taxonomic scheme. It orbits the Sun at a distance of 1.9–3.0
AU once every 3 years and 10 months (1,407 days). Its orbit has an
eccentricity of 0.21 and an
inclination of 25
° with respect to the
ecliptic.
Measurements using the
adaptive optics at the
W. M. Keck Observatory give a diameter estimate of 76 km. The size ratio between the major and minor axes is 1.16.
During 2004, the asteroid was observed
occulting a star. The resulting
chords were used to determine a diameter estimate of 91.2 km. This is a poor match to the diameter determined by other means.
