It was discovered by American astronomer Edward Bowell at Lowell's U.S. Anderson Mesa Station in Flagstaff, Arizona, on 30 January 1982.The C-type asteroid orbits the Sun at a distance of 2.0–2.8 AU once every 3 years and 8 months (1,338 days). Its orbit shows an eccentricity of 0.17 and is tilted by 3 degrees to the plane of the ecliptic. A photometric light-curve analysis in 2004 rendered a rotation period of 3.16 hours. The Collaborative Asteroid Lightcurve Link assumes a albedo of 0.20, an unusually high value for a carbonaceous body, otherwise known for their low albedos typically around 0.06.The minor planet was named in honor of American astronomer Michael A'Hearn (b. 1940). He was a professor of astronomy at the University of Maryland and a prominent student of cometary physics. He has pursued coordinated spectroscopic and spectrophotometric observations of comets spanning the spectral interval from the vacuum ultraviolet to the radio region. A'Hearn participated in the 1983 discovery with the IUE spacecraft of diatomic sulphur in the spectrum of Comet IRAS–Araki–Alcock and has made many other important contributions to our current understanding of comets."@en }
