525460 (2005 EX297) is a large asteroid whose orbit extends beyond the orbit of Neptune. NASA JPL has not classified 2005 EX297 as potentially hazardous because its orbit does not bring it close to Earth.
2005 EX297 orbits the sun every 106,000 days (290.21 years), coming as close as 38.99 AU and reaching as far as 48.63 AU from the sun. Based on its brightness and the way it reflects light, 2005 EX297 is probably between 140.785 to 314.804 kilometers in diameter, making it larger than 99% of asteroids, very roughly comparable in size to the U.S. state of Maryland.
2005 EX297's orbit is 38.00 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 EX297's orbit is determined by observations dating back to March 11, 2005. It was last officially observed on Feb. 26, 2022. The IAU Minor Planet Center records 76 observations used to determine its orbit.
