13003 Dickbeasley, provisional designation1982 FN, is a backgroundasteroid from the central region of theasteroid belt, approximately 6 kilometers in diameter. It was discovered by American astronomerEdward Bowell at Lowell'sAnderson Mesa Station on 21 March 1982.[2] The asteroid was named in memory of AmericanNAU administratorDick Beasley.[2]
Dickbeasley is a non-family asteroid from the main belt'sbackground population. It orbits the Sun in thecentral main-belt at a distance of 2.0–3.1 AU once every 4 years and 1 month (1,495 days). Its orbit has aneccentricity of 0.21 and aninclination of 27° with respect to theecliptic.[1] The body'sobservation arc begins with its official discovery observation, as noprecoveries were taken, and no prior identifications were made.[2]
Thisminor planet was named in memory of American Richard "Dick" E. Beasley (1934–1992), a teacher and administrator atNorthern Arizona University. He was also a multi-media artist and a preeminent figure in thecalligraphic world.[2] The approved naming citation was published by theMinor Planet Center on 9 February 2009 (M.P.C. 65122).[10]
In April 2015, a rotationallightcurve ofDickbeasley was obtained from photometric observations made at the Phillips Academy Observatory (I12). It gave arotation period of3.502 hours with a brightness variation of 0.44magnitude (U=3-).[8] One month later, in May 2015, observations atTexas Tech's Preston Gott Observatory gave a concurring period of3.4999 hours with an amplitude of 0.30 magnitude (U=3-).[7]
These results supersede the first obtained lightcurve at thePalomar Transient Factory from September 2012, which gave a period of3.4992 hours and an amplitude of 0.42 (U=2).[6]
According to the surveys carried out by theNEOWISE mission of NASA's space-basedWide-field Infrared Survey Explorer,Dickbeasley measures 8.2 kilometers in diameter and its surface has analbedo of 0.07,[4][5] while heCollaborative Asteroid Lightcurve Link assumes a standard albedo forstony asteroids of 0.20 and calculates a diameter of 5.4 kilometers with anabsolute magnitude of 13.7.[3]
