11221 (1999 JO26) 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 JO26 as potentially hazardous because its orbit does not bring it close to Earth.
1999 JO26 orbits the sun every 2,110 days (5.78 years), coming as close as 2.86 AU and reaching as far as 3.57 AU from the sun. 1999 JO26 is about 21.6 kilometers in diameter, making it larger than 99% of asteroids, comparable in size to the city of Indianapolis.
The rotation of 1999 JO26 has been observed. It completes a rotation on its axis every 15.80 hours.
1999 JO26's orbit is 1.88 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 JO26's orbit is determined by observations dating back to May 2, 1976. It was last officially observed on July 1, 2023. The IAU Minor Planet Center records 4,512 observations used to determine its orbit.
