(16882) 1998 BO13 (provisional designation1998 BO13) is a dark Zhongguoasteroid from thebackground population in the outermost region of theasteroid belt, approximately 10 kilometers (6 miles) in diameter. It was discovered on 24 January 1998, by astronomers with theLincoln Near-Earth Asteroid Research at theLincoln Laboratory's Experimental Test Site near Socorro, New Mexico, in the United States.[1]
1998 BO13 is a non-family asteroid from the main belt'sbackground population,[6] and a member of the small group ofZhongguo asteroids,[3] located in theHecuba gap and locked in a 2:1mean-motion resonance with the gas giantJupiter. Contrary to the nearbyGriqua group, the orbits of the Zhongguos are stable over half a billion years.[3] According to Milani and Knežević, this asteroid is a core member of the unnamed asteroid family formed by the Zhongguo asteroid(11097) 1994 UD1.[4]
It orbits the Sun in theouter main-belt at a distance of 2.7–3.9 AU once every 6.02 years (2,199 days;semi-major axis of 3.31 AU). Its orbit has aneccentricity of 0.19 and aninclination of 1° with respect to theecliptic.[2]
The body'sobservation arc begins with aprecovery taken bySpacewatch in November 1996, or 14 months prior to its official discovery observation at Socorro.[1]
1998 BO13 has anabsolute magnitude of 13.5.[2] As of 2018, no rotationallightcurve for this asteroid has been obtained fromphotometric observations. The body'srotation period,pole and shape remain unknown.[2]
According to the survey carried out by theNEOWISE mission of NASA'sWide-field Infrared Survey Explorer, measures 9.827 kilometers in diameter and its surface has analbedo of 0.061,[5] which is rather typical for the abundant carbonaceousC-type asteroids in the outer main-belt.
Thisminor planet was numbered by theMinor Planet Center on 13 September 2000, after its orbit had sufficiently been secured (M.P.C. 41165).[7] As of 2018, it has not beennamed.[1]
