20161 (1996 TR66) is a large asteroid whose orbit extends beyond the orbit of Neptune. NASA JPL has not classified 1996 TR66 as potentially hazardous because its orbit does not bring it close to Earth.
1996 TR66 orbits the sun every 122,000 days (334.02 years), coming as close as 28.94 AU and reaching as far as 67.50 AU from the sun. Based on its brightness and the way it reflects light, 1996 TR66 is probably between 86.807 to 194.106 kilometers in diameter, making it larger than 99% of asteroids, very roughly comparable in size to the U.S. state of Delaware.
1996 TR66's orbit is 27.90 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.
1996 TR66's orbit is determined by observations dating back to Oct. 8, 1996. It was last officially observed on Aug. 12, 2016. The IAU Minor Planet Center records 32 observations used to determine its orbit.
