Overview
2015 FS332 is a small asteroid whose orbit crosses the orbit of Earth. NASA JPL has classified 2015 FS332 as a "Potentially Hazardous Asteroid" due to its predicted close pass(es) with Earth.
2015 FS332 orbits the sun every 887 days (2.43 years), coming as close as 0.95 AU and reaching as far as 2.66 AU from the sun. Based on its brightness and the way it reflects light, 2015 FS332 is probably between 0.545 to 1.219 kilometers in diameter, making it larger than ~97% of asteroids but small compared to large asteroids, very roughly comparable in size to the Golden Gate Bridge.
The rotation of 2015 FS332 has been observed. It completes a rotation on its axis every 2.41 hours.
Close Approaches
2015 FS332's orbit is 0.04 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.
2015 FS332 has 6 close approaches predicted in the coming decades:
| Date | Distance from Earth (km) | Velocity (km/s) |
