    (182294) 2001 KU76 (provisional designation 2001 KU76) is a trans-Neptunian object (TNO) that has a possible 6:11 resonance with Neptune. [2] [3]

    Contents

    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] 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]
