Martian satellite orbits and ephemerides

Planetary and Space Science, 2014
Abstract We discuss the general characteristics of the orbits of the Martian satellites, Phobos and Deimos. We provide a concise review of the various descriptions of the orbits by both analytical theories and direct numerical integrations of their equations of motion.
