Overview
2022 OH is a very small asteroid whose orbit crosses the orbit of Earth. NASA JPL has classified 2022 OH as a "Potentially Hazardous Asteroid" due to its predicted close pass(es) with Earth.
2022 OH orbits the sun every 1,500 days (4.11 years), coming as close as 0.95 AU and reaching as far as 4.18 AU from the sun. Based on its brightness and the way it reflects light, 2022 OH is probably between 0.191 to 0.427 kilometers in diameter, making it a small to average asteroid, very roughly comparable in size to a football field.
Close Approaches
2022 OH's orbit is 0.00 AU from Earth's orbit at its closest point. This means that its orbit is relatively close to Earth's orbit.
2022 OH has 6 close approaches predicted in the coming decades:
| Date | Distance from Earth (km) | Velocity (km/s) |
|---|---|---|
| Aug. 29, 2022 | 22,768,660 | 14.900 |
| Nov. 29, 2067 | 15,344,661 | 12.832 |
| Sept. 7, 2096 | 18,132,955 | 12.996 |
| Sept. 1, 2129 | 20,992,128 | 14.795 |
| Dec. 11, 2133 | 29,178,055 | 16.406 |
| Nov. 20, 2174 | 4,443,285 | 10.202 |
