Dwarf
Class D or Dwarf planets are small worlds, only about one hundred to four thousand kilometers in diameter. These worlds are typically dominated by craters, but are otherwise barren. Dwarf planets are relatively old, between two to ten billion years old. Class D objects are composed primarily of rock and ice, however there composition is heavily dependant on the location within the system. Objects in this class can exist within any region of a star system, between the hot zone to the cold zone. Because of their low mass, some dwarfs have very tenuous atmospheres, while many completely lack one. Although not unheard of, Class D objects rarely poses life and are unsuitable for humanoid life, the environment can be adapted with pressure domes. Most Class D objects are Moons of other planets, comets, Dwarf planets, and asteroids.
