    Distance

    It came to perihelion in 1971 [4] and is currently 51.8  AU from the Sun. [6] In April 2013, it moved beyond 50 AU from the Sun.

    It has been observed 81 times over 10 oppositions with precovery images back to 1974. [4]

    2005 QU182 takes over 1,200 years to orbit the Sun. Among large TNOs, only Sedna, 2012 VP113, 2013 FS28 and (445473) 2010 VZ98 have a longer orbit around the Sun. 2005QU182-orbit.png
