(673087) 2015 AJ281 (also designated 2011 FW62) is a magnitude-5.0 trans-Neptunian object that was discovered in 2011.[2] Its orbital elements were very uncertain and it was lost. It was recovered on 6 January 2015 as 2015 AJ281. 2011 FW62 has been identified as a member of the Haumea family in a dynamical study led by Proudfoot and Ragozzine in 2019.[4]
