Mars is the fourth planet from the sun and the second planet nearest the earth after Mercury. It is also the second smallest planet after mercury in our solar system. It is often referred to as mars the Red Planet. When astronauts see it from space found a reddish color outside the mars atmosphere and resulted in red views. Two moons are existing from mars Phobos (FOE-bohs) and Deimos (DEE-mohs). They’re potato-shaped because they have too little mass for gravity to make them spherical.
