Mars: The Red Planet

It is the outermost of the solar system''s small inner planets. The surface is rocky and dusty—the reddish color comes from particles of rust (iron oxide) in the dust. Compare the sizes and order of the planets. Billions of years ago, Mars may have had rivers, lakes, and possibly a large ocean.

Scientists have theorized that during the Solar System''s formation, Mars was created as the result of a random process of run-away accretion of material from the protoplanetary disk that orbited the Sun. Mars has many distinctive chemical features caused by its position in the Solar System. Elements with comparatively low boiling points, such as chlorine, phosphorus, and sulfur, are much more common on Mars than on Earth; these elements were probably pushed outward by the yo
