523591 (2001 QD298) is a large asteroid whose orbit extends beyond the orbit of Neptune. NASA JPL has not classified 2001 QD298 as potentially hazardous because its orbit does not bring it close to Earth.
2001 QD298 orbits the sun every 103,000 days (282.00 years), coming as close as 40.51 AU and reaching as far as 45.39 AU from the sun. Based on its brightness and the way it reflects light, 2001 QD298 is probably between 152.249 to 340.440 kilometers in diameter, making it larger than 99% of asteroids, very roughly comparable in size to the U.S. state of Maryland.
2001 QD298's orbit is 39.50 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.
2001 QD298's orbit is determined by observations dating back to Aug. 28, 2000. It was last officially observed on Sept. 30, 2021. The IAU Minor Planet Center records 99 observations used to determine its orbit.
