Mars is the fourth planet of the solar system, the second smallest planet of the system after. Its name comes from the name of the Roman god of war - Mars. It owes it to its colour, which when seen from Earth appears rust-red and was associated with the conflagration of the ancients. In fact, Mars owes its red color to iron oxides, or simply rust. Rustic rocks rich in this metal, just rusted from the top, weathered, and all covered with a layer of rust dust. Underneath, however, it is more familiar - grey. It is a rocky planet.
