Ångström is a small lunar impact crater located on the border between Oceanus Procellarum to the west and Mare Imbrium to the east. To the south is a formation of mountains rising out of the mare named the Montes Harbinger. To the east are some wrinkle ridges named the Dorsum Bucher and Dorsa Argand. This crater is bowl-shaped, with a circular rim and inner walls that slope down to the small central floor. It has a higher albedo than the surrounding maria.[2] The crater halo is radar dark, indicating a lack of larger blocks among the fine ejecta.[3]

Ångström crater is named after Anders Jonas Ångström,[1] a Swedish physicist and one of the founders of the science of spectroscopy.

Satellite craters[]

By convention these features are identified on lunar maps by placing the letter on the side of the crater midpoint that is closest to Ångström.[2]
