From "Clump" to "Moonlet"
|
Caption NASA:"This is a computer simulation of the final stage of the growth of a "clump" in Saturn's Rings. The gravity from a hypothesized moonlet (solid gray sphere in frame center) has collected smaller ring particles (black) to form a temporary aggregation. The particles shown in the simulation are from centimeters to meters (su ch as inches to yards) across. The gray moonlet is 61 meters (200 feet) across".
