Phobos rotation
Webb21 sep. 2024 · Yet Phobos and Deimos not only orbit in the same plane as one another, they orbit within ~1° of Mars’ rotational plane. If these are captured asteroids, it was an almost magical occurrence. http://www.planetary.brown.edu/planetary/geo287/PhobosDeimos/papers/Oberst%20et%20al_The%20Phobos%20geodetic%20control%20point%20network%20and%20rotation%20model-2014.pdf

A rotation parameter that is particularly impor - tant for description of Phobos’ rotation is the amplitude of short period forced libration in longitude (e.g., Bur-meister et al. 2024). Currently, the MOI are not estimated Phobos is the innermost and larger of the two natural satellites of Mars, the other being Deimos.
