“2246 Bowell”的意思、由来-开放百科全书

It 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.^[4]

Physical characteristics

Rotation period

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 {{val|4.992}} hours with a brightness variation of 0.46 in magnitude ({{small|U=3}}).^[9]

Diameter and albedo

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.^[6]^[7]^[8] The Collaborative Asteroid Lightcurve Link agrees with the results obtained by IRAS.^[3]

Naming

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] The official naming citation was published by the Minor Planet Center on 1 January 1981 ({{small|M.P.C. 5688}}).^[34]

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 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 once every 7 years and 10 months (2,876 days).
