This crater is roughly circular, with an outer rim that has been slightly worn due to minor impacts. The northwestern rim in particular has merged with a smaller crater, and another impact lies on the interior floor along the west-northwestern inner wall.
Satellite craters
editBy convention these features are identified on lunar maps by placing the letter on the side of the crater midpoint that is closest to Walker.
