An asteroid the size of a tour bus has zipped harmlessly past Earth, giving skywatchers and astronomers a great target for fascinating video and photos.
Asteroid 2011 MD, reached its closest point to Earth on Monday 1700 GMT, when it crept within 7,500 miles (12, 000 kilometers) of Earth before whipping away again like a slingshot.
The asteroid was flying over the southern Atlantic Ocean, off the coast of Antarctica, at the time of its closest approach.
It was discovered just last week, but there was never any risk of it impacting Earth, NASA scientists said. Asteroids this size can be expected to buzz Earth with close shaves about once every six years.
