WebAssuming Phobos is made of a mixture of poros- ity (macro-porosity or micro-porosity), Rosenblatt et al. (2011) have proposed models of heterogeneous internal mass distribu- tion inside Phobos, which can fit its bulk density and librational angle. Numerical models suggest that the formation of Stickney Table 1. WebPhobos is the larger of the two moons, and is the closer of the two to Mars. Phobos has an average radius of 11 km, while Deimos has an average radius of 6 km. The origin of Mars' moons, Phobos and Deimos (pictured right), is unknown and remains controversial. One theory is that the moons are captured asteroids.
