Overview
2019 AV is a very small asteroid whose orbit crosses the orbit of Earth. NASA JPL has classified 2019 AV 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.
2019 AV orbits the sun every 543 days (1.49 years), coming as close as 0.83 AU and reaching as far as 1.77 AU from the sun. Based on its brightness and the way it reflects light, 2019 AV is probably between 0.024 to 0.107 kilometers in diameter, making it a small to average asteroid, very roughly comparable in size to a school bus or smaller.
Close Approaches
2019 AV'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 AV has 4 close approaches predicted in the coming decades:
| Date | Distance from Earth (km) | Velocity (km/s) |
|---|---|---|
| Feb. 18, 2019 | 11,925,209 | 7.718 |
| Feb. 1, 2022 | 12,806,776 | 12.471 |
| Feb. 13, 2071 | 6,568,738 | 8.666 |
| Jan. 31, 2074 | 16,218,754 | 13.146 |
Images and Observations
2019 AV's orbit is determined by observations dating back to Jan. 2, 2019. It was last officially observed on Feb. 11, 2019. The IAU Minor Planet Center records 20 observations used to determine its orbit.
Accessibility and Exploration
2019 AV can be reached with a journey of 378 days. This trajectory would require a delta-v of 11.565 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 50 potential trajectories and launch windows to this asteroid.
