06 Mars

Mars, the Red Planet, is the fourth planet from our sun and the second smallest planet. Covered by a thin atmosphere, this baron, rocky world is filled with canyons, volcanoes, craters and sand dunes.

NAMING

Because of its red, blood-like color, Mars was named after the Roman god of war.

FUN FACTS

Two polar ice caps expand and contract with the seasons.

 

The orange-red color on the Martian surface is cause by iron oxide, or rust, found in its soil.

 

Mars is home to Olympus Mons, the largest volcano in the solar system, and Valles Marineris, the largest canyon system in our solar system. Valles Marineris stretches over 2,480 miles (4,000 km) wide — that’s about the width of the United States. Its depth of 6 miles (10 km) is five times deeper than the Grand Canyon!
