Desert planet

A desert planet, also known as a dry planet, an arid planet, or a dune planet, is a type of terrestrial planet that is arid at the surface level.

Deserts can be cold or hot, and even retain water, like Antarctica or the Sahara on Earth; however, desert planets are arid across their entire surface. Mars is a prominent example of a (cold) desert planet with a tenuous atmosphere.

But also other arid planets with atmospheres more as well as less dense have been identified as desert planets, like Venus and Mercury.
