Mars is the fourth planet from the Sun and the second-smallest planet in the Solar System, being larger than only Mercury. In English, Mars carries the name of the Roman god of war and is often referred to as the “Red Planet”.[17][18] The latter refers to the effect of the iron oxide prevalent on Mars’s surface, which gives it a striking reddish appearance in the sky.[19] Mars is a terrestrial planet with a thin atmosphere, with surface features such as impact craters, valleys, dunes, and polar ice caps.
