523639 (2010 RE64) is a dwarf planet whose orbit extends beyond the orbit of Neptune. NASA JPL has not classified 2010 RE64 as potentially hazardous because its orbit does not bring it close to Earth.
2010 RE64 orbits the sun every 199,000 days (544.83 years), coming as close as 36.54 AU and reaching as far as 96.70 AU from the sun. Based on its brightness and the way it reflects light, 2010 RE64 is probably between 368.600 to 824.214 kilometers in diameter, making it one of the largest objects, very roughly comparable in size to Great Britain.
2010 RE64's orbit is 35.60 AU from Earth's orbit at its closest point. This means that there is an extremely wide berth between this asteroid and Earth at all times.
Orbital simulations conducted by NASA JPL's CNEOS do not show any close approaches to Earth.
2010 RE64's orbit is determined by observations dating back to July 11, 2010. It was last officially observed on Nov. 23, 2022. The IAU Minor Planet Center records 199 observations used to determine its orbit.
