(182294) 2001 KU76 (provisional designation 2001 KU76) is a trans-Neptunian object (TNO) that has a possible 6:11 resonance with Neptune.[2][3]
Assuming a generic TNO albedo of 0.09, it is about 211 km in diameter.[5] The assumed diameter of this object makes it a possible dwarf planet.[6]
Resonance
Simulations by Lykawka in 2007 show that 2001 KU76 may be librating in the 6:11 resonance with Neptune.[2] Buie classifies it as probably in resonance, although some possible orbits do not librate.[3] 2001 KU76 has a semi-major axis of 45 AU and an orbital period of about 302 years.[1]
It has been observed 29 times over 6 years and has an orbit quality code of 4.[1]
