2483 Guinevere (1928 QB) is a 44 km outer main-belt asteroid discovered on August 17, 1928 by Max Wolf at Heidelberg.[1] It is a member of the Hilda family of asteroids that are in a 3:2 orbital resonance with Jupiter. In a 1998 numerical integration by Dahlgren, Guinevere was the Hilda asteroid with the greatest chance of impacting with another asteroid.[2] About 74% of the impact risk occurs when Guinevere is relatively close to perihelion and approaches the main-belt asteroids.
