As a consequence, the rotational period of Phobos is equal in average to its orbital period.
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. … Webb22 apr. 2024 · But when I took a look at Phobos and calculated the GEO height based on the simple formula for synchronous orbits I got a height that was way above it's L1/L2 …
WebbThe rotational motion of Phobos was first determined in 1981 by Duxbury and Callahan by us- ing Viking orbiter images, which led to dynamical studies of Phobos’ librations …
