Overview
2012 LK11 is a very small asteroid whose orbit crosses the orbit of Earth. NASA JPL has classified 2012 LK11 as a "Potentially Hazardous Asteroid" due to its predicted close pass(es) with Earth.
2012 LK11 orbits the sun every 1,380 days (3.78 years), coming as close as 0.99 AU and reaching as far as 3.87 AU from the sun. Based on its brightness and the way it reflects light, 2012 LK11 is probably between 0.234 to 0.522 kilometers in diameter, making it larger than 90% of asteroids but tiny compared to large asteroids, very roughly comparable in size to a football field.
Close Approaches
2012 LK11'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.
2012 LK11 has 6 close approaches predicted in the coming decades:
| Date | Distance from Earth (km) | Velocity (km/s) |
|---|---|---|
| July 5, 2061 | 10,913,016 | 10.496 |
| Sept. 19, 2095 | 29,067,122 | 14.874 |
| July 26, 2129 | 8,692,046 | 9.464 |
| Sept. 8, 2144 | 6,162,269 | 11.184 |
| June 25, 2163 | 25,297,546 | 13.626 |
| July 16, 2182 | 9,133,895 | 9.797 |
