There are more things...
Have you ever seen an ARTIFICIAL MOON?
The website of the European Space Agency (ESA) says:
"The most unique, and perhaps most remarkable feature discovered on Iapetus in Cassini images is a topographic ridge that coincides almost exactly with the geographic equator. The ridge is conspicuous in the picture as an approximately 20-kilometre wide band that extends from the western (left) side of the disc almost to the day/night boundary on the right. On the left horizon, the peak of the ridge reaches at least 13 kilometres above the surrounding terrain. Along the roughly 1300-kilometre length over which it can be traced in this picture, it remains almost exactly parallel to the equator within a couple of degrees. The physical origin of the ridge has yet to be explained." (http://sci.esa.int/science-e/www/object/index.cfm?fobjectid=35229&fbodylongid=1654)
