Hyperion is one of the largest highly irregular (non-spherical) bodies in the solar system (second to Proteus). The largest crater on Hyperion is approximately 120 km in diameter and 10 km deep. A possible explanation for the irregular morphology is that Hyperion is a fragment of a larger body that was broken by a large impact in the distant past, an event which has been linked to the enigmatic darkening of Iapetus.
