Description
Chebyshev is a 3.92 to 3.85 bn years old crater of the Nectarian-age . It lies within the north-eastern, outer ring sector of the South Pole Aitken Basin -- a 2500 kilometre-wide basin of the pre-Nectarian period (~ 4.6 to 3.92 bn years), some 200 km east of the Apollo Basin (pre-Nec -- 4.6 to 3.92 bn years old), and approximately 1000 km away from the Hetzsprung Basin (Nectarian) to its north. The crater itself shows a relatively worn-looking rim all around, with broken-up terracing seen particularly towards its northern and southern regions. The eastern and western sections have been affected by cratering impacts; most particularly the major impact event of Langmuir (91 km across) in the south-eastern sector. Besides the relatively flat-looking floor of Chebyshev having several small, numerous impact craters all around to speak of, two impact craters of note stand out -- that of the slightly distorted, assymetric shaped, 40 kilometer-wide crater to the south-east, and the other west of central. This latter crater shows sign of, perhaps, a deep-rooted, linear rille towards its western sector, or, is this simply due to several merged craters that formd a chain, or perhaps a fault section in the region? In fact, the above-mentioned craters may be the result of secondary crater impacts from the above-mentioned basin, Hertsrpung, or from the most early impact basin of them all -- that of Orientale, which lies easterly to Chebyshev some 1200 km away. - JohnMoore2

Additional Information
Nomenclature
- Chebyshev Z was officially approved by the IAU on the 25 July 2017 - JohnMoore2
- Pafnuty Lvovich Chebyshev (May 16, 1821 - December 8, 1894) was a Russian mathematician. Chebyshev is known for his work in the field of probability, statistics and number theory. Chebyshev is considered a founding father of Russian mathematics.
- An unnamed crater at 131° West/ 28° South (north-northeast of Chebyshev) was once called Rastorguev (crater N° 642 on this section of the Second Complete Moon Map, 1969 of the Shternberg Astronomy Institute). Research: Danny Caes.
- On the same moonmap's section, a crater immediately west of the above mentioned Rastorguev was once called Drashusov (N° 280). Research: Danny Caes.
