EponymWilliam Congreve

Congreve is a degraded lunar impact crater that is located on the far side of the Moon relative to the Earth,[3] and lies across the lunar equator. It lies to the west-northwest of the massive walled plain designated Korolev. To the southeast is the crater Icarus, and due north is Zhukovskiy.[4]

On the lunar geologic timescale, this crater was formed during the Nectarian age.[2] The rim of this crater is worn by impact erosion, particularly along the eastern side where a pair of small crater lie along the edge. The rim and inner wall are more prominent to the west and north, while it forms only a shallow ridge to the southeast. The interior floor is marked by a cluster of small craters in the northeastern part, and tiny craterlets scattered across the remainder.[5]: 87 

This crater is named after British inventer and rocketry pioneer William Congreve (1772–1828).[6] Its designation was officially adopted by the International Astronomical Union in 1970.[1]

Satellite craters

By convention these features are identified on lunar maps by placing the letter on the side of the crater midpoint that is closest to Congreve.[7]
