Planets

Planets, often called a worlds, are are celestial bodies that usually orbit a star. Planets often have smaller bodies called moons that would be in orbit around the planet. Many planets are habitable, meaning they are suitable for sentient beings to live on. Planets were generally categorized into three types: terrestrial planets, aquatic planets and gas giants. Although gas giants were generally uninhabitable, floating constructs such as Cloud City could be built if the planet had a habitable layer.

Depending on the tilt of its axis, a planet might have varied seasons with changing temperatures and weather, affecting its habitability. Planets were extremely varied in terms of environmental conditions and landscape, ranging from completely oceanic to thick arboreal rainforests. Some planets, were completely frozen, while other planet are experiencing an ice age. Some planets, are completely barren and desolate, covered in little more than rock and sand; others are an ecumenopolis, in which the entire planetary surface was covered by one gigantic city.
