Phobos (måne) – Wikipedia

Webb8 mars 2024 · It has been suggested that the two natural orbiting satellites of Mars — the larger inner moon, Phobos, and the smaller outer moon, Deimos — are captured asteroids. While images of these moons taken from spacecraft orbiting Mars have revealed cratered surfaces similar to those seen on typical asteroids, uncertainties about their origin remain. WebbHowever, in the case of Phobos, which is exceptionally close to Mars, its orbital period is much shorter (only about 9 hours) than the planet's rotational period (about 24 hours 37 minutes), so the effects are to a certain extent reversed.
