Giant craters deform the shape of Saturn's moon, Hyperion, making it the largest irregularly shaped body in the solar system.

This natural satellite of the ringed planet possesses such a low density (about half that of water) and such low gravity that other objects colliding with it tend to compress its surface, rather than excavating it, and most material that is blown outward escapes into space.

Hyperion measures 174 miles (280 kilometers) across.

The image was taken in visible green light with Cassini spacecraft's narrow-angle camera on July 23, 2007. The spacecraft obtained the view at a distance of approximately 198,000 miles (318,000 kilometers) from Hyperion. The image scale is 1 mile (2 kilometers) per pixel.
