Overview
164216 (2004 OT11) is a mid-sized asteroid whose orbit crosses the orbit of Earth. NASA JPL has classified 2004 OT11 as a "Potentially Hazardous Asteroid" due to its predicted close pass(es) with Earth.
2004 OT11 orbits the sun every 1,150 days (3.15 years), coming as close as 0.94 AU and reaching as far as 3.37 AU from the sun. Based on its brightness and the way it reflects light, 2004 OT11 is probably between 0.934 to 2.089 kilometers in diameter, making it larger than 99% of asteroids, very roughly comparable in size to the U.S. Pentagon.
Close Approaches
2004 OT11's orbit is 0.02 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.
2004 OT11 has 5 close approaches predicted in the coming decades:
| Date | Distance from Earth (km) | Velocity (km/s) |
|---|---|---|
| July 26, 2026 | 12,292,363 | 16.883 |
| June 23, 2045 | 27,614,746 | 13.872 |
| Aug. 2, 2086 | 25,785,898 | 18.604 |
| July 16, 2105 | 4,050,265 | 14.974 |
| July 4, 2146 | 18,357,775 | 14.076 |
