1452 Hunnia, provisional designation1938 DZ1, is a carbonaceous Meliboeanasteroid from the outer regions of theasteroid belt, approximately 20 kilometers in diameter. It was discovered on 26 February 1938, by Hungarian astronomerGyörgy Kulin at theKonkoly Observatory in Budapest.[11] The asteroid was named in honor of theHungarian nation.[3]
Hunnia is a member of theMeliboea family (604),[5] a smallerasteroid family of a few hundred carbonaceousouter-belt asteroids, named after137 Meliboea.[12]: 23 It orbits the Sun at a distance of 2.5–3.7 AU once every 5 years and 6 months (2,003 days). Its orbit has aneccentricity of 0.20 and aninclination of 14° with respect to theecliptic.[1]
The body'sobservation arc begins atGoethe Link Observatory in March 1949, more than 11 years after its official discovery observation at Konkoly.[11] (The large time span withoutastrometric follow-up observations coincides with the period ofWWII.)
Hunnia is an assumed carbonaceousC-type asteroid,[4] in agreement with the overallspectral type of theMeliboea family.[12]: 23
Between February and March 1998, a rotationallightcurve ofHunnia was obtained from photometric observations by Hungarian astronomersKrisztián Sárneczky,Gyula Szabó andLászló Kiss. Lightcurve analysis gave arotation period of 17.2 hours with a brightness amplitude of 0.34magnitude (U=2).[10] No other lightcurves have since been obtained.[4]
According to the survey carried out by theNEOWISE mission of NASA'sWide-field Infrared Survey Explorer,Hunnia measures between 18.76 and 20.910 kilometers in diameter and its surface has analbedo between 0.0435 and 0.06.[6][7][8][9]
TheCollaborative Asteroid Lightcurve Link assumes a standard albedo for carbonaceous asteroids of 0.057 and calculates a diameter of 21.16 kilometers based on anabsolute magnitude of 12.1.[4]
Thisminor planet was named in honor of theHungarian nation.[3] Also known as Magyars, the Hungarians are believed to be ofHunnic heritage. The officialnaming citation was published by theMinor Planet Center on 1 February 1980 (M.P.C. 5182).[13]
