Iapetus (moon)

English: Iapetus, also Japetus, is the third-largest moon of Saturn, discovered by Giovanni Domenico Cassini in 1671. Iapetus is best known for its dramatic 'two-tone' coloration, but recent discoveries by the Cassini mission have revealed several other unusual physical characteristics. These mysteries are currently under investigation by scientists, and new information about Iapetus is accumulating continuously.
