Mars's Fun Facts

Mars's moons Phobos and Deimos go around Mars the opposite way thet most other moons in the Solar System do. Phobos orbits Mars three times a day (Mars day), it is so far the only moon to be discovered that goes around a planet faster than that planet turns. You could launch yourself off Deimos by running, because the escape velocity is only 7 mph (11 km/hr). Phobos is only 6000 km off the surface of Mars, the closest moon to its planet in the Solar System. Mars has the biggest mountain in the Solar System (Olympus Mons).
