2246 Bowell, provisional designation 1979 XH, is a rare-type Hildian asteroid from the outermost region of the asteroid belt, approximately 44 kilometers in diameter. It was discovered by American astronomer Edward Bowell at Lowell Observatory's Anderson Mesa Station on 14 December 1979.
The asteroid is a member of the Hilda family, the outermost orbital group of asteroids in the main-belt, that are in a 3:2 orbital resonance with Jupiter. It has a reddish D-type spectrum on both the SMASS and Tholen taxonomic scheme, and is one of only 46 known bodies with such a spectral type.
Bowell orbits the Sun at a distance of 3.6–4.3 AU once every 7 years and 10 months (2,876 days). Its orbit has an eccentricity of 0.09 and an inclination of 6° with respect to the ecliptic. The first used precovery was taken at Palomar Observatory in 1955, extending the asteroid's observation arc by 24 years prior to its discovery.
A rotational light-curve for this body was obtained during a photometric survey of Hildian asteroids at the Uppsala Astronomical Observatory and others places in the late 1990s. The light-curve gave a well-defined rotation period of 4.992 hours with a brightness variation of 0.46 in magnitude (U=3).
