434390 (2005 CH81) is a large asteroid whose orbit extends beyond the orbit of Neptune. NASA JPL has not classified 2005 CH81 as potentially hazardous because its orbit does not bring it close to Earth.
2005 CH81 orbits the sun every 149,000 days (407.94 years), coming as close as 37.56 AU and reaching as far as 72.22 AU from the sun. Based on its brightness and the way it reflects light, 2005 CH81 is probably between 62.023 to 138.688 kilometers in diameter, making it larger than 99% of asteroids, very roughly comparable in size to the U.S. state of Delaware.
2005 CH81's orbit is 36.60 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.
2005 CH81's orbit is determined by observations dating back to Feb. 10, 2005. It was last officially observed on April 8, 2022. The IAU Minor Planet Center records 37 observations used to determine its orbit.
