2022 TD is a very small asteroid whose orbit crosses the orbit of Earth. NASA JPL has classified 2022 TD 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.
2022 TD orbits the sun every 367 days (1.00 years), coming as close as 0.68 AU and reaching as far as 1.33 AU from the sun. Based on its brightness and the way it reflects light, 2022 TD is probably between 0.005 to 0.022 kilometers in diameter, making it a small to average asteroid, very roughly comparable in size to a school bus or smaller.
2022 TD'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.
2022 TD has 31 close approaches predicted in the coming decades:

2022 TD's orbit is determined by observations dating back to Oct. 1, 2022. It was last officially observed on Oct. 6, 2022. The IAU Minor Planet Center records 76 observations used to determine its orbit.
2022 TD can be reached with a journey of 418 days. This trajectory would require a delta-v of 10.464 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 2,875 potential trajectories and launch windows to this asteroid.
