103067 (1999 XA143) is a mid-sized asteroid whose orbit crosses the orbit of Earth. NASA JPL has classified 1999 XA143 as a "Potentially Hazardous Asteroid" due to its predicted close pass(es) with Earth.
1999 XA143 orbits the sun every 914 days (2.50 years), coming as close as 0.77 AU and reaching as far as 2.92 AU from the sun. 1999 XA143 is about 1.3 kilometers in diameter, making it larger than 99% of asteroids, comparable in size to the U.S. Pentagon.
The rotation of 1999 XA143 has been observed. It completes a rotation on its axis every 9.85 hours.
1999 XA143's orbit is 0.04 AU from Earth's orbit at its closest point. This means that there is a 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 XA143's orbit is determined by observations dating back to Dec. 2, 1994. It was last officially observed on Nov. 1, 2021. The IAU Minor Planet Center records 984 observations used to determine its orbit.
