1840 Hus, provisional designation 1971 UY, is a carbonaceous asteroid dwelling the outer regions of the asteroid belt. It was discovered on 26 October 1971 by Czech astronomer Luboš Kohoutek at Bergedorf Observatory in Hamburg, Germany.[6]
It orbits the Sun at a distance of 2.9–3.0 AU once every 5 years (1,821 days). It has a rotation period of 4.780 hours. The asteroid is calculated to measure about 27 kilometers in diameter and to have a geometric albedo of 0.06, as assumed by the Light Curve Database project (LCDB). These figures strongly deviate from observations made by the NEOWISE survey, that indicated the body to be only half the size with a higher albedo of 0.25, which would be rather unusual if it were a C-type asteroid, as assumed by the LCDB project.[3][4]
It is named after Czech Jan Hus (1372–1415), a fifteenth century Bohemian theologian, rector of Charles University in Prague and forerunner of the protestant reformation. He was condemned to death by the Council of Constance and burned at the stake for his reformation ideas.[2] Jan Hus is also known as John Huss in the English speaking world.
