2011 UN411 is a large asteroid whose orbit extends beyond the orbit of Neptune. NASA JPL has not classified 2011 UN411 as potentially hazardous because its orbit does not bring it close to Earth.
2011 UN411 orbits the sun every 102,000 days (279.26 years), coming as close as 33.44 AU and reaching as far as 52.08 AU from the sun. Based on its brightness and the way it reflects light, 2011 UN411 is probably between 38.420 to 85.909 kilometers in diameter, making it larger than 99% of asteroids, very roughly comparable in size to the U.S. state of Rhode Island.
2011 UN411's orbit is 32.40 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 UN411's orbit is determined by observations dating back to Aug. 30, 2011. It was last officially observed on Feb. 6, 2013. The IAU Minor Planet Center records 23 observations used to determine its orbit.
