The satellite Cassini has been hovering around Saturn for about three months now. Allegedly a small-scale model for the solar system, the rings are said to be a result of a moon that went to close into Saturn's gravital orbit. This gravital force tore it apart and now the debris and ice orbit it as rings. Recent photos including the first ever photo of Saturn's moon Phoebe show that the moons are in part composed of ice. The rings are wafer-thin, less than 100 metres thick in parts.
