Asteroid 2012 DA14 – Earth Flyby to Safely Pass Earth
Asteroid 2012 DA14 is a small near-Earth object – approximately 150 feet (45 meters) in diameter. On Feb. 15, 2013, the asteroid will pass by our planet at a remarkably close distance, but the asteroid’s path is understood well enough that there is no chance of a collision with the Earth. The flyby will be the closest known approach to Earth for an object its size.
DA14 will be only about 17,200 miles (27,700 kilometers) above Earth’s surface at the time of closest approach on Feb 15, 2013. This distance is well outside Earth’s atmosphere, but it is inside the belt of satellites in geostationary orbit, which is located 22,200 miles (35,800 kilometers) above Earth’s surface. The close-approach distance is only about one-tenth the distance between Earth and moon.
