Ritchey is a small lunar impact crater named after the American astronomer George W. Ritchey. The crater is situated to the east of Albategnius in the central lunar highlands, it is also northeast of Burnham, and west of Andĕl. 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. North of Ritchey is a satellite crater known as Ritchey F, its southernmost rim is only hilly and is almost missing, its elevation is nearly the same as the main crater.
Satellite craters
By convention these features are identified on lunar maps by placing the letter on the side of the satellite midpoint that is closest to Ritchey.
