Landslides on Saturn's moon, Iapetus, raise interest

Iopitus is a moon characterized by its squashed spherical shape and a prominent Ridge. The Ridge features peaks that can reach heights more than twice that of Mount Everest. The moon's surface is marked by deep craters, and its conditions allow landslides to travel up to 30 times their vertical falling distance, a stark contrast to Earth's landslides, which typically travel less than twice their vertical falling distance.
