2010 RE64, also written as 2010 RE64, is a scattered disc object with an absolute magnitude of 4.3.[3] Mike Brown's website lists it as a highly likely dwarf planet.[8]
Preliminary
It has an observation arc of 407 days,[3] and there are currently no known precovery images to help refine its orbit. It is currently 53.7 AU from the Sun.[7] Based on JPL's best-fit solution for the orbit, it reached aphelion around 1829. It is estimated to come to perihelion around 2079.[3]
Assuming a generic trans-Neptunian albedo of 0.09, it is about 612 kilometres (380 mi) in diameter.[5] However, since the true albedo is unknown and it has an absolute magnitude of 4.3,[3] it could easily be from about 370 to 820 km in diameter.[4]
