Overview
68267 (2001 EA16) is a small asteroid whose orbit crosses the orbit of Earth. NASA JPL has classified 2001 EA16 as a "Near Earth Asteroid" due to its orbit's proximity to Earth, but it is not considered potentially hazardous because computer simulations have not indicated any imminent likelihood of future collision.
2001 EA16 orbits the sun every 678 days (1.86 years), coming as close as 0.86 AU and reaching as far as 2.16 AU from the sun. 2001 EA16 is about 0.9 kilometers in diameter, making it larger than ~97% of asteroids but small compared to large asteroids, comparable in size to the Golden Gate Bridge.
The rotation of 2001 EA16 has been observed. It completes a rotation on its axis every 3.50 hours.
Close Approaches
2001 EA16's orbit is 0.06 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.
2001 EA16 has 6 close approaches predicted in the coming decades:
| Date | Distance from Earth (km) | Velocity (km/s) |
