At the time of Copernicus' formation, an enormous amount of material from the lunar soil, fragmented by the meteorite impact, was expelled outwards, forming the myriad of small craters that surround the crater itself. Note the impact radius. The slight saturation of the colors highlights the areas adjacent to the Copernicus crater which are darker and richer in titanium. The Eratosthenes crater and the Stadius ghost crater are also present in the image. On the bottom right, the Archimede crater with the small internal craters.
