Satellites of Saturn - Optical properties

摘要: Spacecraft and ground-based optical, radio spectrophotometric data on the Saturn satellites are reviewed for clues as to composition microstructures of objects. Minas, Enceladus, Tethys, Dione Rhea have similar photometric phase integrals, with some diversion exhibited by Rhea. Hyperion is nearly same color Iapetus, which displays an overall hemispherical optical asymmetry. Water ice has been observed many small, cratered objects within rings. The frost layers more extensive than those detected Jovian satellites. Titan a methane atmosphere. Finally, Phoebe suspected being captured, asteroidal body.
