2839 Annette, provisional designation 1929 TP, is a main-belt asteroid, discovered by Clyde Tombaugh during his search for Pluto at the Lowell Observatory, Flagstaff, on October 5, 1929.[1]
Photometric observations of the asteroid during 2005 at the Palmer Divide Observatory in Colorado Springs, Colorado, were used to generate a light curve with a period of 10.457 ± 0.003 hours and a variation in brightness of 0.92 ± 0.03 magnitude.[3]
The asteroid was named after Clyde Tombaugh's daughter, Annette.[2]
