Mars: The Facts

Mars is the fourth planet from the sun. The average distance from earth to mars is 225 million km, but this number changes constantly because both planets rotate. The climate changes constantly, but it is very cold there, and all water is either frozen or hidden in underground springs. Scientists believe that mars was once warm and wet. Mars has a very thin atmosphere made mostly of Carbon Dioxide. It is also composed of Argon, and Nitrogen. The gravity is 62.5% less than what you'd expirience on earth. The surface areais 144,371,391 km2. Mars has a rocky surface, with many craters, such as the Gale Crater. There are also ancient rivers and mountains.
