134210 (2005 PQ21) is a large asteroid whose orbit extends beyond the orbit of Neptune. NASA JPL has not classified 2005 PQ21 as potentially hazardous because its orbit does not bring it close to Earth.
2005 PQ21 orbits the sun every 182,000 days (498.29 years), coming as close as 37.67 AU and reaching as far as 88.13 AU from the sun. Based on its brightness and the way it reflects light, 2005 PQ21 is probably between 88.829 to 198.628 kilometers in diameter, making it larger than 99% of asteroids, very roughly comparable in size to the U.S. state of Delaware.
2005 PQ21's orbit is 36.70 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.
2005 PQ21's orbit is determined by observations dating back to Aug. 21, 2001. It was last officially observed on Oct. 29, 2022. The IAU Minor Planet Center records 139 observations used to determine its orbit.
