Satellite data:
Name: Urania
Orbital period in years: 0.21
Orbital period in days: 77.30
Orbital period in hours: 1855.24
Orbital radius (mean) km: 3.48E+9
Satellite diameter, km: 5502
Surface g, m/s/s: 2.37
Earth gravities: 0.24
Satellite mass, kg: 269.23E+21
Satellite mass, Earths: 0.05
Satellite volume, m^3: 87.21E+18

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.
