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.[9] The asteroid was named after Danish astronomer Richard M. West.[2]
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.[1] The asteroid observation arc begins at Heidelberg one month after its official discovery observation in March 1938.[9]
