13732 Woodall, provisional designation1998 RC56, is a stony Vestianasteroid from the inner regions of theasteroid belt, approximately 4 kilometers in diameter. It was discovered on 14 September 1998, by theLincoln Near-Earth Asteroid Research (LINEAR) team atLincoln Laboratory's Experimental Test Site in Socorro, New Mexico.[7]
Woodall is a member of theVesta family, which is named after4 Vesta, the second-largest asteroid in the main-belt. It orbits the Sun in theinner main-belt at a distance of 2.1–2.6 AU once every 3 years and 8 months (1,336 days). Its orbit has aneccentricity of 0.10 and aninclination of 6° with respect to theecliptic.[1] The firstprecovery was taken atSiding Spring Observatory in 1989, extending the asteroid'sobservation arc by 9 years prior to its official discovery observation.[7]
Woodall has been characterized as a commonS-type asteroid byPan-STARRS photometric survey.[5]
A rotationallightcurve was obtained based onphotometric observations by Czech astronomerPetr Pravec at theOndřejov Observatory in September 2009. Lightcurve analysis gave a well-definedrotation period of8.2987 hours with a brightness amplitude of0.27 inmagnitude (U=3).[4]
TheCollaborative Asteroid Lightcurve Link assumes a standard albedo forstony asteroids of 0.20 and calculates a diameter of 3.9 kilometers with anabsolute magnitude of 14.4.[3]
Thisminor planet was named after Ashley Renee Woodall (born 1987) student at the U.S. Austin Academy for Excellence in Garland, Texas. In 2002, she was a finalist of theDiscovery Channel Young Scientist Challenge (DCYSC), a science and engineering competition.[2] The approved naming citation was published by theMinor Planet Center on 21 October 2002 (M.P.C. 46767).[8]
