13732 Woodall, provisional designation 1998 RC56, is a stony Vestian asteroid from the inner regions of the asteroid belt, approximately 4 kilometers in diameter. It was discovered on 14 September 1998, by the Lincoln Near-Earth Asteroid Research (LINEAR) team at Lincoln Laboratory's Experimental Test Site in Socorro, New Mexico.[7]
The stony S-type asteroid is a member of the Vesta family, which is named after the asteroid 4 Vesta, the second-largest body in the main-belt. It orbits the Sun at a distance of 2.1–2.6 AU once every 3 years and 8 months (1,337 days). Its orbit has an eccentricity of 0.10 and an inclination of 6° with respect to the ecliptic.[1] The first precovery was taken at Siding Spring Observatory in 1989, extending the asteroid's observation arc by 9 years prior to its discovery.[7]
A rotational light-curve was obtained based on photometric observations by Czech astronomer Petr Pravec at the Ondřejov Observatory in September 2009. The light-curve gave a well-defined rotation period of 8.2987±0.0005 hours with a brightness amplitude of 0.27 in magnitude (U=3).[4] The Collaborative Asteroid Lightcurve Link assumes a standard albedo for stony asteroids of 0.20 and calculates a diameter of 3.9 kilometers, based on an absolute magnitude of 14.4.[3]
The minor planet was named after Ashley Renee Woodall (b. 1987) student at the U.S. Austin Academy for Excellence in Garland, Texas. In 2002, she was a finalist of the Discovery Channel Young Scientist Challenge (DCYSC), a science and engineering competition.[2] Naming citation was published on 21 October 2002 (M.P.C. 46767).[8]
