305543 (2008 QY40) is a very large asteroid whose orbit extends beyond the orbit of Neptune. NASA JPL has not classified 2008 QY40 as potentially hazardous because its orbit does not bring it close to Earth.
2008 QY40 orbits the sun every 182,000 days (498.29 years), coming as close as 36.81 AU and reaching as far as 89.03 AU from the sun. Based on its brightness and the way it reflects light, 2008 QY40 is probably between 218.049 to 487.573 kilometers in diameter, making it larger than 99% of asteroids, very roughly comparable in size to the U.S. state of West Virginia.
2008 QY40's orbit is 35.80 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.
2008 QY40's orbit is determined by observations dating back to Aug. 25, 2008. It was last officially observed on Nov. 24, 2022. The IAU Minor Planet Center records 266 observations used to determine its orbit.
