== Introduction ==
<div style="width:85%">'''Mars''' is the fourth planet from the Sun and the second-smallest planet in the Solar System after Mercury. In English, '''Mars''' carries a name of the Roman god of war and is often referred to as the '<font color=OrangeRed>Red Planet</font color>'. The latter refers to the effect of the iron oxide prevalent on '''Mars'''' surface, which gives it a reddish appearance distinctive among the astronomical bodies visible to the naked eye. '''Mars''' is a terrestrial planet with a thin atmosphere, having surface features reminiscent both of the impact craters of the Moon and the valleys, deserts, and polar ice caps of Earth.</div>
