Mars is the fourth planet from the sun. The volume of mars is 0.15 times the volume of earth. Its density is 3.95 times the density of water. Its mass is 0.11 times the mass of earth. Mars is called the red planet. This cold and dusty planet is covered in red dust. Sometimes the wind whips this up into huge, red sandstorms. In many ways, this is the most similar planet to the earth. It has a thin atmosphere and a day lasts almost the same time as on earth. The sky is pink with a few wispy clouds.
