51958 (2001 QJ256) is a large asteroid that shares Jupiter's orbit around the sun. NASA JPL has not classified 2001 QJ256 as potentially hazardous because its orbit does not bring it close to Earth.
2001 QJ256 orbits the sun every 4,210 days (11.53 years), coming as close as 4.54 AU and reaching as far as 5.66 AU from the sun. 2001 QJ256 is about 27.2 kilometers in diameter, making it larger than 99% of asteroids, comparable in size to the city of Indianapolis.
The rotation of 2001 QJ256 has been observed. It completes a rotation on its axis every 16.79 hours.
2001 QJ256's orbit is 3.59 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 QJ256's orbit is determined by observations dating back to Oct. 12, 1990. It was last officially observed on June 17, 2023. The IAU Minor Planet Center records 1,397 observations used to determine its orbit.
