Grimaldi Q (Moon)

Satellite Feature of Grimaldi

Named after Francesco Maria Grimaldi - Italian astronomer, physicist (1618-1663).

Grimaldi is a large basin located near the western limb. It lies to the southwest of the Oceanus Procellarum, and southeast of the crater Riccioli. Between Oceanus Procellarum is Damoiseau, and to the north is Lohrmann. The inner wall has been so heavily worn and eroded by subsequent impacts that it forms a low, irregular ring of hills, ridges and peaks, rather than a typical crater rim. (wikipedia entry)
