2010 WG9 is a large asteroid whose orbit extends beyond the orbit of Neptune. NASA JPL has not classified 2010 WG9 as potentially hazardous because its orbit does not bring it close to Earth.
2010 WG9 orbits the sun every 143,000 days (391.51 years), coming as close as 18.74 AU and reaching as far as 88.48 AU from the sun. 2010 WG9 is about 112.7 kilometers in diameter, making it larger than 99% of asteroids, comparable in size to the U.S. state of Delaware.
The rotation of 2010 WG9 has been observed. It completes a rotation on its axis every 263.80 hours.
2010 WG9's orbit is 18.20 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.
2010 WG9's orbit is determined by observations dating back to Dec. 24, 2009. It was last officially observed on March 13, 2017. The IAU Minor Planet Center records 123 observations used to determine its orbit.
