2020 TH6 is a very small asteroid whose orbit crosses the orbit of Earth. NASA JPL has classified 2020 TH6 as a "Near Earth Asteroid" due to its orbit's proximity to Earth, but it is not considered potentially hazardous because computer simulations have not indicated any imminent likelihood of future collision.
2020 TH6 orbits the sun every 368 days (1.01 years), coming as close as 0.79 AU and reaching as far as 1.22 AU from the sun. Based on its brightness and the way it reflects light, 2020 TH6 is probably between 0.003 to 0.014 kilometers in diameter, making it a small to average asteroid, very roughly comparable in size to a school bus or smaller.
2020 TH6's orbit is 0.00 AU from Earth's orbit at its closest point. This means that its orbit is relatively close to Earth's orbit.
2020 TH6 has 33 close approaches predicted in the coming decades:

2020 TH6's orbit is determined by observations dating back to Oct. 15, 2020. It was last officially observed on Oct. 17, 2020. The IAU Minor Planet Center records 18 observations used to determine its orbit.
2020 TH6 can be reached with a journey of 386 days. This trajectory would require a delta-v of 6.092 km/s. To put this into perspective, the delta-v to launch a rocket to Low-Earth Orbit is 9.7 km/s. There are 1,268,386 potential trajectories and launch windows to this asteroid.
