Atwood lies near the edge of the outer ramparts of Langrenus, and the ejecta forms low ridges attached to the south rim of Atwood. Within the crater interior is a low central peak that joins a ridge line to the north rim of the crater.
Atwood was formerly designated Langrenus K, before being renamed by the IAU in 1976.[1]
