1824 Haworth (prov. designation:1952 FM) is anasteroid from the outer region of theasteroid belt, approximately 14 kilometers in diameter. It was discovered on 30 March 1952, by Indiana University'sIndiana Asteroid Program at itsGoethe Link Observatory near Brooklyn, Indiana, United States, and named after physicistLeland John Haworth.[2][4]
Haworth orbits the Sun in theouter main-belt at a distance of 2.8–3.0 AU once every 4 years and 11 months (1,789 days). Its orbit has aneccentricity of 0.04 and aninclination of 2° with respect to theecliptic.[1]
Its firstprecovery was taken atLowell Observatory in 1906, extending the body'sobservation arc by 46 years prior to its official discovery observation at Goethe Link.[4]
It was named in honor of American particle physicistLeland John Haworth (1904–1979), a graduate ofIndiana University and second director of theNational Science Foundation.[2]
His long and varied career included teaching and serving as member of theAtomic Energy Commission, as vice-president and president ofAssociated Universities, Inc., and as director of theBrookhaven National Laboratory. His negotiations were instrumental for the funding of a 4-meter telescope at theCerro Tololo Interamerican Observatory.[2] The officialnaming citation was published by theMinor Planet Center on 18 April 1977 (M.P.C. 4156).[5]
According to the survey carried out by NASA'sWide-field Infrared Survey Explorer with its subsequentNEOWISE mission,Haworth measures 14.17 kilometers in diameter and its surface has analbedo of 0.266.[3] As of 2017, its composition,rotation period and shape remain unknown.
