  Cassini sees tiny Pan's giant ridgeMar 13, 2017 9:48 PM PDT | url | discuss | + share
 
Added 1 new A* page:NASA's Cassini probe is getting some great stuff in its last sweeps through the Saturnian system; it just passed within 25,000 km of the tiny, 35-km-wide inner moon Pan and found the moon's shape dominated by a massive equatorial ridge:

^ More photos of the strangely shaped moon on the Jet Propulsion Laboratory's site at that "source" link. : ) The equatorial ridge forms when material from Saturn's nearby rings falls onto the moon as it sweeps past them. Such ridges are not unusual among Saturn's moons: Atlas and the much larger Iapetus have them, for instance.
 
Thanks to my brother for tipping me off to the new Pan photos. : )
