Gregory is a
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.[1]
The crater was named after 17th century Scottish astronomer and mathematician James Gregory by the IAU in 1970.[2] While Gregory itself was unnumbered, its satellite crater Gregory Q was known as Crater 282 prior to naming in 2006.[3][4]
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 Gregory.
