Mars je čtvrtá planeta sluneční soustavy, druhá nejmenší planeta soustavy po Merkuru. Je pojmenována po římském bohu války Martovi. Jedná se o planetu terestrického typu, tj. má pevný horninový povrch pokrytý impaktními krátery, vysokými sopkami, hlubokými kaňony a dalšími útvary. Kolem ní obíhají dva malé měsíce nepravidelného tvaru pojmenované Phobos a Deimos.

Mars Hubble.jpg
NASA's Hubble Space Telescope took the picture of Mars on June 26, 2001, when Mars was approximately 68 million kilometers (43 million miles) from Earth — the closest Mars has ever been to Earth since 1988. Hubble can see details as small as 16 kilometers (10 miles) across. The colors have been carefully balanced to give a realistic view of Mars' hues as they might appear through a telescope. Especially striking is the large amount of seasonal dust storm activity seen in this image. One large storm system is churning high above the northern polar cap (top of image), and a smaller dust storm cloud can be seen nearby. Another large dust storm is spilling out of the giant Hellas impact basin in the Southern Hemisphere (lower right).
