Copernicus tiene algunos picos centrales (no visibles en la images) que se elevan hasta 1 200 m sobre el fondo del cráter, mientras Erastosthenes tiene un borde muy bien definido, con terrazas interiores, y montañas centrales. Son muy bonitas las rrapas de eyyeción de material.
Copernicus has a some central peaks (not seem on the image) consist of three isolated mountainous rises climbing as high as 1.2 km above the floor. These peaks are separated from each other by valleys, while Erastosthenes has a well-defined circular rim, terraced inner wall, central mountain peaks, an irregular floor, and an outer rampart of ejecta. It lacks a ray system of its own, but is overlain by rays from the prominent crater Copernicus to the south-west.
