Overview
2022 JO is a very small asteroid whose orbit crosses the orbit of Earth. NASA JPL has classified 2022 JO 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 JO orbits the sun every 546 days (1.49 years), coming as close as 0.93 AU and reaching as far as 1.68 AU from the sun. Based on its brightness and the way it reflects light, 2022 JO is probably between 0.012 to 0.054 kilometers in diameter, making it a small to average asteroid, very roughly comparable in size to a school bus or smaller.
Close Approaches
2022 JO's orbit is 0.02 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 JO has 8 close approaches predicted in the coming decades:
| Date | Distance from Earth (km) | Velocity (km/s) |
|---|---|---|
| May 19, 2019 | 5,521,608 | 6.908 |
| May 15, 2022 | 3,385,965 | 7.693 |
| May 9, 2025 | 8,350,892 | 9.044 |
| May 4, 2028 | 20,028,526 | 11.291 |
| Sept. 13, 2098 | 24,405,986 | 11.033 |
| Sept. 8, 2101 | 16,192,211 | 8.531 |
| May 18, 2119 | 4,264,404 | 7.260 |
| May 16, 2122 | 3,798,040 | 7.828 |
Images and Observations
2022 JO's orbit is determined by observations dating back to May 4, 2022. It was last officially observed on May 19, 2022. The IAU Minor Planet Center records 72 observations used to determine its orbit.
Accessibility and Exploration
2022 JO can be reached with a journey of 354 days. This trajectory would require a delta-v of 9.523 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 2,188 potential trajectories and launch windows to this asteroid.
