WebbPhobos and Deimos are in nearly circular orbits above Mars' equator. Both satellites are locked in orbit so that the same side of each constantly faces Mars. This makes their rotational period equal to their orbital period. Both are very dark. They reflect only 3-5% of the sun's light [40, p.167]. WebbPhobos is in synchronous spin-orbit resonance around Mars, like our Moon around the Earth. As a consequence, the rotational period of Phobos is equal in average to its …
