Resonance
Simulations by Lykawka in 2007 show that 2001 KU76 may be librating in the 6:11 resonance with Neptune.[2] Marc 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]
