It was first observed by astronomers at the Mauna Kea Observatories on 24 January 2007.[1][2][4] With a Tisserand's parameter of 1.99, may be considered a member of the damocloids, a dynamical group of minor planets which have comet-like orbits without showing a cometary coma or tail. It orbits the Sun at a distance of 17.7–30.2 AU once every 117 years and 6 months (42,907 days). Its orbit has an eccentricity of 0.26 and an inclination of 65° with respect to the ecliptic. As of July 2017, it is one of 7 known objects with inclination (i) > 60° and perihelion (q) > 15 AU, along with the first discovered {{mpl|2008 KV|42}}.[1] References1. ^http://minorplanetcenter.net/db_search/show_by_properties?perihelion_distance_min=15&inclination_min=60 [2][3][4]2. ^1 2 3 {{cite web |title = 2007 BP102 |work = Minor Planet Center |url = http://www.minorplanetcenter.net/db_search/show_object?object_id=2007+BP102 |accessdate = 14 October 2017}} 3. ^1 2 3 4 {{cite web |title = List of known Trans-Neptunian Objects |publisher = Johnston's Archive |url = http://www.johnstonsarchive.net/astro/tnoslist.html |accessdate = 14 October 2017}} 4. ^1 2 {{cite web |title = List Of Centaurs and Scattered-Disk Objects |work = Minor Planet Center |url = http://www.minorplanetcenter.org/iau/lists/Centaurs.html |accessdate = 14 October 2017}} }} External links
