111231 (2001 WM60) is a mid-sized asteroid that shares Jupiter's orbit around the sun. NASA JPL has not classified 2001 WM60 as potentially hazardous because its orbit does not bring it close to Earth.
2001 WM60 orbits the sun every 4,450 days (12.18 years), coming as close as 4.96 AU and reaching as far as 5.64 AU from the sun. Based on its brightness and the way it reflects light, 2001 WM60 is probably between 5.951 to 13.306 kilometers in diameter, making it larger than 99% of asteroids, very roughly comparable in size to the San Francisco Bay.
The rotation of 2001 WM60 has been observed. It completes a rotation on its axis every 12.83 hours.
2001 WM60's orbit is 3.94 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.
2001 WM60's orbit is determined by observations dating back to March 9, 1994. It was last officially observed on Nov. 21, 2022. The IAU Minor Planet Center records 447 observations used to determine its orbit.
