Runge (crater)

Runge is a lunar impact crater that lies on the far side of the Moon, beyond the limb as seen from Earth. It is located within the Mare Ingenii, a lunar mare that lies in a large, poorly defined depression. To the south of Runge is the crater Thomson, and to the northeast is the flooded crater Koch.

Runge is a relatively well-defined crater with a circular rim. The inner walls slope down to a relatively flat interior floor that is marked only by a few tiny craterlets. The outer rim is only lightly eroded, and it retains a sharp edge. It is generally considered to be Copernican in age, meaning it was formed relatively recently in geological terms.

The name was officially adopted by the International Astronomical Union (IAU) in 1970, and it honors the German mathematician Carl Runge.
