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 on 14 December 1979, by American astronomer Edward Bowell at Lowell Observatory's Anderson Mesa Station , and named after the discoverer himself.[2] [4]
Orbit and classification [ edit ]
Bowell 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 .[4]
It orbits the Sun at a distance of 3.6–4.3 AU eccentricity of 0.09 and an inclination of 6° with respect to the ecliptic .[1] precovery was taken at Palomar Observatory in 1955, extending the asteroid's observation arc by 24 years prior to its discovery.[4]
Physical characteristics [ edit ]
Bowell 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 .[10]
Rotation period [ edit ]
A rotational lightcurve of Bowell was obtained during a photometric survey of Hildian asteroids at the Uppsala Astronomical Observatory and others places in the late 1990s. The lightcurve gave a well-defined rotation period of magnitude (U=3 [8]
Diameter and albedo [ edit ]
According to the surveys carried out by the Japanese Akari satellite, the Infrared Astronomical Satellite IRAS (six observations), and NASA's Wide-field Infrared Survey Explorer with its subsequent NEOWISE mission, Bowell measures 40.7, 44.2 and 48.4 kilometers in diameter and its surface has an albedo of 0.066, 0.054 and 0.045, respectively.[5] [6] [7] Collaborative Asteroid Lightcurve Link agrees with the results obtained by IRAS.[3]
This minor planet was named in honor of its discoverer, the American astronomer Edward L. G. Bowell (born 1943), based on a proposal by MPC 's longtime director Brian G. Marsden . Astronomer at the Lowell Observatory and a prolific discoverer of minor planets himself, Bowell has made significant contributions on the observatory's UBV photometry and astrometry programs for minor planets, including the prediction of occultation events.[2] Minor Planet Center on 1 January 1981 (M.P.C. 5688[11]
