25108 Boström (provisional designation1998 RV55) is a backgroundasteroid from the central regions of theasteroid belt, approximately 7 kilometers in diameter. It was discovered on 14 September 1998, by astronomers of theLincoln Near-Earth Asteroid Research at theLincoln Laboratory's Experimental Test Site near Socorro, New Mexico, United States. The asteroid was named for 2008-ISEF awardee Johan Ingemar Boström.[2]
Boström is a non-family from the main belt'sbackground population.[3] It orbits the Sun in thecentral asteroid belt at a distance of 2.2–3.1 AU once every 4 years and 3 months (1,563 days;semi-major axis of 2.64 AU). Its orbit has aneccentricity of 0.16 and aninclination of 7° with respect to theecliptic.[1] The body'sobservation arc begins with aprecovery taken by theNear-Earth Asteroid Tracking program atHaleakala Observatory'sGEODSS facility in June 1997, or 9 months prior to its official discovery observation.[2]
According to the survey carried out by theNEOWISE mission of NASA'sWide-field Infrared Survey Explorer, Boström measures 6.812 kilometers in diameter and its surface has an intermediatealbedo of 0.115.[4]
As of 2018, no rotationallightcurve of Boström has been obtained from photometric observations. The body'srotation period,pole and shape remain unknown.[1][5]
Thisminor planet was named after Swedish student Johan Ingemar Boström (born 1989), one of the two team members in the team project who won second place at the 2008Intel International Science and Engineering Fair.[2] The official naming citation was published by theMinor Planet Center on 17 September 2008 (M.P.C. 63877).[6]
