Overview
466130 (2012 FZ23) is a small asteroid whose orbit crosses the orbit of Earth. NASA JPL has classified 2012 FZ23 as a "Potentially Hazardous Asteroid" due to its predicted close pass(es) with Earth.
2012 FZ23 orbits the sun every 1,430 days (3.92 years), coming as close as 0.97 AU and reaching as far as 4.00 AU from the sun. Based on its brightness and the way it reflects light, 2012 FZ23 is probably between 0.595 to 1.331 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.
Close Approaches
2012 FZ23'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.
2012 FZ23 has 3 close approaches predicted in the coming decades:
| Date | Distance from Earth (km) | Velocity (km/s) |
|---|---|---|
| March 17, 2055 | 13,250,580 | 42.934 |
| March 19, 2140 | 9,449,945 | 42.983 |
| March 23, 2179 | 2,792,729 | 41.974 |
