2126 Gerasimovich, provisional designation 1970 QZ, is a stony background asteroid from the inner regions of the asteroid belt, approximately 8 kilometers in diameter. It was discovered on 30 August 1970, by Soviet astronomer Tamara Smirnova at the Crimean Astrophysical Observatory in Nauchnyj, on the Crimean peninsula.[11] The asteroid was named after Russian astronomer Boris Gerasimovich.[2]
Gerasimovich is a non-family asteroid from the main belt's background population.[4] It orbits the Sun in the inner asteroid belt at a distance of 2.1–2.7 AU once every 3 years and 8 months (1,349 days; semi-major axis of 2.39 AU). Its orbit has an eccentricity of 0.12 and an inclination of 8° with respect to the ecliptic.[1]
The body's observation arc begins with its first identification as 1931 AQ at Lowell Observatory in January 1931, almost 40 years prior to its official discovery observation at Nauchnyj.[11]
