  Cassini: closest-ever view of AtlasApr 17, 2017 9:08 PM PDT | url | discuss | + share
 
Added 1 new A* page:Last month I posted about some close-up new photos the Cassini probe had taken of Saturn's tiny moon Pan, and now we've got even closer-up (within 7,000 miles, whereas it only got within 15,000 of Pan) photos of another small Saturnian moon, Atlas (some confusion as to its size, though: Wikipedia says Pan is 35 km across; it says Atlas is 40 km across, but NASA's article with the photos says Atlas is just "19 miles, or 30 kilometers across"). Like Pan, Atlas has a relatively huge equatorial ridge, probably consisting of material falling onto it from Saturn's rings; Atlas' ridge is smoother than Pan's, though, leaving it more blobby than saucer-like:
