The Surface of Dione
The surface of Dione does not have many craters, which means that the surface has changed in the past.
Instead of many craters, it has wispy white streaks like the ones on Rhea, which go for many kilometers over the whole surface.
These things are signs that there may have been activity within Dione a long time ago.
