Phobos does not have an atmosphere due to its low mass and low gravity. It is one of the least reflective bodies in the Solar System, with an albedo of about … Visa mer The origin of the Martian moons is still controversial. Phobos and Deimos both have much in common with carbonaceous C-type asteroids, with spectra, albedo, and density very similar to those of C- or D-type asteroids. Based on their similarity, one hypothesis is that … Visa mer Phobos is synchronously orbiting Mars, where the same face stays facing the planet at 6,000 km (3,700 mi) above the Martian surface.
