2013 TK172 is a large asteroid whose orbit extends beyond the orbit of Neptune. NASA JPL has not classified 2013 TK172 as potentially hazardous because its orbit does not bring it close to Earth.
2013 TK172 orbits the sun every 117,000 days (320.33 years), coming as close as 36.99 AU and reaching as far as 56.55 AU from the sun. Based on its brightness and the way it reflects light, 2013 TK172 is probably between 110.804 to 247.765 kilometers in diameter, making it larger than 99% of asteroids, very roughly comparable in size to the U.S. state of Connecticut.
2013 TK172's orbit is 36.00 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 TK172's orbit is determined by observations dating back to Oct. 4, 2013. It was last officially observed on Nov. 4, 2016. The IAU Minor Planet Center records 18 observations used to determine its orbit.
