Geological Chronicle
Vetchinkin is a degraded lunar impact crater located on the far side of the Moon, to the west-northwest of the huge walled plain named Mendeleev. Measuring 94.29 kilometers in diameter, it lies between Meshcherskiy to the west-northwest and Green to the south-southeast.
The crater is heavily worn and eroded, leaving little of the original outer rim. The satellite crater Vetchinkin K falls across the eastern side of the rim, while Vetchinkin Q forms a small crater in the southwestern floor, surrounded by minor impacts that blend into the battered terrain.
The crater was known as Crater 215 before being named in 1970 by the IAU for Soviet physicist and engineer Vladimir Vetchinkin.
