2007 EK is a very small asteroid whose orbit crosses the orbit of Earth. NASA JPL has classified 2007 EK 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.
2007 EK orbits the sun every 437 days (1.20 years), coming as close as 0.82 AU and reaching as far as 1.43 AU from the sun. Based on its brightness and the way it reflects light, 2007 EK is probably between 0.002 to 0.011 kilometers in diameter, making it a small to average asteroid, very roughly comparable in size to a school bus or smaller.
2007 EK's orbit is 0.00 AU from Earth's orbit at its closest point. This means that its orbit is relatively close to Earth's orbit.
2007 EK has 3 close approaches predicted in the coming decades:
| Date | Distance from Earth (km) | Velocity (km/s) |
|---|---|---|
| Sept. 6, 2020 | 26,023,316 | 13.445 |
| Aug. 30, 2026 | 4,188,766 | 9.141 |
| Aug. 26, 2032 | 3,700,531 | 7.618 |
NASA Sentry has assessed impact risk for 1 very close approach scenarios. Here are the top scenarios ordered by probability of impact:
| Date | Probability of Impact (%) | Impact Energy (Mt) |
|---|---|---|
| Sept. 7, 2093 | 0.00000 | 0.003347 |
2007 EK's orbit is determined by observations dating back to March 9, 2007. It was last officially observed on March 13, 2007. The IAU Minor Planet Center records 38 observations used to determine its orbit.
2007 EK can be reached with a journey of 378 days. This trajectory would require a delta-v of 8.03 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 40,698 potential trajectories and launch windows to this asteroid.
