119473 (2001 UO18) is a large asteroid whose orbit extends beyond the orbit of Neptune. NASA JPL has not classified 2001 UO18 as potentially hazardous because its orbit does not bring it close to Earth.
2001 UO18 orbits the sun every 91,000 days (249.14 years), coming as close as 28.31 AU and reaching as far as 50.85 AU from the sun. Based on its brightness and the way it reflects light, 2001 UO18 is probably between 62.886 to 140.618 kilometers in diameter, making it larger than 99% of asteroids, very roughly comparable in size to the U.S. state of Delaware.
2001 UO18's orbit is 27.30 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 UO18's orbit is determined by observations dating back to Oct. 19, 2001. It was last officially observed on Jan. 22, 2020. The IAU Minor Planet Center records 98 observations used to determine its orbit.
