(182294) 2001 KU76, provisionally known as 2001 KU76, is a trans-Neptunian object (TNO) that has a 6:11 resonance with Neptune. This is the same resonance that dwarf planet Makemake is either near or in.
It will come to perihelion in 2021.
Assuming a generic TNO albedo of 0.09, it is about 211 km in diameter. The assumed diameter of this object makes it a possible dwarf planet.
Resonance
Simulations by Lykawka in 2007 show that (182294) 2001 KU76 is librating in the 11:6 resonance with Neptune. This is the same resonance that dwarf planet Makemake is either near or in. Both objects have a semi-major axis of 45 AU and an orbital period of about 302 years.
It has been observed 29 times over 6 years and has an orbit quality code of 4.
