Carbonaceous Meliboean asteroid
1452 Hunnia , provisional designation 1938 DZ1 , is a carbonaceous Meliboean asteroid from the outer regions of the asteroid belt , approximately 20 kilometers in diameter. It was discovered on 26 February 1938, by Hungarian astronomer György Kulin at the Konkoly Observatory in Budapest.[ 11] Hungarian nation .[ 3]
Orbit and classification
Hunnia is a member of the Meliboea family (604 [ 5] asteroid family of a few hundred carbonaceous outer -belt asteroids, named after 137 Meliboea .[ 12] : 23 AU once every 5 years and 6 months (2,003 days). Its orbit has an eccentricity of 0.20 and an inclination of 14° with respect to the ecliptic .[ 1]
The body's observation arc begins at Goethe Link Observatory in March 1949, more than 11 years after its official discovery observation at Konkoly.[ 11] astrometric follow-up observations coincides with the period of WWII .)
Physical characteristics
Hunnia is an assumed carbonaceous C-type asteroid ,[ 4] spectral type of the Meliboea family .[ 12] : 23
Rotation period
Between February and March 1998, a rotational lightcurve of Hunnia was obtained from photometric observations by Hungarian astronomers Krisztián Sárneczky , Gyula Szabó and László Kiss . Lightcurve analysis gave a rotation period of 17.2 hours with a brightness amplitude of 0.34 magnitude (U=2 [ 10] [ 4]
Diameter and albedo
According to the survey carried out by the NEOWISE mission of NASA's Wide-field Infrared Survey Explorer , Hunnia measures between 18.76 and 20.910 kilometers in diameter and its surface has an albedo between 0.0435 and 0.06.[ 6] [ 7] [ 8] [ 9]
The Collaborative Asteroid Lightcurve Link assumes a standard albedo for carbonaceous asteroids of 0.057 and calculates a diameter of 21.16 kilometers based on an absolute magnitude of 12.1.[ 4]
Naming
This minor planet was named in honor of the Hungarian nation .[ 3] Hunnic heritage. The official naming citation was published by the Minor Planet Center on 1 February 1980 (M.P.C. 5182[ 13]
