Ritchey (lunar crater)
Ritchey is a small lunar impact crater named after the American astronomer George Willis Ritchey.[1] The crater is situated to the east of Albategnius in the central lunar highlands. Its somewhat angular rim is broken along the northwestern wall by a pair of smaller, adjacent craters. The floor of Ritchey is fairly flat, with a pair of small central mounds.
