 Mars is the fourth planet from the sun in the solar system. The planet is named after the roman god of war, Mars. It is often described as the "Red Planet",﻿ Mars has approximately half the radius of Earth. It is less dense than Earth, having about 15% of Earth's volume and 11% of the mass. Its surface area is only slightly less than the total area of Earth's dry land. While Mars is larger and more massive than Mercury, Mercury has a higher density. This results in the two planets having a nearly identical gravitational pull at the surface that of Mars is stronger by less than 1%. Mars is also roughly intermediate in size, mass, and surface gravity between Earth and Earths moon the Moon is about half the diameter of Mars, where as Earth is twice; the Earth is about nine times more massive than Mars.
