Clerke is a tiny lunar impact crater named after Irish astronomer Agnes Mary Clerke,[1] who played a role in bringing astronomy and astrophysics to the public in Victorian England.[2] It is located near the eastern edge of Mare Serenitatis in the midst of a rille system named the Rimae Littrow after the crater Littrow to the east. It is roughly circular and cup-shaped, with a relatively high albedo. In a valley to the southeast is the landing site of the Apollo 17 mission. Clerke was previously designated Littrow B.
