Mars
An especially serene view of Mars (Tharsis side), a composite of images taken by the Mars Global Surveyor spacecraft in April 1999. The northern polar cap and encircling dark dune field of Vastitas Borealis are visible at the top of the globe. White water-ice clouds surround the most prominent volcanic peaks, including Olympus Mons near the western limb, Alba Patera to its northeast, and the line of Tharsis volcanoes to the southeast. East of the Tharsis rise can be seen the enormous near-equatorial gash that marks the canyon system Valles Marineris.
Mars orbits the Sun at a mean distance of approximately 228 million km (140 million miles). This is about 1.5 times the mean distance of Earth from the Sun, which is approximately 149.6 million km (93 million miles).12
Because Mars has a relatively elongated orbit, its distance from the Sun is not constant; it varies between 206.6 million km and 249.2 million km (128.4 million to 154.8 million miles) throughout its Martian year.1
