18126 (2000 OU3) is a large asteroid orbiting between Mars and Jupiter in the main portion of the asteroid belt. NASA JPL has not classified 2000 OU3 as potentially hazardous because its orbit does not bring it close to Earth.
2000 OU3 orbits the sun every 1,700 days (4.65 years), coming as close as 2.28 AU and reaching as far as 3.30 AU from the sun. 2000 OU3 is about 10.3 kilometers in diameter, making it larger than 99% of asteroids, comparable in size to the city of Boston.
The rotation of 2000 OU3 has been observed. It completes a rotation on its axis every 31.35 hours.
2000 OU3's orbit is 1.28 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.
2000 OU3's orbit is determined by observations dating back to May 2, 1976. It was last officially observed on July 5, 2023. The IAU Minor Planet Center records 2,413 observations used to determine its orbit.
