Orbit and characterization
Hadwiger orbits the Sun at a distance of 2.4–2.7 AU once every 4 years and 1 month (1,497 days). Its orbit has an eccentricity of 0.06 and an inclination of 15° with respect to the ecliptic.[1] It is a member of the Maria family of asteroids.[5]
In the Tholen classification, Hadwiger is a carbonaceous CSU-type.[1] It has a rotation period of hours with a brightness variation of in magnitude.[4]
Naming
This minor planet was named in memory of Swiss mathematician Hugo Hadwiger (1908–1981), professor at the University of Berne for more than 40 years and very popular for his refined art of presentation.[2] The approved naming citation was published by the Minor Planet Center on 22 September 1983 (M.P.C. 8151).[8]
