2005 TN53 is a large asteroid whose orbit extends beyond the orbit of Neptune. NASA JPL has not classified 2005 TN53 as potentially hazardous because its orbit does not bring it close to Earth.
2005 TN53 orbits the sun every 61,000 days (167.01 years), coming as close as 28.21 AU and reaching as far as 32.45 AU from the sun. Based on its brightness and the way it reflects light, 2005 TN53 is probably between 42.126 to 94.198 kilometers in diameter, making it larger than 99% of asteroids, very roughly comparable in size to the U.S. state of Rhode Island.
2005 TN53's orbit is 27.30 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.
2005 TN53's orbit is determined by observations dating back to Oct. 7, 2005. It was last officially observed on Oct. 6, 2013. The IAU Minor Planet Center records 26 observations used to determine its orbit.
