Laupheim is a non-family asteroid from the main belt's background population.[3] It orbits the Sun in the outer main-belt at a distance of 2.5–3.8 AU once every 5 years and 6 months (2,018 days; semi-major axis of 3.13 AU). Its orbit has an eccentricity of 0.21 and an inclination of 23° with respect to the ecliptic.[2] The body's observation arc begins at Palomar in September 1985, about a month before its official discovery observation.[1]
The Collaborative Asteroid Lightcurve Link assumes a standard albedo for a carbonaceous asteroid of 0.057 and calculates a diameter of 17.86 kilometers based on an absolute magnitude of 12.47.[4]
Naming
This minor planet was named for Robert Clausen (born 1951) and his team at the public Laupheim Observatory (German: Volksternwarte Laupheim) in Laupheim, southern Germany.[1] It was named by the discoverer Carolyn Shoemaker who visited the observatory in 1998. Clausen founded an association of amateur astronomers in 1975 which organized traveling astronomical exhibitions and numerous international astronomy festivals. Since 1990, he and his co-workers have also been running a Zeiss planetarium.[1][11]
