13813 (1998 YX) is a large asteroid orbiting between Mars and Jupiter in the main portion of the asteroid belt. NASA JPL has not classified 1998 YX as potentially hazardous because its orbit does not bring it close to Earth.
1998 YX orbits the sun every 1,910 days (5.23 years), coming as close as 2.74 AU and reaching as far as 3.27 AU from the sun. Based on its brightness and the way it reflects light, 1998 YX is probably between 8.176 to 18.283 kilometers in diameter, making it larger than 99% of asteroids, very roughly comparable in size to the city of Boston.
The rotation of 1998 YX has been observed. It completes a rotation on its axis every 5.40 hours.
1998 YX's orbit is 1.77 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.
1998 YX's orbit is determined by observations dating back to Dec. 22, 1982. It was last officially observed on July 1, 2023. The IAU Minor Planet Center records 2,801 observations used to determine its orbit.
