Deimos - Viking 2 Orbiter
Mars' moon Deimos from 500 km
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.
