2011 QF99 is a large asteroid with an orbit between Jupiter and Neptune. NASA JPL has not classified 2011 QF99 as potentially hazardous because its orbit does not bring it close to Earth.
2011 QF99 orbits the sun every 30,700 days (84.05 years), coming as close as 15.77 AU and reaching as far as 22.57 AU from the sun. Based on its brightness and the way it reflects light, 2011 QF99 is probably between 29.144 to 65.169 kilometers in diameter, making it larger than 99% of asteroids, very roughly comparable in size to the city of Houston.
2011 QF99's orbit is 14.80 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.
2011 QF99's orbit is determined by observations dating back to Nov. 2, 2008. It was last officially observed on Dec. 18, 2018. The IAU Minor Planet Center records 91 observations used to determine its orbit.
