Overview
2022 UC22 is a very small asteroid whose orbit approaches the orbit of Earth but does not cross it. NASA JPL has classified 2022 UC22 as a "Potentially Hazardous Asteroid" due to its predicted close pass(es) with Earth.
2022 UC22 orbits the sun every 949 days (2.60 years), coming as close as 1.02 AU and reaching as far as 2.76 AU from the sun. Based on its brightness and the way it reflects light, 2022 UC22 is probably between 0.154 to 0.345 kilometers in diameter, making it a small to average asteroid, very roughly comparable in size to a football field.
Close Approaches
2022 UC22'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 UC22 has 6 close approaches predicted in the coming decades:
| Date | Distance from Earth (km) | Velocity (km/s) |
|---|---|---|
| Nov. 7, 2022 | 7,002,011 | 17.368 |
| Nov. 3, 2035 | 16,799,871 | 17.646 |
| Nov. 19, 2131 | 23,082,588 | 17.888 |
| Nov. 13, 2144 | 9,142,728 | 17.380 |
| Nov. 12, 2157 | 6,720,592 | 17.340 |
| Nov. 16, 2170 | 16,148,572 | 17.557 |
