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. Surface darkening on Iapetus comes from organic materials left ...
Oct 12, 2015 · Iapetus has the slowest spin of any Saturnian moon, and its 79.3-day rotation creates lengthy, warm days and long, bitterly cold nights. The sunlit ice turns directly to water vapor (a process ...

Jan 7, 2005 · Iapetus: A View from the Top. 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 ...
Jan 1, 2005 · Iapetus by Saturn Shrine. This almost surreal view of Iapetus was acquired by Cassini about 10 minutes after the spacecraft's closest approach to the icy moon during a close flyby on New Year's Eve 2004. The image shows Iapetus' surface illuminated by reflected light from Saturn (not by the Sun) and is the highest resolution view acquired to ...

Jan 7, 2005 · On New Year's Eve 2004, Cassini flew past Saturn's intriguing moon Iapetus, capturing the four visible light images that were put together to form this global view. 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 ...
The Cassini spacecraft imaged a remarkable narrow ridge encircling much of Iapetus’s equator. The ridge is about 20 km (13 miles) high and 20 km wide, and some areas are punctuated by a system of mountains about 10 km (6 miles) high. The heavily cratered surface of the ridge implies that it was formed very early in the history of Iapetus.
