Hyperion is an irregularly shaped moon and like most of these was thought to be a “captured” moon of Saturn, which is an object that strays too close to a larger body and is pulled into its orbit. Soon other theories suggested that perhaps it was a single fragment of some larger body which was largely destroyed and perhaps is what littered Iapetus with its darker material. Now, closer observations show us that much of Hyperion’s interior is hollow space... or nothing... which could mean that Hyperion is actually a collection of smaller fragments of ice and some rock which over time pulled itself together to form Hyperion. In other words an orbiting pile of rubble.

The ridge at Iapetus’s equator from only 3,148 km. The black and white nature of Iapetus is only one of its [bizarre] traits, the other is the huge mountain range that runs almost completely around its equator. This the feature that often causes the mainstream media to compare the moon to a walnut.
