2013 SM100 is a large asteroid whose orbit extends beyond the orbit of Neptune. NASA JPL has not classified 2013 SM100 as potentially hazardous because its orbit does not bring it close to Earth.
2013 SM100 orbits the sun every 113,000 days (309.38 years), coming as close as 39.64 AU and reaching as far as 51.72 AU from the sun. Based on its brightness and the way it reflects light, 2013 SM100 is probably between 53.034 to 118.588 kilometers in diameter, making it larger than 99% of asteroids, very roughly comparable in size to the U.S. state of Rhode Island.
2013 SM100's orbit is 38.60 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.
2013 SM100's orbit is determined by observations dating back to Aug. 5, 2013. It was last officially observed on Aug. 30, 2017. The IAU Minor Planet Center records 43 observations used to determine its orbit.
