Mars is the fourth planet from the sun. Mars has  two Moons, Phobos and Deimos. They were both discovered in 1877, by Asaph Hall at the Naval Observatory in Washington DC. Phobos is the larger one of Marsâ moons, and it orbits closer to the surface of Mars than Deimos does.
Since the Mars year equals approximately 687 Earth days and a Martian day equals approximately 24.62 earth hours (and, the Earth day equals 24 hours), the math is simple: 687 * 24 / 24.62 = 669.699 ~ 669.7. The Martian year is 669.7 Martian days long. It takes Mars 686.98 days to orbit the Sun. A Mars day is 24.7 hours.
