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]
Woodall is a member of the Vesta family, which is named after 4 Vesta, the second-largest asteroid in the main-belt. It orbits the Sun in the inner main-belt at a distance of 2.1–2.6 AU once every 3 years and 8 months (1,336 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 official discovery observation. [7]
Woodall has been characterized as a common S-type asteroid by Pan-STARRS photometric survey. [5]
A rotational lightcurve was obtained based on photometric observations by Czech astronomer Petr Pravec at the Ondřejov Observatory in September 2009. Lightcurve analysis gave a well-defined rotation period of 8.2987 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 with an absolute magnitude of 14.4. [3]
This minor 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 the Discovery Channel Young Scientist Challenge ( DCYSC), a science and engineering competition. [2] The approved naming citation was published by the Minor Planet Center on 21 October 2002 ( M.P.C. 46767). [8]
