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.
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. The first precovery was taken at Siding Spring Observatory in 1989, extending the asteroid's observation arc by 9 years prior to its discovery.
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 7000829870000000000♠8.2987±0.0005 hours with a brightness amplitude of 6999270000000000000♠0.27 in magnitude (U=3). 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.
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. Naming citation was published on 21 October 2002 (M.P.C. 46767).
