18333 (1987 OV) is a large asteroid orbiting between Mars and Jupiter in the main portion of the asteroid belt. NASA JPL has not classified 1987 OV as potentially hazardous because its orbit does not bring it close to Earth.
1987 OV orbits the sun every 1,510 days (4.13 years), coming as close as 2.12 AU and reaching as far as 3.02 AU from the sun. 1987 OV is about 10.1 kilometers in diameter, making it larger than 99% of asteroids, comparable in size to the city of Boston.
1987 OV's orbit is 1.12 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.
1987 OV's orbit is determined by observations dating back to July 19, 1987. It was last officially observed on June 13, 2023. The IAU Minor Planet Center records 2,795 observations used to determine its orbit.
