13732 Woodall

13732 Woodall, provisional designation, 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 team at Lincoln Laboratory's Experimental Test Site in Socorro, New Mexico.

Orbit and classification

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. 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 official discovery observation.

Physical characteristics

Woodall has been characterized as a common S-type asteroid by Pan-STARRS photometric survey.
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 hours with a brightness amplitude of in magnitude.
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.

Naming

This minor planet was named after Ashley Renee Woodall 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, a science and engineering competition. The approved naming citation was published by the Minor Planet Center on 21 October 2002.
