Overview
2019 PG1 is a very small asteroid whose orbit crosses the orbit of Earth. NASA JPL has classified 2019 PG1 as a "Potentially Hazardous Asteroid" due to its predicted close pass(es) with Earth.
2019 PG1 orbits the sun every 1,410 days (3.86 years), coming as close as 1.00 AU and reaching as far as 3.92 AU from the sun. Based on its brightness and the way it reflects light, 2019 PG1 is probably between 0.200 to 0.447 kilometers in diameter, making it a small to average asteroid, very roughly comparable in size to a football field.
Close Approaches
2019 PG1's orbit is 0.01 AU from Earth's orbit at its closest point. This means that its orbit is relatively close to Earth's orbit.
2019 PG1 has 3 close approaches predicted in the coming decades:
| Date | Distance from Earth (km) | Velocity (km/s) |
|---|---|---|
| July 24, 2019 | 23,652,694 | 14.553 |
| June 29, 2065 | 5,716,233 | 15.132 |
| July 8, 2111 | 4,756,976 | 13.890 |
