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