NASA's official Instagram account released a photo of Mars Moon 'Phobos,' which resembles a potato. The photograph was shot from a height of 6,800 kilometres (4,225 miles). Phobos, the innermost and largest of Mars' two natural satellites, is larger than Deimos. Both moons were discovered in 1877 by American astronomer Asaph Hall. Phobos is named after the Greek deity of dread and panic, Phobos.
