15874 (1996 TL66) is a very large asteroid whose orbit extends beyond the orbit of Neptune. NASA JPL has not classified 1996 TL66 as potentially hazardous because its orbit does not bring it close to Earth.
1996 TL66 orbits the sun every 280,000 days (766.60 years), coming as close as 34.97 AU and reaching as far as 132.49 AU from the sun. Based on its brightness and the way it reflects light, 1996 TL66 is probably between 215.058 to 480.884 kilometers in diameter, making it larger than 99% of asteroids, very roughly comparable in size to the U.S. state of West Virginia.
The rotation of 1996 TL66 has been observed. It completes a rotation on its axis every 12.00 hours.
1996 TL66's orbit is 34.00 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.
1996 TL66's orbit is determined by observations dating back to Oct. 9, 1996. It was last officially observed on Jan. 8, 2022. The IAU Minor Planet Center records 501 observations used to determine its orbit.
