38599 (1999 XC210) is a large asteroid that shares Jupiter's orbit around the sun. NASA JPL has not classified 1999 XC210 as potentially hazardous because its orbit does not bring it close to Earth.
1999 XC210 orbits the sun every 4,340 days (11.88 years), coming as close as 4.74 AU and reaching as far as 5.67 AU from the sun. Based on its brightness and the way it reflects light, 1999 XC210 is probably between 10.828 to 24.213 kilometers in diameter, making it larger than 99% of asteroids, very roughly comparable in size to the city of Cleveland, Ohio.
1999 XC210's orbit is 3.77 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 XC210's orbit is determined by observations dating back to Feb. 26, 1989. It was last officially observed on March 28, 2023. The IAU Minor Planet Center records 1,221 observations used to determine its orbit.
