309139 (2006 XQ51) is a large asteroid with an orbit between Jupiter and Neptune. NASA JPL has not classified 2006 XQ51 as potentially hazardous because its orbit does not bring it close to Earth.
2006 XQ51 orbits the sun every 23,000 days (62.97 years), coming as close as 9.82 AU and reaching as far as 21.80 AU from the sun. 2006 XQ51 is about 39.1 kilometers in diameter, making it larger than 99% of asteroids, comparable in size to the city of Houston.
2006 XQ51's orbit is 8.90 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.
2006 XQ51's orbit is determined by observations dating back to Aug. 5, 2001. It was last officially observed on March 10, 2011. The IAU Minor Planet Center records 71 observations used to determine its orbit.
