18140 (2000 OD39) is a mid-sized asteroid orbiting between Mars and Jupiter in the main portion of the asteroid belt. NASA JPL has not classified 2000 OD39 as potentially hazardous because its orbit does not bring it close to Earth.
2000 OD39 orbits the sun every 1,550 days (4.24 years), coming as close as 1.97 AU and reaching as far as 3.28 AU from the sun. 2000 OD39 is about 4.4 kilometers in diameter, making it larger than 99% of asteroids, comparable in size to the island of Manhattan.
The rotation of 2000 OD39 has been observed. It completes a rotation on its axis every 78.28 hours.
2000 OD39's orbit is 0.98 AU from Earth's orbit at its closest point. This means that there is a very 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 OD39's orbit is determined by observations dating back to Sept. 1, 1983. It was last officially observed on March 18, 2023. The IAU Minor Planet Center records 2,257 observations used to determine its orbit.
