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. Selenographic coordinates are used to refer to locations on the surface of Earths moon. ...

The depth of any crater in a solid planet or moon - whether it is an impact crater, a volcanic crater, or a subsidence crater - may be measured from the local surface to the bottom of the crater, or from the rim of the crater to the bottom. ...

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.

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.
