crust made of rocks or metals.
  • Desert Planet - A Rocky World covered entirely in deserts.
  • Ripe World - A planet with all the necessary conditions for life, but where no native life exists.
  • Primitive World - A planet in which life exits, but native inhabitants have not yet entered a stage at which they are dominant and where they remain basic in anatomy. Sapient life evolving on a primitive world before it can become a garden world is very unlikely.
  • Garden Planet - A planet which has been significantly covered by flora and usually also fauna, the natural evolution of a primitive world. Most species' homeworlds are or at least were Garden Planets at some point.
  • Greenhouse Planet - A planet with a very thick atmosphere that traps in greenhouse gases.
  • Snow Planet - A terrestrial planet covered significantly by snow and ice.
• Ocean World - A planet entirely covered in a single ocean, usually made of water or ammonia.
