Overview
2022 PX1 is a very small asteroid whose orbit crosses the orbit of Earth. NASA JPL has classified 2022 PX1 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 PX1 orbits the sun every 957 days (2.62 years), coming as close as 0.22 AU and reaching as far as 3.58 AU from the sun. Its orbit is highly elliptical. Based on its brightness and the way it reflects light, 2022 PX1 is probably between 0.097 to 0.217 kilometers in diameter, making it a small to average asteroid, very roughly comparable in size to a school bus or smaller.
Close Approaches
2022 PX1'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 PX1 has 1 close approaches predicted in the coming decades:
| Date | Distance from Earth (km) | Velocity (km/s) |
|---|---|---|
| Aug. 12, 2022 | 1,087,591 | 35.121 |
NASA Sentry has assessed impact risk for 1 very close approach scenarios. Here are the top scenarios ordered by probability of impact:
| Date | Probability of Impact (%) | Impact Energy (Mt) |
|---|---|---|
| Aug. 11, 2040 | 0.00032 | 361.7 |
