An asteroid measuring 150ft (50m) across will whizz past Earth just 28,000km (17,000 miles) above the equator a week on Friday ? a record close approach for an object of its size.
The asteroid 2012 DA14 will fly extremely close to Earth on Friday, Feb. 15, but poses no risk of impacting our planet. It may, however, be visible in backyard telescopes if you know when and where to look, but will be a stargazing challenge, NASA says.
Discovered last year, asteroid 2012 DA14 is about half the size of a football field and will approach within 17,200 miles (27,680 kilometers) of Earth when it flies by during its close encounter.
NASA scientists have called the event a record-setting flyby for an asteroid of 2012 DA14's size. The asteroid is about the same size as the object that exploded over Russia's Siberia in 1908 in what scientists now call the Tunguska Event.
