15820 (1994 TB) is a average-sized 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 89,800 days (245.86 years), coming as close as 26.97 AU and reaching as far as 51.51 AU from the sun. Based on its brightness and the way it reflects light, 1994 TB is probably between 92.163 to 206.082 kilometers in diameter, making it larger than most asteroids, very roughly comparable in size to the U.S. state of Connecticut.
The rotation of 1994 TB has been observed. It completes a rotation on its axis every 6.50 days.
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 Sept. 14, 2018. The IAU Minor Planet Center records 99 observations used to determine its orbit.
