469987 (2006 HJ123) is a very large asteroid whose orbit extends beyond the orbit of Neptune. NASA JPL has not classified 2006 HJ123 as potentially hazardous because its orbit does not bring it close to Earth.
2006 HJ123 orbits the sun every 91,300 days (249.97 years), coming as close as 27.51 AU and reaching as far as 51.85 AU from the sun. Based on its brightness and the way it reflects light, 2006 HJ123 is probably between 156.515 to 349.977 kilometers in diameter, making it larger than 99% of asteroids, very roughly comparable in size to the U.S. state of Maryland.
2006 HJ123's orbit is 26.50 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.
2006 HJ123's orbit is determined by observations dating back to April 27, 2006. It was last officially observed on Aug. 8, 2021. The IAU Minor Planet Center records 406 observations used to determine its orbit.
