The Phobos is made of carbonaceous chondrites. It is irregularly shaped and is the innermost and largest of the two satellites of moon. Also, due to its irregular surfaces, its Albedo is one of the least in the solar system. Albedo is the measure of solar radiation diffusion. Phobos does not have an atmosphere due to its low mass and gravity.
