The Surface of Enceladus
The surface of Enceladus does not have many craters. Instead it has grooves similar to those found on
Ganymede. These grooves extend for many kilometers over the surface.
The presence of grooves indicates that there has been activity in the interior of Enceladus in the past. In fact, much of Enceladus's surface is quite young, less than 100 million years old.
Enceladus is also the most highly reflective large object in our solar system. Even more reflective than newly fallen snow.
