Overview
2017 VX1 is a very small asteroid whose orbit crosses the orbit of Earth. NASA JPL has classified 2017 VX1 as a "Potentially Hazardous Asteroid" due to its predicted close pass(es) with Earth.
2017 VX1 orbits the sun every 992 days (2.72 years), coming as close as 0.92 AU and reaching as far as 2.97 AU from the sun. Based on its brightness and the way it reflects light, 2017 VX1 is probably between 0.254 to 0.568 kilometers in diameter, making it larger than 90% of asteroids but tiny compared to large asteroids, very roughly comparable in size to a football field.
Close Approaches
2017 VX1's orbit is 0.03 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.
2017 VX1 has 6 close approaches predicted in the coming decades:
| Date | Distance from Earth (km) | Velocity (km/s) |
|---|---|---|
| March 9, 2037 | 17,883,191 | 10.340 |
| March 20, 2056 | 22,331,429 | 11.863 |
| Dec. 28, 2104 | 13,646,693 | 12.603 |
| Dec. 29, 2123 | 13,883,161 | 12.602 |
| Dec. 22, 2142 | 24,416,375 | 14.782 |
| March 30, 2189 | 27,414,232 | 13.234 |
