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.

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.

Jul 17, 2007 · Saturn's distinctive moon Iapetus (eye-APP-eh-tuss) is cryogenically frozen in the equivalent of its teenage years. The moon has retained the youthful figure and bulging waistline it sported more than three billion years ago, scientists report.
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.
Jan 7, 2005 · This oblique view of Saturn's moon Iapetus from high latitude shows how the dark, heavily cratered terrain of Cassini Regio transitions to a bright, icy terrain at high latitudes. In this mosaic of two high resolution images taken during Cassini's New Year's Eve 2004 flyby of Iapetus, the direction toward the north pole is approximately 15 ...
Iapetus has been called the yin and yang of the Saturn moons because its leading hemisphere has a reflectivity (or albedo) as dark as coal (albedo 0.03-0.05 with a slight reddish tinge) and its trailing hemisphere is much brighter at 0.5-0.6. Saturn's third largest moon, Iapetus has a mean radius of 457 miles (736 kilometers) and a density only ...
