Surface of Ganymede

The surface of Ganymede is halfway between Callisto and Europa.

There are portions of the surface of Ganymede that have many craters, like Callisto and there are portions which are relatively new, and have no craters. This picture shows those two sides of Ganymede.

The little white dots are the many craters of Ganymede.

The surface of Ganymede shows grooves, light colors, and dark colors.

The many different kinds of surface found on Ganymede are proof that it has changed on the inside during it's history.
