Phobos rotation period
http://www.androidpubs.com/Chap10.htm Webb1 dec. 2012 · Context. Phobos 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 orbital period. The variations of its rotational motion are described by oscillations, called physical librations, which yield information of its interior structure. …
