Avogadro is an ancient lunar impact crater that is located in the northern hemisphere on the far side of the Moon.[3] On the lunar geologic timescale, this formation is dated to the Pre-Nectarian period.[2] The formation has been heavily worn and eroded by subsequent impacts, so that the rim is now little more than a rounded edge surrounding the crater depression. The crater floor is equally worn, being covered in a multitude of smaller craters of various sizes. Many of these smaller craters have also been eroded, leaving little more than a faint trace on the surface.[4]: 7, 18

Nearby craters of note include Tikhov, which is nearly attached to the southeast rim,[5] Oberth to the west, and Schjellerup to the north-northwest. To the south-southwest is the crater Yamamoto, and farther to the south is the large walled plain D'Alembert.[4]: 7, 18
This crater is named after the Italian scientist Amedeo Avogadro (1776–1856).[6] Its designation was formally adopted by the International Astronomical Union in 1970.[1]
