3073 Kursk, provisionally known as 1979 SW11, is a stony Florian asteroid and synchronous binary system from the inner regions of the asteroid belt, approximately 4.7 kilometers in diameter. It was discovered on 24 September 1979, by Soviet astronomer Nikolai Chernykh at the Crimean Astrophysical Observatory in Nauchnyj, on the Crimean peninsula.[5]
Orbit and characterization
Kursk is a member of the Flora family, one of the largest families of stony S-type asteroid in the main belt. It orbits the Sun in the inner main-belt at a distance of 1.9–2.5 AU once every 3 years and 4 months (1,227 days). Its orbit has an eccentricity of 0.14 and an inclination of 5° with respect to the ecliptic.[1]
The Collaborative Asteroid Lightcurve Link assumes an albedo of 0.24 – derived from 8 Flora, a S-type asteroid and the family's largest member and namesake – and derives a diameter of 4.67 kilometers with an absolute magnitude of 13.86.[3]
Satellite
A 1.67 kilometer-large minor-planet moon, designated S/2007 (3073) 1 was discovered orbiting Kursk in 44.96 hours (or 1 day, 20 hours, and 57 minutes).[4]
Naming
This minor planet was named after the old Russian city Kursk.[2] The approved naming citation was published by the Minor Planet Center on 2 July 1985 (M.P.C. 9771).[6]
