385533 (2004 QD29) is a large asteroid whose orbit extends beyond the orbit of Neptune. NASA JPL has not classified 2004 QD29 as potentially hazardous because its orbit does not bring it close to Earth.
2004 QD29 orbits the sun every 104,000 days (284.74 years), coming as close as 38.42 AU and reaching as far as 48.16 AU from the sun. Based on its brightness and the way it reflects light, 2004 QD29 is probably between 108.781 to 243.243 kilometers in diameter, making it larger than 99% of asteroids, very roughly comparable in size to the U.S. state of Connecticut.
2004 QD29's orbit is 37.50 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.
2004 QD29's orbit is determined by observations dating back to Aug. 19, 2004. It was last officially observed on Oct. 6, 2013. The IAU Minor Planet Center records 26 observations used to determine its orbit.
