Deimos in Orbiter

Deimos has been a part of Orbiter since at least the release of Orbiter 2001.

It is a sort of potato shaped body about 16 × 12 × 10 km in size, and is tidally locked so that the same side always faces Mars. It's about 2345 km from Mars in an almost circular orbit, almost circular orbit inclined to the ecliptic about 27°. Escape speed is about 5.6 m/s so that one could almost jump and leave the body. The gravity field at the surface is only about 4% from Deimos, about 3% from the Sun and the remainder from Mars. Its field disappears a bit short of 11 km from the surface.
