Mars
Mars is the fourth planet from the Sun and the second-smallest planet in the Solar System. The planet is named after the Roman god of war.
Mars is often called the Red Planet because of the iron oxide present on its surface. It has two moons, Phobos and Deimos. Like Earth, Mars has clouds, winds, a roughly 24-hour day, seasonal weather patterns, polar ice caps, volcanoes, canyons, and other familiar features.
