2003 QX113, also written as 2003 QX113, is a detached object[2] that was discovered when it was near aphelion. With an absolute magnitude of 4.7,[3] it may be a dwarf planet.[6]
As of February 2016[update] located 59.9 AU from the Sun,[7] it will have moved beyond 60 AU by 2017 and will reach its aphelion around 2058.[8] It last came to perihelion around 1883.[3] Its current distance makes it one of the twelve most distant known minor planets in the Solar System (see table below).[7]
Size estimate
When 2003 QX113 was first discovered, it was estimated to have an absolute magnitude (H) of 4.9,[1] giving it an assumed size of only 461 kilometres (286 mi) in diameter.[4] As of 2010, 2003 QX113 is estimated to have a brighter absolute magnitude (H) of 4.7.[3] Assuming it is a trans-Neptunian object with a generic albedo of 0.09, it is about 505 kilometres (314 mi) in diameter.[4]
It has been observed 23 times over six oppositions and has an orbit quality of 4.[3]
