Overview

2022 UO is a very small asteroid whose orbit crosses the orbit of Earth. NASA JPL has classified 2022 UO 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 UO orbits the sun every 375 days (1.03 years), coming as close as 0.91 AU and reaching as far as 1.13 AU from the sun. Based on its brightness and the way it reflects light, 2022 UO is probably between 0.013 to 0.029 kilometers in diameter, making it a small to average asteroid, very roughly comparable in size to a school bus or smaller.

Close Approaches

2022 UO's orbit is 0.03 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 UO has 5 close approaches predicted in the coming decades:

Date Distance from Earth (km) Velocity (km/s)
Oct. 14, 2021 23,726,124 16.871
Oct. 17, 2022 6,410,374 15.501
Oct. 19, 2023 23,846,214 15.341
April 8, 2024 18,021,983 15.747
April 15, 2025 7,583,589 16.190
