1897 Hind, provisional designation1971 UE1, is a Florianasteroid from the inner regions of theasteroid belt, approximately 5 kilometers in diameter. It was discovered on 26 October 1971, by Czech astronomerLuboš Kohoutek atBergedorf Observatory in Hamburg, Germany.[9] The asteroid was named after English astronomerJohn Russell Hind.[2]
Hind is a member of theFlora family, one of the largest groups of stony asteroids in the main-belt. It orbits the Sun in theinner main-belt at a distance of 2.0–2.6 AU once every 3 years and 5 months (1,260 days). Its orbit has aneccentricity of 0.14 and aninclination of 4° with respect to theecliptic.[1]
A firstprecovery was taken atPalomar Observatory in 1956, extending the asteroid'sobservation arc by 15 years prior to its discovery.[9]
Hind has been characterized as a stonyS-type asteroid.[3]
According to the survey carried out by theNEOWISE mission of NASA'sWide-field Infrared Survey Explorer,Hind measures 5.0 kilometers in diameter and its surface has analbedo of 0.307,[4][5] while theCollaborative Asteroid Lightcurve Link assumes a standard albedo of 0.24 – derived from8 Flora, the family's largest member and namesake – and calculates a diameter of 5.7 kilometers with anabsolute magnitude of 13.4.[3]
In July 2005,Hind had originally been identified as a relativelyfast rotator, as photometric observations by astronomersReiner Stoss,Jaime Nomen,Salvador Sanchez andRaoul Behrend gave arotation period of0.82±0.01 hours, or less than 50 minutes (U=1).[6] However, the lightcurve was only fragmentary. In August 2012, it was superseded with more accurate observation at the Australian Riverland Dingo Observatory that gave a slower period of2.6336±0.0001 hours with a brightness variation of 0.09 inmagnitude (U=2).[7]
Thisminor planet was named after English astronomerJohn Russell Hind (1823–1895),discoverer of ten minor planets including7 Iris and8 Flora, the namesake of the family the asteroid belongs to. Hind worked for many years atGeorge Bishop's Observatory near London where he made his discoveries. He was also superintendent of the BritishNautical Almanac Office in the second half of the 19th century.[2] The officialnaming citation was published by theMinor Planet Center on 1 June 1975 (M.P.C. 3827).[10]
