Early in 2017, as Cassini began to circle the drain on its Saturn orbits, it was able to capture several images of the tiny, odd-shaped ring-moons from closer perspectives than ever before. I find it really hard to wrap my head around all the scales in the Saturn system so I thought it was time to produce another of my patented size comparisons of planetary bodies. As it turns out, there are orders of magnitudes of scales in the Saturn system and it wasn't sufficient for me to produce one such size comparison.

Here's the first comparison I produced. When you enlarge it to its full resolution, it has 100 meters per pixel. These are all the smallish moons in close orbits around Saturn (with the exception of Phoebe, which is a bit out of place here, representing all the wayward irregular moons in distant orbits). It's astounding to me how much diversity and size variation there is even among Saturn's smallest moons. There's this weird transition from lumpy to smooth that happens at the very smallest sizes, where the tiniest moonlets appear to be covered with a gravity-smoothed, deep coating of ringsnow that must be the puffiest substance imaginable. I'll bet you could fly right into the outer layers of one of those moons and sploof out the other side, leaving in your wake a super-slow-motion eruption of fine ringsnow material that the motion of your passage produced.
