5380 Sprigg, provisional designation 1991 JT, is a background
Robert McNaught at Siding Spring Observatory in New South Wales, Australia.[8] It was named after Australian geologist Reg Sprigg.[2]
Orbit and classification
Sprigg is a non-
background population. It orbits the Sun in the central asteroid belt at a distance of 2.0–3.1 AU once every 4 years and 2 months (1,513 days). Its orbit has an eccentricity of 0.21 and an inclination of 9° with respect to the ecliptic.[1] A first precovery was taken at Palomar Observatory in 1980, extending the body's observation arc by 11 years prior to its official discovery observation at Siding Spring.[8]

Diameter and albedo
According to the survey carried out by NASA's
albedo of 0.280,[4][5] while the Collaborative Asteroid Lightcurve Link assumes a standard albedo for carbonaceous asteroids of 0.057 and calculates a larger diameter of 12.75 kilometers with an absolute magnitude of 13.2.[3]
