Overview
612337 (2002 EY2) is a very small asteroid whose orbit crosses the orbit of Earth. NASA JPL has classified 2002 EY2 as a "Potentially Hazardous Asteroid" due to its predicted close pass(es) with Earth.
2002 EY2 orbits the sun every 828 days (2.27 years), coming as close as 0.89 AU and reaching as far as 2.56 AU from the sun. Based on its brightness and the way it reflects light, 2002 EY2 is probably between 0.342 to 0.766 kilometers in diameter, making it larger than 90% of asteroids but tiny compared to large asteroids, very roughly comparable in size to the U.S. Capitol building.
Close Approaches
2002 EY2's orbit is 0.00 AU from Earth's orbit at its closest point. This means that its orbit is very close to Earth's orbit.
2002 EY2 has 6 close approaches predicted in the coming decades:
| Date | Distance from Earth (km) | Velocity (km/s) |
|---|---|---|
| Aug. 29, 2044 | 16,968,786 | 18.008 |
| Aug. 24, 2078 | 28,953,605 | 19.810 |
