2011 FW62

2011 FW62, also designated 2015 AJ281, is a trans-Neptunian object that was discovered in 2011. With an absolute magnitude of 5.0,[2] it is possibly a dwarf planet.[3] 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]
