Class H
- [planet] A classification for an inhabitable planet rated as desert. These worlds are almost entirely desert; at most they have only 20% of their surface covered in water. Young planets of four to six billion years old tend to be rocky, while those that are older tend to be covered in sand. Life can evolve here, but it is limited; plants tend to be small, as do animals. Weather tends to be dry, with sandstorms and still days with few clouds. Some have snow on their poles and can experience wider variations of weather. They are often incapable of naturally supporting populations above a hundred million humanoid lifeforms. Vulcan is an example Class H world.
