2011 ED12 is a very small asteroid whose orbit crosses the orbit of Earth. NASA JPL has classified 2011 ED12 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.
2011 ED12 orbits the sun every 420 days (1.15 years), coming as close as 0.95 AU and reaching as far as 1.25 AU from the sun. Based on its brightness and the way it reflects light, 2011 ED12 is probably between 0.008 to 0.034 kilometers in diameter, making it a small to average asteroid, very roughly comparable in size to a school bus or smaller.
2011 ED12's orbit is 0.01 AU from Earth's orbit at its closest point. This means that its orbit is relatively close to Earth's orbit.
2011 ED12 has 4 close approaches predicted in the coming decades:
| Date | Distance from Earth (km) | Velocity (km/s) |
|---|---|---|
| Nov. 6, 2025 | 17,899,340 | 6.268 |
| May 17, 2026 | 28,258,054 | 3.432 |
| Sept. 16, 2033 | 23,684,549 | 3.186 |
| March 7, 2034 | 7,728,487 | 4.593 |
2011 ED12's orbit is determined by observations dating back to March 5, 2011. It was last officially observed on March 25, 2011. The IAU Minor Planet Center records 86 observations used to determine its orbit.
2011 ED12 can be reached with a journey of 370 days. This trajectory would require a delta-v of 5.842 km/s. To put this into perspective, the delta-v to launch a rocket to Low-Earth Orbit is 9.7 km/s. There are 422,394 potential trajectories and launch windows to this asteroid.
