(86047) 1999 OY3 (provisional designation 1999 OY3) is a trans-Neptunian object that resides in the Kuiper belt beyond Pluto. It was discovered on July 18, 1999, at the Mauna Kea Observatory, Hawaii, USA.

Origin

Main article: Haumea family

1999 OY3 is a candidate member of the Haumea family and, as a result, may have a high albedo.[8]

Of the currently known Haumea-family members, 2009 OY3 has the dimmest absolute magnitude (H) of the group at 6.8, suggesting that it is also the smallest member of the group.
