Carbonaceous background asteroid
1444 Pannonia (prov. designation 1938 AE ) is a carbonaceousbackground asteroid from the outer region of theasteroid belt , approximately 29 kilometers (18 miles) in diameter. It was discovered on 6 January 1938, by Hungarian astronomerGyörgy Kulin atKonkoly Observatory in Budapest, Hungary.[ 17] Pannonia .[ 3]
Orbit and classification [ edit ] Pannonia is a non-family asteroid of the main belt'sbackground population when applying thehierarchical clustering method to itsproper orbital elements . It orbits the Sun at a distance of 2.7–3.6 AU once every 5 years and 7 months (2,044 days). Its orbit has aneccentricity of 0.14 and aninclination of 18° with respect to theecliptic .[ 1] Pannonia ' sobservation arc begins 3 weeks after its official discovery at Konkoly, as noprecoveries were taken, and no prior identifications were made.[ 17]
Thisminor planet was named forPannonia , an ancient province of theRoman Empire , which was partially located over the territory of the present-day westernHungary .[ 3] naming citation was published by theMinor Planet Center on 1 February 1980 (M.P.C. 5183[ 18]
Physical characteristics [ edit ] In April 2001, astronomer Colin Bembrick obtained the first rotationallightcurve ofPannonia at Tarana Observatory (431 rotation period of 10.756 hours with a brightness amplitude of 0.16magnitude (U=3 [ 14] Laurent Bernasconi andBernard Christophe Additional periods of 6.2 and 6.205 hours with an amplitude of 0.57 and 0.37, respectively (U=2-/2 [ 13]
Diameter and albedo [ edit ] According to the surveys carried out by the Infrared Astronomical SatelliteIRAS , the JapaneseAkari satellite, and NASA'sWide-field Infrared Survey Explorer with its subsequentNEOWISE mission,Pannonia measures between 26.36 and 31.49 kilometers in diameter, and its surface has analbedo between 0.04 and 0.47.[ 5] [ 8] [ 9] [ 10] [ 11] [ 12] Collaborative Asteroid Lightcurve Link derives an albedo of 0.0501 and a diameter of 27.14 kilometers with anabsolute magnitude of 11.7.[ 4]
