(303775) 2005 QU182, also written as (303775) 2005 QU182, is a trans-Neptunian object with a bright absolute magnitude of 3.8.[4] Mike Brown lists it as probably a dwarf planet.[7]
Contents
Distance
It came to perihelion in 1971[4] and is currently 50.5 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. Of the known and likely dwarf planets, only Sedna, 2012 VP113 and (445473) 2010 VZ98 have a longer orbit around the Sun.[8]
