129746 (1999 CE119) is a large asteroid whose orbit extends beyond the orbit of Neptune. NASA JPL has not classified 1999 CE119 as potentially hazardous because its orbit does not bring it close to Earth.
1999 CE119 orbits the sun every 90,100 days (246.68 years), coming as close as 28.79 AU and reaching as far as 49.87 AU from the sun. Based on its brightness and the way it reflects light, 1999 CE119 is probably between 56.566 to 126.485 kilometers in diameter, making it larger than 99% of asteroids, very roughly comparable in size to the U.S. state of Delaware.
1999 CE119's orbit is 27.80 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.
1999 CE119's orbit is determined by observations dating back to Feb. 10, 1999. It was last officially observed on June 24, 2020. The IAU Minor Planet Center records 138 observations used to determine its orbit.
