471137 (2010 ET65) is a dwarf planet whose orbit extends beyond the orbit of Neptune. NASA JPL has not classified 2010 ET65 as potentially hazardous because its orbit does not bring it close to Earth.
2010 ET65 orbits the sun every 177,000 days (484.60 years), coming as close as 39.60 AU and reaching as far as 83.78 AU from the sun. Based on its brightness and the way it reflects light, 2010 ET65 is probably between 239.086 to 534.614 kilometers in diameter, making it one of the largest objects, very roughly comparable in size to South Korea.
The rotation of 2010 ET65 has been observed. It completes a rotation on its axis every 7.88 hours.
2010 ET65's orbit is 38.60 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 ET65's orbit is determined by observations dating back to Feb. 7, 2002. It was last officially observed on May 25, 2023. The IAU Minor Planet Center records 457 observations used to determine its orbit.
