Liyuan is a mid-sized asteroid orbiting between Mars and Jupiter in the main portion of the asteroid belt. NASA JPL has not classified Liyuan as potentially hazardous because its orbit does not bring it close to Earth.
Liyuan orbits the sun every 1,280 days (3.50 years), coming as close as 1.85 AU and reaching as far as 2.75 AU from the sun. Liyuan is about 4.6 kilometers in diameter, making it larger than 99% of asteroids, comparable in size to the San Francisco Bay.
The rotation of Liyuan has been observed. It completes a rotation on its axis every 10.77 hours.
Liyuan's orbit is 0.85 AU from Earth's orbit at its closest point. This means that there is a very 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.
Liyuan's orbit is determined by observations dating back to Oct. 24, 1981. It was last officially observed on Oct. 18, 2022. The IAU Minor Planet Center records 3,358 observations used to determine its orbit.
