Mars is about half the diameter of Earth but has a more Earthlike atmosphere than any other planet in the System. The atmosphere is fairly thin and includes clouds and the surface may have small amounts of ice and water. Mars has two moons, Phobos and Deimos, but they are too small to be readily visible at the scale of our Solar System model.
