Iapetus (moon)
Iapetus ( / aɪ ˈ æ p ɪ t ə s / ; Greek : Ιαπετός ), or occasionally Japetus / ˈ dʒ æ p ɪ t ə s / , [7] is the third-largest natural satellite of Saturn , eleventh-largest in the Solar System , [8] and the largest body in the Solar System known not to be in hydrostatic equilibrium . [9] Iapetus is best known for its dramatic "two-tone" coloration. Discoveries by the Cassini mission in 2007 revealed several other unusual features, such as a massive equatorial ridge running three-quarters of the way around the moon.

Its density is similar to that of Rhea , indicating that it has a small amount of rocky materials. Its leading side is dark ( albedo 0.03-0.05) with a slight reddish color while its trailing side is bright (albedo 0.5, almost as bright as Europa ). This difference is so striking that Cassini noted that he could see Iapetus only on one side of Saturn and not on the other. The dark surface might be composed of matter that was either swept up from space or oozed from the moon's interior; the real source is still unknown. The dark material might be a thin layer of organic material perhaps similar to the complex substances found in the most primitive meteorites . However, there are no bright-rimed craters present on the dark hemisphere; If the dark material is thin, it must be constantly renewed since a meteor impact would punch through the layer to reveal brighter surface material. |
