2442 Corbett, provisional designation1980 TO, is a vestoidasteroid from the inner regions of theasteroid belt, approximately 8.5 kilometers in diameter. It was discovered on 3 October 1980, by Czech astronomerZdeňka Vávrová atKleť Observatory, now in the Czech Republic.[8] It is named after British-Indian hunterJim Corbett.[2]
Corbett is aV-type asteroid that orbits the Sun in theinner main-belt at a distance of 2.1–2.7 AU once every 3 years and 8 months (1,348 days). Its orbit has aneccentricity of 0.12 and aninclination of 5° with respect to theecliptic.[1] First identified as1928 RA atHeidelberg in 1928, the body'sobservation arc begins in 1944, when it was identified as1942 GE atTurku Observatory in Finland, 36 years prior to its official discovery observation at Klet.[8]
A rotationallightcurve ofCorbett was obtained from photometric observations by French amateur astronomerRené Roy in July 2009. Lightcurve analysis gave arotation period of 10 hours with a brightness amplitude of 0.12magnitude (U=2).[6]
Photometric observations in the R-band at thePalomar Transient Factory in 2010 and 2013, gave a divergent period of 11.453 (U=2) and 49.507 (U=1) hours with an amplitude of 0.19 and 0.10 magnitude, respectively.[7]
According to the survey carried out by NASA'sWide-field Infrared Survey Explorer with its subsequentNEOWISE mission,Corbett measures 8.327 kilometers in diameter and its surface has analbedo of 0.255,[5] while theCollaborative Asteroid Lightcurve Link assumes a standard albedo of stony asteroids of 0.20 and calculates a diameter of 8.57 kilometers with anabsolute magnitude of 12.7.[3]
Thisminor planet was named in memory of British-IndianJim Corbett (1875–1955), born in Nainital, India. Corbett was a colonel in the British Indian Army and a hunter of man-eating tigers and leopards in India, who became anature conservationist, naturalist and author. He is known for his 1944 hunting biographyMan-Eaters of Kumaon.[2] The approved naming citation was published by theMinor Planet Center on 8 February 1982 (M.P.C. 6650).[9]
