Mars is the fourth planet from the Sun. It is nicknamed "the Red Planet" for its orange-red appearance, readily visible from Earth. Mars is a cold rocky desert planet with surface temperatures from −110 °C (−166 °F) to 35 °C (95 °F), and a tenuous carbon dioxide atmosphere, which has an average surface pressure of less than a hundredth of Earth's, making the surface highly exposed to cosmic radiation. On Mars there is no liquid surface water, but water has been found in the atmosphere, forming cirrus clouds, at the polar regions as permafrost and ice caps with seasonal carbon dioxide snow, and in the ground. Its surface gravity is roughly a third of Earth's or double that of the Moon. It is half as wide as Earth, with a diameter of 6,779 km (4,212 mi), and has a surface area the size of all the dry land of Earth.
