2021 NS71 is a large asteroid whose orbit extends beyond the orbit of Neptune. NASA JPL has not classified 2021 NS71 as potentially hazardous because its orbit does not bring it close to Earth.
2021 NS71 orbits the sun every 83,400 days (228.34 years), coming as close as 3.53 AU and reaching as far as 71.19 AU from the sun. Its orbit is highly elliptical. Based on its brightness and the way it reflects light, 2021 NS71 is probably between 63.761 to 142.574 kilometers in diameter, making it larger than 99% of asteroids, very roughly comparable in size to the U.S. state of Delaware.
2021 NS71's orbit is 2.55 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.
2021 NS71's orbit is determined by observations dating back to July 5, 2021. It was last officially observed on Sept. 5, 2021. The IAU Minor Planet Center records 6 observations used to determine its orbit.
