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. At least some of its surface is relatively young and less than 100 million years old (a blink of the eye to the solar system ).
