Gregory is a lunar crater on the far side of the Moon. It is located to the southeast of Ibn Firnas crater, and north-northeast of Bečvář crater. About one crater diameter to the north is the smaller Morozov crater.
This is a worn and eroded crater formation. The northern rim is degraded due to impacts. Attached to the exterior of the southwest is 'Gregory Q', a satellite crater about the same size as Gregory. Within the interior is the remains of a small crater rim along the northwestern inner wall.
To the east of Gregory and leading away to the southeast is a crater chain designated Catena Gregory.
[edit] Satellite craters
By convention these features are identified on lunar maps by placing the letter on the side of the crater mid-point that is closest to Gregory crater.
