The most noticeable marking; is a huge-ringed impact basin in Callisto

• The surface of this moon is ridged and resembles ice rafts.

• An underground ocean that is possibly 60 miles deep is covered by a frozen crust that is about 10 miles thick.

• It is the largest moon in the solar system, measuring 3,270 miles in diameter.

• Light and dark terrains, possibly ice and rock, are scattered across its splotchy surface.

• There are more than 400 volcanoes scattered across the surface of this moon.

• It has no visible impact crater because all impact sites have been covered up by lava from the numerous volcanoes.

Saturn’s approximate diameter.
