Overview
395207 (2010 HQ80) is a small asteroid whose orbit crosses the orbit of Earth. NASA JPL has classified 2010 HQ80 as a "Potentially Hazardous Asteroid" due to its predicted close pass(es) with Earth.
2010 HQ80 orbits the sun every 717 days (1.96 years), coming as close as 0.80 AU and reaching as far as 2.34 AU from the sun. 2010 HQ80 is about 0.7 kilometers in diameter, making it larger than ~97% of asteroids but small compared to large asteroids, comparable in size to the Golden Gate Bridge.
Close Approaches
2010 HQ80'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 HQ80 has 5 close approaches predicted in the coming decades:
| Date | Distance from Earth (km) | Velocity (km/s) |
|---|---|---|
| April 21, 2020 | 17,437,174 | 22.210 |
| April 28, 2073 | 1,243,267 | 19.939 |
