An Arid Planet is a planet with environmental conditions similar to those found on the planet Earth but with less water, nearly dry.
A Moonlike Planet is a planet with no atmosphere. Temperatures may therefore vary from very cold to very hot.
An Ice Planet is a type of planet with an icy surface of volatiles such as water, ammonia, and methane. Ice planets consist of a global cryosphere.
A Dwarf Planet is a planetary-mass object that is neither a planet nor a natural satellite. It is massive enough for its gravity to crush itself into a hydrostatic equilibrium shape (usually a spheroid), but has not cleared the neighborhood of other material around its orbit due its low mass.
A Desert Planet is a type of terrestrial planet with very little or no water at all, to distinguish from the Arid planet.
