Bouguer (lunar crater)
Crater on the Moon
From Wikipedia, the free encyclopedia
Bouguer is a lunar impact crater that lies along the southern edge of the Mare Frigoris,[2] to the north of the crater Bianchini. To the west-southwest of Bouguer, along the same shore of the mare, is the crater Foucault. Nearly due west is the more prominent Harpalus, and to the east is La Condamine.[3]

This is a relatively young crater with well-defined edge. The formation is relatively circular, but there are slight outward bulges to the east, north-northwest, and southwest. There is some evidence of slumping in the eastern bulge. The interior floor occupies about half the crater diameter, and is relatively level and featureless.[4]: 11
This crater is named after French hydrographer Pierre Bouguer (1698-1758).[1] His name was introduced into lunar nomenclature by German astronomer J. H. von Mädler during the 19th century.[5] Its designation was formally adopted by the International Astronomical Union in 1935.[1]
