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. The dark patches seem to be made of organic materials similar to those found in early meteorites or comets.
Iapetus is heavily cratered, and Cassini images have revealed large impact basins, at least five of which are over 350 km (220 mi) wide.

Aug 1, 2019 · Usually known for its rings, the Saturn system is also home to some of our solar system’s most intriguing moons.
Apr 27, 2019 · Iapetus is heavily cratered, with the largest known crater being the 580 km wide Turgis Crater; which is 40% of the moon's diameter! The Voyager I and Voyager II encounters during 1980 and 1981 validated Cassini's original observations revealing a trailing hemisphere lighter in colour.
The image shows Iapetus' surface illuminated by reflected light from Saturn (not by the Sun) and is the highest resolution view acquired to date of this part of Iapetus' surface. Compared to the approximately one second exposure times used for imaging Iapetus' sunlit side, this view required a very long exposure time of 82 seconds.
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.
