2003 SN317 is a large asteroid whose orbit extends beyond the orbit of Neptune. NASA JPL has not classified 2003 SN317 as potentially hazardous because its orbit does not bring it close to Earth.
2003 SN317 orbits the sun every 101,000 days (276.52 years), coming as close as 40.62 AU and reaching as far as 44.52 AU from the sun. Based on its brightness and the way it reflects light, 2003 SN317 is probably between 133.216 to 297.879 kilometers in diameter, making it larger than 99% of asteroids, very roughly comparable in size to the U.S. state of Massachusetts.
2003 SN317's orbit is 39.60 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.
2003 SN317's orbit is determined by observations dating back to Oct. 2, 2000. It was last officially observed on Nov. 30, 2008. The IAU Minor Planet Center records 36 observations used to determine its orbit.
