15820 (1994 TB) is a large asteroid whose orbit extends beyond the orbit of Neptune. NASA JPL has not classified 1994 TB as potentially hazardous because its orbit does not bring it close to Earth.
1994 TB orbits the sun every 91,900 days (251.61 years), coming as close as 26.96 AU and reaching as far as 52.72 AU from the sun. Based on its brightness and the way it reflects light, 1994 TB is probably between 80.641 to 180.318 kilometers in diameter, making it larger than 99% of asteroids, very roughly comparable in size to the U.S. state of Delaware.
The rotation of 1994 TB has been observed. It completes a rotation on its axis every 6.00 hours.
1994 TB's orbit is 26.00 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.
1994 TB's orbit is determined by observations dating back to Oct. 13, 1994. It was last officially observed on Jan. 11, 2021. The IAU Minor Planet Center records 165 observations used to determine its orbit.
