2022 WN1 is a very small asteroid whose orbit crosses the orbit of Earth. NASA JPL has classified 2022 WN1 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 WN1 orbits the sun every 724 days (1.98 years), coming as close as 1.01 AU and reaching as far as 2.15 AU from the sun. Based on its brightness and the way it reflects light, 2022 WN1 is probably between 0.019 to 0.041 kilometers in diameter, making it a small to average asteroid, very roughly comparable in size to a school bus or smaller.
2022 WN1's orbit is 0.05 AU from Earth's orbit at its closest point. This means that there is a wide berth between this asteroid and Earth at all times.
2022 WN1 has 3 close approaches predicted in the coming decades:
| Date | Distance from Earth (km) | Velocity (km/s) |
|---|---|---|
| Dec. 3, 2020 | 21,695,975 | 9.645 |
| Nov. 22, 2022 | 7,080,530 | 10.034 |
| Nov. 13, 2024 | 18,589,089 | 11.848 |
2022 WN1's orbit is determined by observations dating back to Nov. 18, 2022. It was last officially observed on Nov. 28, 2022. The IAU Minor Planet Center records 57 observations used to determine its orbit.
