21601 (1998 XO89) is a large asteroid that shares Jupiter's orbit around the sun. NASA JPL has not classified 1998 XO89 as potentially hazardous because its orbit does not bring it close to Earth.
1998 XO89 orbits the sun every 4,380 days (11.99 years), coming as close as 5.05 AU and reaching as far as 5.43 AU from the sun. 1998 XO89 is about 54.9 kilometers in diameter, making it larger than 99% of asteroids, comparable in size to the U.S. state of Rhode Island.
The rotation of 1998 XO89 has been observed. It completes a rotation on its axis every 12.65 hours.
1998 XO89's orbit is 4.07 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.
1998 XO89's orbit is determined by observations dating back to March 16, 1991. It was last officially observed on May 9, 2023. The IAU Minor Planet Center records 3,173 observations used to determine its orbit.
