Iapetus ( "eye AP i tus" ) is the seventeenth of Saturn 's known satellites and the third largest: orbit : 3,561,300 km from Saturn diameter : 1460 km mass : 1.88e21 kg . ... With a density of only 1.1, Iapetus must be composed almost entirely of water ice. The leading and trailing hemispheres of Iapetus are radically different. The albedo of the leading hemisphere is between .03 and .05, as dark as lampblack, whereas the trailing hemisphere's albedo is .5, almost as bright as Europa . ...
