2022 UJ1 is a very small asteroid whose orbit could bring it in close proximity to Earth. NASA JPL has classified 2022 UJ1 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 UJ1 orbits the sun every 339 days (0.93 years), coming as close as 0.89 AU and reaching as far as 1.02 AU from the sun. Based on its brightness and the way it reflects light, 2022 UJ1 is probably between 0.005 to 0.020 kilometers in diameter, making it a small to average asteroid, very roughly comparable in size to a school bus or smaller.
2022 UJ1's orbit is 0.01 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 UJ1 has 6 close approaches predicted in the coming decades:
|Date||Distance from Earth (km)||Velocity (km/s)|
|Oct. 18, 2022||2,746,011||4.499|
|March 18, 2023||16,624,918||5.136|
|Oct. 18, 2035||2,888,638||4.483|
|March 13, 2036||17,510,779||5.107|
|Oct. 8, 2047||25,328,956||7.740|
|Oct. 14, 2072||2,447,282||4.649|
2022 UJ1's orbit is determined by observations dating back to Oct. 17, 2022. It was last officially observed on Oct. 25, 2022. The IAU Minor Planet Center records 16 observations used to determine its orbit.
2022 UJ1 can be reached with a journey of 178 days. This trajectory would require a delta-v of 5.769 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 270,397 potential trajectories and launch windows to this asteroid.
