Caption: "Description: Southward looking oblique view of Mare Imbrium and Crater Copernicus on the Moon. Copernicus is seen almost edge-on near the horizon at the center. The crater is 107 km in diameter and is centered at 9.7 N, 20.1 W. In the foreground is Mare Imbrium, peppered with secondary craters chains and elongated secondary craters due to the Copernicus impact. The large crater near the center of the image is the 20 km diameter Crater Pytheas, at 20.5 N, 20.6 W. At the upper edge of the Mare Imbrium are the Montes Carpatus. The distance from the lower edge of the frame to the center of Copernicus is about 400 km. This picture was taken by the metric camera on Apollo 17, 1972 (Apollo 17, AS-2444)." (Slightly edited.)

Copernicus has a rim diameter of about 90 km and is one of the largest craters on the Moon.

The Copernicus impactor must have been a few kilometers in diameter (HI-141).

Copernicus is a peaked crater and a terraced crater.
