      I guess is depends on what you say a desert is! If you think of a desert as a place with no liquid rain (like water) then I would probably say Mars or Mercury. Both of those have no actual rain. The gas giants (Jupiter, Uranus, Neptune) all have ‘rain’ but its not H20 water, it’s liquid metals!

      Mars is the biggest planet with little/no atmosphere and has no rain so I would say that it is the largest desert

      Very good question!
