Comments: Urania is the last significant moon in
Aeolus' family of satellites, it is also the largest and has an appreciable
atmosphere. The atmosphere is largely transparent, but fogs and hazes do
sometimes occur which obscure some parts of its surface. The surface is
contrasting with white ice, and dark organic/carbonaceous material, which is the
source of the atmospheric volatiles. The ice surfaces are kept clean by wind,
and a thin precipitation.
