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]

Iapetus has a bright and a dark hemisphere, with a ridge running along its equator. The dark region is called Cassini Regio and is the principal feature of the leading hemisphere. The surface of Iapetus is heavily cratered, with large impact basins up to 580 kilometres across.
Oct 5, 2021 · But it doesn’t. Iapetus is tidally locked to Saturn, meaning it rotates only once every 79 days.

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.
Aug 9, 2021 · The equatorial ridge of Iapetus. When Cassini flew by on Decembr 31, 2004, a ridge was discovered on Iapetus. It is 1300 km long, 20 km wide, and 13 km high. It follows Iapetus' equator almost perfectly, and is heavily cratered, and therefore ancient. For now, scientists are not sure of the origins of the ridge.
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 around ...
The region appears heavily cratered, particularly in the north and south polar regions. Near the top of the mosaic, numerous impact features visible in NASA Voyager 2 spacecraft images (acquired in 1981) are visible, including the craters Ogier and Charlemagne.
