Image of the lunar surface, looking south across Mare Imbrium, with the crater Copernicus (58 miles in diameter) visible in the distance, in an image of the lunar surface taken during the Apollo 17, 7th to 19th December 1972. Crater Pytheas (12 miles in diameter) is visible in the foreground, with several chains of small craters beyond, these are oriented toward Copernicus and are secondary craters produced by material ejected when Copernicus formed.
