Deimos: Mars' moon from 500 km vo2_428b60
Viking 2 Orbiter image of Mars satellite Deimos from a distance of 500 km. Deimos is about 10 km across and north is up. At this distance the surface appears smooth. Many craters are partly hidden by regolith - soil and broken up material. Closer views reveal a heavily cratered surface. Deimos is irregularly shaped and extends about 10 km in its longest dimension.
