Teharonhiawako is a very large asteroid whose orbit extends beyond the orbit of Neptune. NASA JPL has not classified Teharonhiawako as potentially hazardous because its orbit does not bring it close to Earth.
Teharonhiawako orbits the sun every 108,000 days (295.69 years), coming as close as 43.41 AU and reaching as far as 45.23 AU from the sun. Based on its brightness and the way it reflects light, Teharonhiawako is probably between 169.260 to 378.477 kilometers in diameter, making it larger than 99% of asteroids, very roughly comparable in size to the U.S. state of Maryland.
Teharonhiawako's orbit is 42.40 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.
Teharonhiawako's orbit is determined by observations dating back to Aug. 1, 2000. It was last officially observed on Sept. 21, 2020. The IAU Minor Planet Center records 195 observations used to determine its orbit.
