2006 QH181, also written as 2006 QH181, is a trans-Neptunian object (TNO). It is very likely a dwarf planet,[8] and is part of the scattered disc.[2][3] It's orbit is currently too poorly determined (U=6)[4] to know whether there is a resonance with Neptune.

Distance

It came to perihelion around 1858.[4] It is currently 82.9 AU from the Sun[7][9] and moving at 2.8 kilometers per second (6,300 miles per hour) with respect to the Sun.[9] The only dwarf planets and likely dwarf planets currently farther from the Sun are V774104, Eris (96.4 AU),[10] 2007 OR10 (87.0 AU),[11] Sedna (86.3 AU),[12] and 2012 VP113 (83.1 AU). Because it is so far from the Sun, it only has an apparent magnitude of 23.6.[7]

Including all known objects currently located at least twice as far as Neptune.[13]

Orbit

It has been observed 15 times over only three oppositions and thus currently has a somewhat poorly known orbit. JPL ranks orbital quality from 0 to 9 (0 being best), and 2006 QH181 is currently listed with an orbit quality of 6.[4][14]
