1897 Hind, provisional designation 1971 UE1, is a smaller asteroid from the inner regions of the asteroid belt about 5 kilometers in diameter. It was discovered by Czech astronomer Luboš Kohoutek at Bergedorf Observatory in Hamburg, Germany on 26 October 1971.[7]
The stony S-type asteroid orbits the Sun at a distance of 2.0–2.6 AU once every 3.45 years (1,260 days).[1] It belongs to the Flora family of stony asteroids, one of the larger groups known to dwell in the inner-main belt.[3]
Hind had been provisionally identified as a very fast rotator, with a rotation period of less than 50 minutes.[6] However, a more recent analysis from 2012 at the Australian Riverland Dingo Observatory by the Collaborative Asteroid Lightcurve Link (CALL) measured a slower period of 2.6 hours.[5]
It was named after English astronomer John Russell Hind (1823–1895), discoverer of ten minor planets including 7 Iris and 8 Flora, the namesake of the family the asteroid belongs to. Hind worked for many years at George Bishop's Observatory near London where he made his discoveries. He also served as superintendent of the British Nautical Almanac Office in the second half of the 19th century.[2]
