Its orbital elements were very uncertain and it was lost. It was recovered on 6 January 2015 as 2015 AJ 281. 2015 AJ 281 has been identified as a member of the Haumea family in a dynamical study led by Proudfoot and Ragozzine in 2019.Modeling the Formation of the Family of the Dwarf Planet Haumea Benjamin Proudfoot Darin Ragozzine The Astronomical Journal May 2019 157 6 230 1904.00038 10.3847/1538-3881/ab19c4 2019AJ....157..230P 90262136 free References (673087) = 2011 FW62 = 2015 AJ281 Minor Planet Center http://www.minorplanetcenter.net/db_search/show_object?object_id=2011+FW62 2012-08-31 2011-05-26 last obs JPL Small-Body Database Browser: (2011 FW62) http://ssd.jpl.nasa.gov/sbdb.cgi?sstr=2011FW62 12 April 2016 How many dwarf planets are there in the outer solar system?
