  14. Theories for the origin of Saturn's rings • One theory suggests that the ring particles are leftover debris from the formation of the planet itself. • Another idea is that the rings are debris from a satellite that was unable to form. • Probably the most likely theory is that the particles are the result of an icy satellite that was shattered by an impact with a comet. • A recent proposal by Canup is they are from a differentiated moon, torn apart by tides
