Heavily cratered body
- Iapetus is a heavily cratered body, and Cassini images have revealed large impact basins in the dark region, at least three of which are over 350 km wide. The largest has a diameter over 500 km; its rim is extremely steep and includes a scarp over 15 km high.

Iapetus is heavily cratered, and Cassini images have revealed large impact basins, at least five of which are over 350 km (220 mi) wide.
The surface of Iapetus is heavily cratered, with large impact basins up to 580 kilometres across. Surface darkening on Iapetus comes from organic materials left behind as ice in the warmer Cassini Region region sublimates.

Jan 7, 2005 · This view of Saturn's moon Iapetus captured by NASA's Cassini spacecraft shows how the dark, heavily cratered terrain of Cassini Regio transitions to a bright, icy terrain at high latitudes.
Jun 13, 2011 · The new study, led by Daniel Tamayo at Cornell University, analyzed the efficiency with which various other moons could produce dust as well as the likelihood with which Iapetus could scoop it up.
