   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. The largest, Turgis , has a diameter of 580 km (360 mi); [24] its rim is extremely steep and includes a scarp about 15 km (9.3 mi) high. [25]

   Is Iapetus a crater?

   • Due to Iapetus’ unexplained inclined orbit, it is the only major moon around Saturn from which the rings can be seen. All the other large moons are side on to the thin rings. Iapetus is heavily cratered, with the largest known crater being the 580 km wide Turgis Crater; which is 40% of the moon's diameter!

   Jan 7, 2005 · The scene is dominated by a dark, heavily-cratered region, called Cassini Regio, that covers nearly an entire hemisphere of Iapetus. Iapetus is 1,436 kilometers (892 miles) across. The view is centered on the moon’s equator and on roughly 90 degrees west longitude -- a location that always faces the direction of Iapetus's orbital motion ...
