Overview
435159 (2007 LQ19) is a mid-sized asteroid whose orbit crosses the orbit of Earth. NASA JPL has classified 2007 LQ19 as a "Potentially Hazardous Asteroid" due to its predicted close pass(es) with Earth.
2007 LQ19 orbits the sun every 1,540 days (4.22 years), coming as close as 0.96 AU and reaching as far as 4.25 AU from the sun. Based on its brightness and the way it reflects light, 2007 LQ19 is probably between 0.992 to 2.218 kilometers in diameter, making it larger than 99% of asteroids, very roughly comparable in size to the U.S. Pentagon.
Close Approaches
2007 LQ19'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.
2007 LQ19 has 1 close approaches predicted in the coming decades:
| Date | Distance from Earth (km) | Velocity (km/s) |
|---|---|---|
| July 2, 2154 | 11,433,818 | 15.833 |
