If you look at Comets...you see many of the similar features...I wonder if Phobos and smaller "moons" are also "captured comets".
Not all ice need be on the surface per se....said of some Comets, and termed more...."Icey Dirtballs", than "dirty snowballs"..."The surface of the nucleus is generally dry, dusty or rocky, suggesting that the ices are hidden beneath a surface crust several metres thick."
Thus a seeming astroidal object, maybe be a comet ONLY when it is close enough to the sun.
I wonder if Phobos is just a captured Asteroid, or such a Comet....
Merry Xmas....one and all,
