Overview
496005 (2007 XJ16) is a small asteroid whose orbit crosses the orbit of Earth. NASA JPL has classified 2007 XJ16 as a "Potentially Hazardous Asteroid" due to its predicted close pass(es) with Earth.
2007 XJ16 orbits the sun every 1,240 days (3.39 years), coming as close as 1.00 AU and reaching as far as 3.51 AU from the sun. Based on its brightness and the way it reflects light, 2007 XJ16 is probably between 0.402 to 0.900 kilometers in diameter, making it larger than ~97% of asteroids but small compared to large asteroids, very roughly comparable in size to the Golden Gate Bridge.
Close Approaches
2007 XJ16's orbit is 0.03 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.
2007 XJ16 has 5 close approaches predicted in the coming decades:
| Date | Distance from Earth (km) | Velocity (km/s) |
|---|---|---|
| Aug. 3, 2034 | 7,492,990 | 10.175 |
| Aug. 11, 2078 | 4,395,617 | 9.120 |
| Sept. 30, 2105 | 15,482,149 | 9.486 |
| July 28, 2149 | 16,526,665 | 12.020 |
| July 31, 2176 | 12,656,539 | 11.342 |
