Class D planets range in age from 2 to 10 billion years old. Their diameters range in size from 100 to 1,000 km. They are primarily found in orbit of larger bodies or in the asteroid field of the star's solar system. Their surfaces are barren and cratered. The atmosphere within the planet is very tenuous if there is one at all. They are not suitable for life. (Star Trek: Star Charts)
