139775 (2001 QG298) is a large asteroid whose orbit extends beyond the orbit of Neptune. NASA JPL has not classified 2001 QG298 as potentially hazardous because its orbit does not bring it close to Earth.
2001 QG298 orbits the sun every 90,900 days (248.87 years), coming as close as 31.74 AU and reaching as far as 47.38 AU from the sun. Based on its brightness and the way it reflects light, 2001 QG298 is probably between 116.026 to 259.442 kilometers in diameter, making it larger than 99% of asteroids, very roughly comparable in size to the U.S. state of New Jersey.
The rotation of 2001 QG298 has been observed. It completes a rotation on its axis every 13.77 hours.
2001 QG298's orbit is 30.70 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.
2001 QG298's orbit is determined by observations dating back to Aug. 19, 2001. It was last officially observed on Oct. 20, 2020. The IAU Minor Planet Center records 357 observations used to determine its orbit.
