21501 Acevedo, provisional designation 1998 KC8, is a stony Flora asteroid from the inner regions of the asteroid belt, approximately 2.4 kilometers in diameter. It was discovered on 23 May 1998, by the U.S. Lowell Observatory Near-Earth Object Search (LONEOS) team at Anderson Mesa Station, Arizona.[2]
The S-type asteroid is a member of the Flora family, one of the largest groups of stony asteroids in the main-belt. It orbits the Sun at a distance of 2.1–2.5 AU once every 3 years and 6 months (1,286 days). Its orbit has an eccentricity of 0.07 and an inclination of 6° with respect to the ecliptic.[1] The first precovery was taken at Palomar Observatory in 1978, extending the asteroid's observation arc by 20 years prior to its discovery.[2]
A fragmentary rotational light-curve of this asteroid was obtained from photometric observations made at the U.S. Palomar Transient Factory in August 2013. The light-curve gave a provisional rotation period of 6.5689±0.0050 hours with a brightness amplitude of 0.10 in magnitude (U=1).[4] The Collaborative Asteroid Lightcurve Link assumes an albedo of 0.24 – which derives from 8 Flora, the largest member and namesake of this orbital family – and calculates a diameter of 2.4 kilometers.[3]
The minor planet was named in honour of Tony Acevedo (b. 1950), staff member at the Arecibo Observatory in Puerto Rico, working as multimedia graphic designer and media officer.[2] Naming citation was published on 18 July 2008 (M.P.C. 63393).[6]
