2009 JX18 is a large asteroid whose orbit extends beyond the orbit of Neptune. NASA JPL has not classified 2009 JX18 as potentially hazardous because its orbit does not bring it close to Earth.
2009 JX18 orbits the sun every 84,200 days (230.53 years), coming as close as 20.17 AU and reaching as far as 55.01 AU from the sun. Based on its brightness and the way it reflects light, 2009 JX18 is probably between 28.612 to 63.979 kilometers in diameter, making it larger than 99% of asteroids, very roughly comparable in size to the city of Houston.
2009 JX18's orbit is 19.20 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.
2009 JX18's orbit is determined by observations dating back to May 14, 2009. It was last officially observed on May 25, 2009. The IAU Minor Planet Center records 8 observations used to determine its orbit.
