Tags: Crater.
Runge is a lunar crater in the Mare Smythii along the eastern edge of the Moon. It lies less than one crater diameter to the north-northwest of the very similar crater Warner. To the west-northwest is Haldane. Runge has been almost completely submerged by basaltic lava leaving only a low ring-shaped feature in the lunar mare. The rim has a gap at the southern end and a pair of small craters lie near the exterior to either side of this opening.
