Go Back

Crater degredation on Callisto and Ganymede Callisto is unique among the Galilean satellites of Jupiter for the process by which its craters appear to fall apart over time, "until they look like Stonehenge." This is quite different to the way that craters degrade on other icy worlds, where viscous relaxation eventually flattens them out.
