524366 (2001 XR254) is a very large asteroid whose orbit extends beyond the orbit of Neptune. NASA JPL has not classified 2001 XR254 as potentially hazardous because its orbit does not bring it close to Earth.
2001 XR254 orbits the sun every 102,000 days (279.26 years), coming as close as 41.36 AU and reaching as far as 44.24 AU from the sun. Based on its brightness and the way it reflects light, 2001 XR254 is probably between 183.044 to 409.298 kilometers in diameter, making it larger than 99% of asteroids, very roughly comparable in size to the U.S. state of Maryland.
2001 XR254's orbit is 40.30 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 XR254's orbit is determined by observations dating back to Dec. 10, 2001. It was last officially observed on March 1, 2022. The IAU Minor Planet Center records 130 observations used to determine its orbit.
