2022 West, provisional designation 1938 CK, is a stony asteroid from the middle regions of the asteroid belt, approximately 12 kilometers in diameter. It was discovered by German astronomer Karl Reinmuth at Heidelberg Observatory on 7 February 1938. The asteroid was named after Danish astronomer  Richard M. West.
Classification and orbit
West orbits the Sun in the central main-belt at a distance of 2.4–3.0 AU once every 4 years and 5 months (1,625 days). Its orbit has an eccentricity of 0.12 and an inclination of 6 ° with respect to the ecliptic. The asteroid  observation arc begins at Heidelberg one month after its official discovery observation in March 1938.
SMASS classification, West is a common S-type asteroid.
In November 2016, a first rotational
lightcurve of West was obtained from photometric observations by Italian astronomers. Lightcurve analysis gave a rotation period of 14.14 hours with a brightness variation of 0.50 magnitude ( ). U=3-
According to the surveys carried out by the Japanese
Akari satellite and the NEOWISE mission of NASA's Wide-field Infrared Survey Explorer, West measures between 11.04 and 12.916 kilometers in diameter and its surface has an albedo between 0.1682 and 0.23.  
Collaborative Asteroid Lightcurve Link assumes a standard albedo for carbonaceous asteroids of 0.057 and consequently calculates a much larger diameter of 26.64 kilometers using an absolute magnitude of 11.6.
minor planet was named after Danish astronomer Richard Martin West (born 1941), an observer and discoverer of minor planets at the European Southern Observatory in La Silla. West also discovered 76P/West–Kohoutek–Ikemura, a bright comet of the Jupiter family. He also was the International Astronomical Union's general secretary (1982–1985) and president of its Commission XX (1988–1991). The approved naming citation was published by the  Minor Planet Center before November 1977 ( ). M.P.C. 4359
