Mars is the fourth planet from the Sun and the second smallest planet in the Solar System. Named after the Roman god of war, it is often described as the "Red Planet", as the iron oxide prevalent on its surface gives it a reddish appearance. Mars is a terrestrial planet with a thin atmosphere, having surface features reminiscent both of the impact craters of the Moon and the volcanoes, valleys, deserts, and polar ice caps of Earth. The rotational period and seasonal cycles of Mars are likewise similar to those of Earth, as is the tilt that produces the seasons. Mars is the site of Olympus Mons, the second highest known mountain within the Solar System (the tallest on a planet), and of Valles Marineris, one of the largest canyons. The smooth Borealis basin in the northern hemisphere covers 40% of the planet and may be a giant impact feature. Mars has two moons, Phobos and Deimos, which are small and irregularly shaped. These may be captured asteroids, similar to 5261 Eureka, a Martian trojan asteroid.

Famous quotes containing the word mars:

    But in the dome of mighty Mars the red,
    Geoffrey Chaucer (1340?–1400)

    Human beings will be happier—not when they cure cancer or get to Mars or eliminate racial prejudice or flush Lake Erie but when they find ways to inhabit primitive communities again. That’s my utopia.
    Kurt Vonnegut, Jr. (b. 1922)

    What makes the United States government, on the whole, more tolerable—I mean for us lucky white men—is the fact that there is so much less of government with us.... But in Canada you are reminded of the government every day. It parades itself before you. It is not content to be the servant, but will be the master; and every day it goes out to the Plains of Abraham or to the Champs de Mars and exhibits itself and toots.
    Henry David Thoreau (1817–1862)
