Hyperion 

Hyperion is one of the smallest moons of Saturn. It was discovered by William Cranch Bond and has one of the strangest shapes of all satellites ever discovered. It is theorized that Hyperion once was a much larger moon that shattered into pieces, the result of a major collision between another large body. The satellite has an extremely eccentric rbit that tumbles crazily through space when interacting with Saturn's gravitational force. One of its largest craters on the surface is 120 kilometers (75 miles) wide and 10 kilometers (6.2 miles) deep. The rest of the surface is also heavily cratered and indicates that it could be the oldest moon of Saturn.
