It was discovered on 8 October 1969, by Soviet astronomer Lyudmila Chernykh of the Crimean Astrophysical Observatory at Nauchnij, on the Crimean peninsula. The assumed C-type asteroid has a rotation period of 8.1 hours and possibly an elongated shape. It was named for the Russian Sternberg Astronomical Institute (GAISh) of Moscow State University. Orbit and classification GAISh is a non-family asteroid from the main belt's background population. It orbits the Sun in the outer asteroid belt at a distance of 2.8–3.4 AU once every 5 years and 6 months (2,016 days; semi-major axis of 3.12 AU). Its orbit has an eccentricity of 0.09 and an inclination of 6° with respect to the ecliptic. The body's observation arc begins with its official discovery observation in October 1969. Physical characteristics GAISh is an assumed carbonaceous C-type asteroid. Rotation period In October 2010, a rotational lightcurve of GAISh was obtained from photometric observations in the R-band by astronomers at the Palomar Transient Factory in California. Lightcurve analysis gave a rotation period of 8.086 hours with a high brightness amplitude of 0.82 magnitude, indicative of a non-spherical shape (U=2). Diameter and albedo According to the survey carried out by the NEOWISE mission of NASA's Wide-field Infrared Survey Explorer, GAISh measures 15.256 kilometers in diameter and its surface has an albedo of 0.076. The Collaborative Asteroid Lightcurve Link assumes a standard albedo for a carbonaceous asteroid of 0.057 and calculates a diameter of 11.42 kilometers based on an absolute magnitude of 13.44. Naming This minor planet was named after the Sternberg Astronomical Institute (GAISh, ГАИШ), a division of Moscow State University. Founded in 1931, it is one of Russia's leading astronomical institute and a principal educational facility for professional astronomers. The institute is located on the site of the 1931-built Sternberg Observatory. The official naming citation was published by the Minor Planet Center on 6 January 2007 (M.P.C. 58595).
