    1289 Kutaïssi, provisional designation 1933 QR, is a stony asteroid from the outer region of the asteroid belt, about 26 kilometers in diameter. It was discovered by Soviet–Russian astronomer Grigory Neujmin at Simeiz Observatory on the Crimean peninsula on 19 August 1933.[11] The asteroid was independently discovered in Belgium and South Africa by the astronomers Eugène Delporte and Cyril Jackson on August 25 and September 11, respectively.[2]

    The S-type asteroid is a member of the Koronis family, a group consisting of about 200 known bodies, thought to have been formed at least two billion years ago in a catastrophic collision between two larger bodies. It orbits the Sun at a distance of 2.7–3.0 AU once every 4 years and 10 months (1,767 days). Its orbit shows an eccentricity of 0.06 and is tilted by 2 degrees to the plane of the ecliptic. It has a well-defined rotation period of 3.6 hours[8][9][10] and an albedo of 0.14–0.17, according to the surveys carried out by IRAS, Akari, WISE, and NEOWISE.[4][5][6][7]

    The minor planet was named after the city of Kutaisi, now the legislative capital of Georgia, and its second largest city, after the capital Tbilisi.[2]
