The northeast rim of Eratosthenes crater is easily seen as the change in reflectance due to differing slopes - higher reflectance terrain in the lower left is the steeply sloping interior. LROC NAC image M117562615L, image width is 600 meters (197 feet).

Eratosthenes crater is found in the central nearside, east-northeast of Copernicus crater (latitude 14.5, longitude 348.7). Eratosthenes is named for the ancient Greek who first estimated the Earth's circumference around 240 BC.

NASA's Goddard Space Flight Center built and manages the mission for the Exploration Systems Mission Directorate at NASA Headquarters in Washington. The Lunar Reconnaissance Orbiter Camera was designed to acquire data for landing site certification and to conduct polar illumination studies and global mapping. Operated by Arizona State University, LROC consists of a pair of narrow-angle cameras (NAC) and a single wide-angle camera (WAC). The mission is expected to return over 70 terabytes of image data.
