20108 (1995 QZ9) is a large asteroid whose orbit extends beyond the orbit of Neptune. NASA JPL has not classified 1995 QZ9 as potentially hazardous because its orbit does not bring it close to Earth.
1995 QZ9 orbits the sun every 90,800 days (248.60 years), coming as close as 33.63 AU and reaching as far as 45.45 AU from the sun. Based on its brightness and the way it reflects light, 1995 QZ9 is probably between 76.658 to 171.412 kilometers in diameter, making it larger than 99% of asteroids, very roughly comparable in size to the U.S. state of Delaware.
1995 QZ9's orbit is 32.60 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.
1995 QZ9's orbit is determined by observations dating back to Aug. 29, 1995. It was last officially observed on Sept. 30, 2014. The IAU Minor Planet Center records 34 observations used to determine its orbit.
