Denning (lunar crater)
The lunar crater Denning is to the upper left. Note the bright patch at right center. NASA photo.Coordinates 16°24′S 142°36′E / 16.4°S 142.6°ECoordinates: 16°24′S 142°36′E / 16.4°S 142.6°E Diameter 44 km Depth Unknown Colongitude 218° at sunrise Eponym William F. Denning Denning is a lunar crater that is located on the far side of the Moon. It lies about midway between the craters Levi-Civita to the south and Marconi to the north-northeast. About two crater diameters to the southeast is the huge walled plain Gagarin.
The rim of this worn crater is circular but somewhat irregular-edged. There is a low central rise at the mid-point consisting of at least two hills. Attached to the southwest outer rim is the larger satellite crater Denning R. About one crater diameter the southeast of Denning is a bright patch of high-albedo surface. This patch was most likely created by a small, relatively recent impact.
Satellite craters
By convention these features are identified on lunar maps by placing the letter on the side of the crater mid-point that is closest to Denning.
