2151 Hadwiger, provisional designation1977 VX, is a Marianasteroid from the central region of theasteroid belt, approximately 15 kilometers in diameter. It was discovered on 3 November 1977, by Swiss astronomerPaul Wild atZimmerwald Observatory near Bern, Switzerland.[7]
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 aneccentricity of 0.06 and aninclination of 15° with respect to theecliptic.[1] It is a member of theMaria family of asteroids.[5]
In theTholen classification,Hadwiger is a carbonaceous CSU-type.[1] It has arotation period of hours with a brightness variation of in magnitude.[4]
Thisminor planet was named in memory of Swiss mathematicianHugo Hadwiger (1908–1981), professor at theUniversity of Berne for more than 40 years and very popular for his refined art of presentation.[2] The approved naming citation was published by theMinor Planet Center on 22 September 1983 (M.P.C. 8151).[8]
