Named after the Roman god of war, it is often referred to as the "Red Planet" [1] [2] because the iron oxide prevalent on its surface gives it a reddish appearance. 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.

The variation in Mars's surface water content is strongly coupled to the evolution of its atmosphere and may have been marked by several key stages. Head and others put together a detailed history of water on Mars and presented it in March, 2023. [300] Dry channels near Warrego Valles.
Three of the four solar terrestrial planets (Venus, Earth, and Mars) have substantial atmospheres; all have impact craters and tectonic surface features such as rift valleys and volcanoes. The term inner planet should not be confused with inferior planet , which refers to any planet that is closer to the Sun than the observer's planet is, but ...

Mars is the fourth planet from the Sun.The surface of Mars is orange-red because it is covered in iron(III) oxide dust, giving it the nickname "the Red Planet". [22] [23] Mars is among the brightest objects in Earth's sky, and its high-contrast albedo features have made it a common subject for telescope viewing.
