Overview
2010 WZ8 is a very small asteroid whose orbit crosses the orbit of Earth. NASA JPL has classified 2010 WZ8 as a "Potentially Hazardous Asteroid" due to its predicted close pass(es) with Earth.
2010 WZ8 orbits the sun every 1,010 days (2.77 years), coming as close as 0.98 AU and reaching as far as 2.96 AU from the sun. Based on its brightness and the way it reflects light, 2010 WZ8 is probably between 0.186 to 0.415 kilometers in diameter, making it a small to average asteroid, very roughly comparable in size to a football field.
Close Approaches
2010 WZ8'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.
2010 WZ8 has 6 close approaches predicted in the coming decades:
| Date | Distance from Earth (km) | Velocity (km/s) |
|---|---|---|
| Jan. 13, 2047 | 1,603,924 | 7.199 |
| Jan. 1, 2072 | 5,154,995 | 8.268 |
| Dec. 14, 2107 | 29,880,946 | 13.544 |
| Feb. 24, 2119 | 9,952,462 | 8.518 |
| March 11, 2155 | 23,895,382 | 11.915 |
| Dec. 24, 2179 | 15,313,495 | 10.400 |
