Overview
2022 BJ is a very small asteroid whose orbit crosses the orbit of Earth. NASA JPL has classified 2022 BJ as a "Potentially Hazardous Asteroid" due to its predicted close pass(es) with Earth.
2022 BJ orbits the sun every 1,350 days (3.70 years), coming as close as 0.48 AU and reaching as far as 4.31 AU from the sun. Its orbit is highly elliptical. Based on its brightness and the way it reflects light, 2022 BJ is probably between 0.136 to 0.303 kilometers in diameter, making it a small to average asteroid, very roughly comparable in size to a football field.
Close Approaches
2022 BJ'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 BJ has 4 close approaches predicted in the coming decades:
| Date | Distance from Earth (km) | Velocity (km/s) |
|---|---|---|
| Jan. 18, 2022 | 7,891,907 | 24.402 |
| July 5, 2025 | 8,026,126 | 23.996 |
| June 26, 2051 | 18,519,857 | 29.036 |
| Jan. 26, 2100 | 16,964,333 | 28.597 |
