3714 Kenrussell, provisional designation1983 TT1, is a Eunomianasteroid from the central regions of theasteroid belt, approximately 10 kilometers (6 miles) in diameter. It was discovered on 12 October 1983, by American astronomerEdward Bowell at theAnderson Mesa Station near Flagstaff, Arizona, in the United States. It was named for Australian astronomerKenneth S. Russell.[2] The presumablystony asteroid has arotation period of 5.25 hours.[3]
Kenrussell is a member of theEunomia family (502),[3][4] a prominentfamily of stony asteroids and the largest one in the intermediate main belt with more than 5,000 identified members.[9]: 23
It orbits the Sun in thecentral asteroid belt at a distance of 2.1–3.0 AU once every 4 years and 1 month (1,499 days;semi-major axis 2.56 AU). Its orbit has aneccentricity of 0.18 and aninclination of 14° with respect to theecliptic.[1]
The body'sobservation arc begins with its first observation as1973 FK at theCerro El Roble Station in March 1973, more than 10 years prior to its official discovery observation at Anderson Mesa.[2]
Based on its family membership,Kenrussell is an assumed stonyS-type asteroid.[3]
In December 2016, a rotationallightcurve ofKenrussell was obtained from photometric observations by French amateur astronomer Matthieu Conjat . Lightcurve analysis gave a well-definedrotation period of 5.2518 hours with a brightness amplitude of 0.28magnitude (U=3).[8]
According to the survey carried out by theNEOWISE mission of NASA'sWide-field Infrared Survey Explorer,Kenrussell measures 10.440 and 11.260 kilometers in diameter and its surface has analbedo of 0.1189 and 0.1057, respectively.[5][6][7]
TheCollaborative Asteroid Lightcurve Link assumes an albedo of 0.21 – derived from15 Eunomia, the family'sparent body – and calculates a diameter of 8.36 kilometers based on anabsolute magnitude of 12.7.[3]
Thisminor planet was named after Australian astronomerKenneth S. Russell, a long-time operator of the 1.2-metreUK Schmidt Telescope at theSiding Spring Observatory in Australia. He is adiscoverer of minor planets,(17483) and(306376) as well as several periodiccomets including83D/Russell,89P/Russell,91P/Russell and94P/Russell. The official naming citation was published by theMinor Planet Center on 31 May 1988(M.P.C. 13177).[10]
