Chekhov is a crater on Mercury. It has a diameter of 194 kilometers.[1] Its name was adopted by the International Astronomical Union (IAU) in 1976. Chekhov is named for the Russian author Anton Chekhov, who lived from 1860 to 1904.[2]
Chekhov is one of 110 peak ring basins on Mercury.[3] On the eastern side of the peak ring is a dark spot of low reflectance material (LRM), closely associated with hollows.[4] There is evidence of explosive volcanism on the floor of the crater, based on the presence of an irregular depression along the southern inner peak ring.[5]
The small rayed crater Popova is to the west of Chekhov. Unkei is to the north, Wergeland is to the east, and the similar-sized crater Schubert is to the southeast.
