3073 Kursk, provisionally known as1979 SW11, is a stony Florianasteroid and synchronousbinary system from the inner regions of theasteroid belt, approximately 4.7 kilometers in diameter. It was discovered on 24 September 1979, by Soviet astronomerNikolai Chernykh at theCrimean Astrophysical Observatory in Nauchnyj, on the Crimean peninsula.[5]
Kursk is a member of theFlora family, one of the largest families of stonyS-type asteroid in the main belt. It orbits the Sun in theinner main-belt at a distance of 1.9–2.5 AU once every 3 years and 4 months (1,227 days). Its orbit has aneccentricity of 0.14 and aninclination of 5° with respect to theecliptic.[1]
TheCollaborative Asteroid Lightcurve Link assumes an albedo of 0.24 – derived from8 Flora, aS-type asteroid and the family's largest member and namesake – and derives a diameter of 4.67 kilometers with anabsolute magnitude of 13.86.[3]
A 1.67 kilometer-largeminor-planet moon was discovered orbitingKursk in 44.96 hours (or 1 day, 20 hours, and 57 minutes).[4]
Thisminor planet was named after the old Russian cityKursk.[2] The approved naming citation was published by theMinor Planet Center on 2 July 1985 (M.P.C. 9771).[6]
