2022 WN2 is a very small asteroid whose orbit crosses the orbit of Earth. NASA JPL has classified 2022 WN2 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 WN2 orbits the sun every 375 days (1.03 years), coming as close as 0.95 AU and reaching as far as 1.08 AU from the sun. Based on its brightness and the way it reflects light, 2022 WN2 is probably between 0.003 to 0.013 kilometers in diameter, making it a small to average asteroid, very roughly comparable in size to a school bus or smaller.
2022 WN2's orbit is 0.01 AU from Earth's orbit at its closest point. This means that its orbit is relatively close to Earth's orbit.
2022 WN2 has 13 close approaches predicted in the coming decades:

2022 WN2's orbit is determined by observations dating back to Nov. 20, 2022. It was last officially observed on Nov. 25, 2022. The IAU Minor Planet Center records 30 observations used to determine its orbit.
2022 WN2 can be reached with a journey of 362 days. This trajectory would require a delta-v of 5.33 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 352,771 potential trajectories and launch windows to this asteroid.
