86366 (1999 XO213) is a large asteroid that orbits between Mars and Jupiter in the outer reaches of the main asteroid belt. NASA JPL has not classified 1999 XO213 as potentially hazardous because its orbit does not bring it close to Earth.
1999 XO213 orbits the sun every 2,860 days (7.83 years), coming as close as 2.95 AU and reaching as far as 4.93 AU from the sun. 1999 XO213 is about 10.1 kilometers in diameter, making it larger than 99% of asteroids, comparable in size to the city of Boston.
1999 XO213's orbit is 1.96 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 XO213's orbit is determined by observations dating back to April 11, 1996. It was last officially observed on March 3, 2023. The IAU Minor Planet Center records 1,301 observations used to determine its orbit.
