"Graun" is a member of the Eunomia family, a large group of S-type asteroids and the most prominent family in the intermediate main-belt. It orbits the Sun at a distance of 2.2–3.0 AU once every 4 years and 2 months (1,531 days). Its orbit has an eccentricity of 0.14 and an inclination of 15° with respect to the ecliptic. In February 1975, it was first identified as at the Karl Schwarzschild Observatory, extending the body's observation arc by 15 years prior to its official discovery observation at Palomar.
