Overview
436671 (2011 SV71) is a mid-sized asteroid whose orbit approaches the orbit of Earth but does not cross it. NASA JPL has classified 2011 SV71 as a "Potentially Hazardous Asteroid" due to its predicted close pass(es) with Earth.
2011 SV71 orbits the sun every 1,560 days (4.27 years), coming as close as 1.02 AU and reaching as far as 4.23 AU from the sun. 2011 SV71 is about 2.2 kilometers in diameter, making it larger than 99% of asteroids, comparable in size to Mount Everest.
Close Approaches
2011 SV71's orbit is 0.01 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.
2011 SV71 has 2 close approaches predicted in the coming decades:
| Date | Distance from Earth (km) | Velocity (km/s) |
|---|---|---|
| June 26, 2045 | 12,829,238 | 10.778 |
| July 14, 2105 | 27,269,174 | 12.133 |
