Brayley is a lunar impact crater located in the southwest part of the Mare Imbrium. It dates to the Eratosthenian age on the lunar geologic timescale.[2] This crater has a circular rim with darker radial bands on the interior and a low rise in the center.[3] There are no notable craters overlapping the rim or interior, although the outer ejecta blanket has been partially buried by subsequent lava flows.[4] The slender, sinuous rille Rima Brayley passes to the northwest of Brayley, extending for a length of about 240 km.[5]

This formation is named after British geographer Edward W. Brayley (1801–1870). His name was introduced into lunar nomenclature by William R. Birt and John Lee.[6] Its designation was formally adopted by the International Astronomical Union in 1935.[7]

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 Brayley.[8]
