149560 (2003 QZ91) is a large asteroid whose orbit extends beyond the orbit of Neptune. NASA JPL has not classified 2003 QZ91 as potentially hazardous because its orbit does not bring it close to Earth.
2003 QZ91 orbits the sun every 98,700 days (270.23 years), coming as close as 21.88 AU and reaching as far as 61.74 AU from the sun. Based on its brightness and the way it reflects light, 2003 QZ91 is probably between 76.305 to 170.624 kilometers in diameter, making it larger than 99% of asteroids, very roughly comparable in size to the U.S. state of Delaware.
2003 QZ91's orbit is 20.90 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.
2003 QZ91's orbit is determined by observations dating back to Aug. 24, 2003. It was last officially observed on Sept. 4, 2015. The IAU Minor Planet Center records 21 observations used to determine its orbit.
