Autolycus (39 km) in the lower right corner; It is a deep crater about 3.4 km deep. Luna 2, the first probe to reach the Moon, in 1959, landed (fell) between Archimedes and Autolycus. Aristillus (55 km) is in the upper right corner, has beautiful twin walls and a complex group of central peaks rising to 0.9 km above the floor of the crater, peaks that in this photo I was able to highlight in all its beauty. Aristillus is a relatively young crater, it is the center of a system of rays very apparent in the Full Moon. The Archimedes flooded crater (83 km), which in this photo appears cut in half, has a depth of 2.1 km and its two largest internal craterelets, T on the left and S on the right (in the shade), are both 3 km in diameter . A crater flooded on the northern outer walls of Aristillus is actually a remnant of ghost crater. It has only one protruding ledge and should be an ancient crater that was almost completely submerged by the lava flows around the Mare Imbrium, its southern end was completely covered by the ejection of Aristillus. Mounts Spitsbergen, an isolated mountain range is perfectly visible on the left side.
