Valhalla Crater on Callisto. Callisto is the most heavily cratered satellite in the Solar System. Its surface has apparently been primarily sculpted by impacts. Valhalla is its largest crater - it's 360 km (225 miles) across and the rings extend to 1900 km (1190 miles) from its center.

Callisto is a moon of the planet Jupiter. It was discovered in 1610 by Galileo Galilei. It is the third-largest moon in the Solar System and the second largest in the Jovian system, after Ganymede. Callisto has about 99% the diameter of the planet Mercury but only about a third of its mass. It is the fourth Galilean moon of Jupiter by distance, with an orbital radius of about 1,880,000 km.

Saturn's Hyperion: A Moon with Odd Craters Credit: Cassini Imaging Team, SSI, JPL, ESA, NASA What lies at the bottom of Hyperion's strange craters? Nobody's sure. To help find out, the robot Cassini spacecraft now orbiting Saturn swooped past the sponge-textured moon in 2005 and 2010 and took images of unprecedented detail. An image from the 2005 pass, shown above in false color, shows a remarkable world strewn with strange craters and a generally odd surface...
