Surface and Interior of Small Moons
The small moons are too small to be seen, so their structure can only be guessed. What can be seen indicates the surfaces seem to be covered with craters. Since the density indicates that the composition
of the small moons is mostly ice, there is probably a small core of some rocky material
buried inside, and mantle/overlayers of ice of various kinds
