Arago (lunar crater)

The rim of Arago has a bulge in the western wall. There is a central ridge that runs towards the northern wall. The surface of the mare nearby is marked by wrinkle ridges, most notably to the east and southeast. To the north is a large lunar dome designated Arago Alpha (α). A similar-sized lunar dome is located an equal distance to the west, designated Arago Beta (β).

Arago is a crater of Eratosthenian age.
