Dark Material on Planetary Satellites and RingsMaterial of low albedo covers the surfaces, and in some cases constitutes the surfaces, of many planetary satellites. The low mean densities and water ice absorption bands detected in the spectra of some of these bodies show that they are fundamentally icy, but other bodies contain substantial fractions of rocky material. If we define three arbitrary albedo categories ranging from very low to very high, we find that there are many examples in each group.
