Main-belt asteroid
1276 Ucclia (prov. designation 1933 BA ) is a carbonaceousAlauda asteroid from the outer region of theasteroid belt , approximately 31 kilometers (19 miles) in diameter. It was discovered on 24 January 1933 by Belgian astronomerEugène Delporte at theRoyal Observatory of Belgium in Uccle.[ 15] Richard Schorr atBergedorf Observatory in Hamburg, Germany. It was named for the Belgium city ofUccle and its discovering observatory.[ 2]
Orbit and classification [ edit ] Ucclia is a member of theAlauda family (902 [ 4] family of typically bright carbonaceous asteroids named after its parent body,702 Alauda .[ 16] : 23 outer main-belt at a distance of 2.9–3.5 AU once every 5 years and 8 months (2,069 days). Its orbit has aneccentricity of 0.09 and aninclination of 23° with respect to theecliptic .[ 1] precoveries were taken prior to its discovery.[ 15]
Thisminor planet was named afterUccle , in honor of both, the city and the discovering observatory (H 117 [ 2]
Physical characteristics [ edit ] A rotationallightcurve ofUcclia was obtained from photometric observations by Italian and French astronomersSilvano Casulli , Federico Manzini andPierre Antonini in March 2007. It showed a well-definedrotation period of68 magnitude (U=3 [ 13] Adrián Galád atModra Observatory , gave a concurring period ofU=3- [ 11]
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,Ucclia measures between 30.1 and 40.0 kilometers in diameter and its surface has analbedo between 0.05 and 0.14.[ 5] [ 6] [ 7] [ 9] Collaborative Asteroid Lightcurve Link derives an albedo of 0.08 and a diameter of 30.3 kilometers.[ 3]
