... Saturn . ... Saturnт??s rings: less than meets the eye? ... The scientists found that, while the opacity of the B ring varied by a large amount across its width, the mass or amount of material did not vary much from place to place. ... And although this study leaves some uncertainty about the ring s mass, a more precise measurement of the total mass of Saturn s rings is on the way. Previously, Cassini had measured Saturn s gravity field, telling scientists the total mass of Saturn and its rings. ...
