Asteroid impact on Mars, computer artwork. Mars is the fourth planet from the Sun. It is scarred by around 43,000 impact craters that have a diameter of over 5 kilometres. There are far fewer craters on Mars compared with the Moon (despite being nearer the asteroid belt) because Mars has a thin carbon dioxide atmosphere, which provides some protection. The orange colour is due to the iron oxides in the rocks.
