Mars

Mars is the fourth planet from our Sun. It is named after the Roman God of war. Mars has two small asteroid-moons, named Phobos and Deimos. (The moons where sucked into the orbit of mars from the nearby Asteroid Belt.)

It's atmosphere is mainly composed of Carbon Dioxide. Most Water-Ice is in the Northern Hemisphere. Most dry ice (Carbon Dioxide-Ice) is in the southern hemisphere. The reason for the red color on the crust is because of iron oxide.
