Hamlet (Oberon)

Shakespearean hero.

Hamlet is the largest crater on the known part of the surface of Uranus' moon Oberon. The nature of the dark material on the floor is not known, but it may have erupted from depth. The crater was first imaged by the Voyager 2 spacecraft in January 1986. (wikipedia entry)

A crater is a circular depression likely created by an impact event. On Oberon they are named after shakespearean tragic heroes and places.
