This is what Mars would look like from its moon Phobos (Illustration)

Phobos is the larger of Mars' two moons and is 17 x 14 x 11 miles (27 by 22 by 18 kilometers) in diameter. Phobos was discovered on Aug. 17, 1877 by Asaph Hall. It orbits Mars three times a day, and is so close to the planet's surface that in some locations on Mars it cannot always be seen.

Phobos is nearing Mars at a rate of six feet (1.8 meters) every hundred years; at that rate, it will either crash into Mars in 50 million years or break up into a ring. Its most prominent feature is the 6-mile (9.7 kilometer) crater Stickney, its impact causing streak patterns across the moon's surface. Stickney was seen by Mars Global Surveyor to be filled with fine dust, with evidence of boulders sliding down its sloped surface.

Asaph Hall named Mars' moons for the mythological sons of Ares, the Greek counterpart of the Roman god, Mars. Phobos, whose name means fear is the brother of Deimos.
