21501 Acevedo (provisional designation1998 KC8) is a stony Florianasteroid from the inner regions of theasteroid belt, approximately 2.4 kilometers in diameter.
The asteroid was discovered on 23 May 1998, by theLONEOS team atAnderson Mesa Station in Arizona, United States. It was named for Tony Acevedo, staff member at theArecibo Observatory in Puerto Rico.[2]
Acevedo is a member of theFlora family, one of the largest families ofstony asteroids. It orbits the Sun in theinner main-belt at a distance of 2.1–2.5 AU once every 3 years and 6 months (1,286 days). Its orbit has aneccentricity of 0.07 and aninclination of 6° with respect to theecliptic.[1]
The body'sobservation arc begins almost 20 years prior to its official discovery observation, with aprecovery taken atPalomar Observatory in November 1978.[2]
Acevedo has been characterized as a commonS-type asteroid byPan-STARRS photometric survey.[5]
In August 2013, a fragmentary rotationallightcurve of Acevedo was obtained from photometric observations by astronomers at thePalomar Transient Factory in California. Lightcurve analysis gave a provisionalrotation period of6.5689 hours with a brightness amplitude of 0.10magnitude (U=1).[4]
TheCollaborative Asteroid Lightcurve Link assumes an albedo of 0.24 – which derives from8 Flora, the largest member and namesake of this orbital family – and calculates a diameter of 2.4 kilometers with anabsolute magnitude of 15.25.[3]
Thisminor planet was named in honour of Tony Acevedo (born 1950), staff member at theArecibo Observatory in Puerto Rico, working as multimedia graphic designer and media officer.[2] The approved naming citation was published by theMinor Planet Center on 18 July 2008(M.P.C. 63393).[6]
