523758 (2014 WJ509) is a very large asteroid whose orbit extends beyond the orbit of Neptune. NASA JPL has not classified 2014 WJ509 as potentially hazardous because its orbit does not bring it close to Earth.
2014 WJ509 orbits the sun every 103,000 days (282.00 years), coming as close as 36.95 AU and reaching as far as 48.81 AU from the sun. Based on its brightness and the way it reflects light, 2014 WJ509 is probably between 196.135 to 438.571 kilometers in diameter, making it larger than 99% of asteroids, very roughly comparable in size to the U.S. state of West Virginia.
2014 WJ509's orbit is 36.00 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.
2014 WJ509's orbit is determined by observations dating back to May 6, 2010. It was last officially observed on March 25, 2023. The IAU Minor Planet Center records 173 observations used to determine its orbit.
