84882 Table Mountain, provisional designation 2003 CN16, is a bright asteroid from the central region of the asteroid belt, approximately 5 kilometers in diameter. It was discovered on 1 February 2003, by American astronomer James Whitney Young at the Table Mountain Observatory near Wrightwood, California. The asteroid was later named after the discovering observatory.
Table Mountain orbits the Sun in the central main-belt at a distance of 1.9–3.4 AU once every 4 years and 3 months (1,565 days). Its orbit has an eccentricity of 0.29 and an inclination of 14° with respect to the ecliptic. It was first identified as 1997 UB9 at Lincoln Laboratory's Experimental Test Site in 1997, extending the asteroid's observation arc by 6 years prior to its official discovery observation.
According to the survey carried out by the NEOWISE mission of NASA's Wide-field Infrared Survey Explorer, Table Mountain measures 3.0 kilometers in diameter and its surface has a high albedo of 0.306. The asteroid's generic diameter measures between 3 and 7 kilometers, based on an assumed albedo in the range of 0.05–0.25 and an absolute magnitude of 14.7.
As of 2017, the asteroid's composition, rotation period and shape remain unknown.
