470596 (2008 NW4) is a very large asteroid whose orbit extends beyond the orbit of Neptune. NASA JPL has not classified 2008 NW4 as potentially hazardous because its orbit does not bring it close to Earth.
2008 NW4 orbits the sun every 112,000 days (306.64 years), coming as close as 36.56 AU and reaching as far as 54.36 AU from the sun. Based on its brightness and the way it reflects light, 2008 NW4 is probably between 191.670 to 428.588 kilometers in diameter, making it larger than 99% of asteroids, very roughly comparable in size to the U.S. state of Maryland.
2008 NW4's orbit is 35.60 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.
2008 NW4's orbit is determined by observations dating back to July 7, 2008. It was last officially observed on June 19, 2023. The IAU Minor Planet Center records 312 observations used to determine its orbit.
