 Iapetus
In December 2004, the Cassini spacecraft discovered a further extraordinary feature of Iapetus: a topographic ridge that coincides almost exactly with the geographic equator.
It is not yet clear whether the ridge is a mountain belt that has folded upward, or an extensional crack in the surface through which material from inside Iapetus erupted onto the surface and accumulated locally, forming the ridge.
Another theory holds that the dark coating consists of debris that was ejected by impact events on dark, outer satellites of Saturn, such as Phoebe, and then swept up by Iapetus as it moved in its orbit.

 Iapetus (moon)
Iapetus (eye-ap'-i-tus, Greek Ιαπετός) (British spelling: "Japetus") is the third-largest moon of Saturn (see: Saturn's natural satellites), discovered by Giovanni Domenico Cassini in 1671.
Iapetus is best known for its dramatic 'two-tone' coloration, but recent discoveries by the Cassini-Huygens mission have revealed several other unusual physical characteristics.
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 fact that the Iapetus landslide traveled many kilometers from the basin scarp could indicate that the surface material is very fine-grained, and perhaps was fluffed by mechanical forces that allowed the landslide debris to flow extended distances.

Iapetus [eye-AP-i-tus] is one of the stranger moons of Saturn.

 Saturn's Moon Iapetus Shows a Bulging Waistline - Space - RedOrbit
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.
Consequently, despite the large relative speed between Iapetus and the spacecraft during this long exposure -- about 2 kilometers per second or almost 4,500 miles per hour at closest approach -- the image of the moon's surface is un-smeared (although the background stars are smeared).
However, the occurrence of some young-appearing craters on Iapetus that have bright north-facing and dark south-facing slopes, and the pattern of streaks near the north pole of Iapetus suggests that another mechanism may be responsible for the crater wall brightness asymmetries on Iapetus.

Iapetus is one of the icy moons, similar to the Galilean satellites.
Iapetus is about as wide as California is long, 1440 km, or 960 miles, which makes it about the same size as Rhea, a moderately large icy moon.

The dark material covers precisely the side of Iapetus that leads in the direction of orbital motion around Saturn (except for the poles), whereas the bright material occurs on the trailing hemisphere and at the poles.
Iapetus is 907 miles (1,460 kilometers) wide and circles Saturn at a distance of about 2.2 million miles (3.6 million kilometers).
Oddly, the side of Iapetus that always faces forward as it moves along its orbital path -- think of the front of a race car on a circular track -- reflects just 5 percent of the sunlight that hits it.

 Saturn's Moon, Iapetus
Iapetus is the third largest of Saturn's moons, with a diameter of 900 miles.
One suggestion is that Iapetus has had episodes of ice vulcanism which has released methane-rich materials from the interior, and subsequent darkening of the methane ice by the absorption of ultraviolet radiation from the Sun has made the material quite dark.
However, the color of the dark material on Iapetus is slightly different from that of Phoebe, and sweeping up debris should lead to a fuzzier boundary between the light and dark areas.

In Greek mythology, Iapetus was a Titan – a God - the son of Uranus and Gaia and the ancestor of mankind.
He suggested that Iapetus had a light side and a dark side, and that it always kept the same face turned to Saturn (in the same way that our moon always keeps the same face turned to the Earth).
The consensus of opinion is that Iapetus, and many of the moons of similar density, is/are made mainly from water ice.
