Overview
2004 TG10 is a mid-sized asteroid whose orbit crosses the orbit of Earth. NASA JPL has classified 2004 TG10 as a "Potentially Hazardous Asteroid" due to its predicted close pass(es) with Earth.
2004 TG10 orbits the sun every 1,220 days (3.34 years), coming as close as 0.31 AU and reaching as far as 4.16 AU from the sun. Its orbit is highly elliptical. 2004 TG10 is about 1.3 kilometers in diameter, making it larger than 99% of asteroids, comparable in size to the U.S. Pentagon.
Close Approaches
2004 TG10'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 TG10 has 4 close approaches predicted in the coming decades:
| Date | Distance from Earth (km) | Velocity (km/s) |
|---|---|---|
| July 11, 2068 | 21,312,366 | 33.828 |
| Nov. 16, 2111 | 23,244,943 | 25.455 |
| Nov. 7, 2148 | 10,767,750 | 30.593 |
| Nov. 11, 2198 | 15,967,772 | 27.977 |
