rotation period of 10.5 hours and measures approximately 5 kilometers (3.1 miles) in diameter. It was named after the discoverer's daughter.[2]

Orbit and classification

Annette is a S-type asteroid and member of the Flora family, one of the largest families of stony asteroids. It orbits the Sun in the inner main-belt at a distance of 1.9–2.5 AU once every 3 years and 4 months (1,205 days). Its orbit has an eccentricity of 0.15 and an inclination of 5° with respect to the ecliptic.[1] Due to a precovery taken at Lowell Observatory, the body's observation arc was extended by 4 days prior to its official discovery observation.[9]

Diameter and albedo

According to the survey carried out by NASA's

albedo between 0.056 and 0.47,[4][5][6] while the Collaborative Asteroid Lightcurve Link assumes an albedo of 0.24 – derived from 8 Flora, the largest member and namesake of its family – and calculates a diameter of 3.66 kilometers using Robert Buchheim's fainter absolute magnitude of 14.35.[3]
