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. 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.
Satellite A 1.67 kilometer-large
minor-planet moon was discovered orbiting
Kursk in 44.96 hours (or 1 day, 20 hours, and 57 minutes). == Naming ==
