Close Shave: Asteroid To Buzz Earth This Week



  • An asteroid the size of an office building will zoom close by Earth next week, but it's not on a collision course, NASA says.

    Still, some people think this near-miss should serve as a wake-up call.

    "It's a warning shot across our bow that we are flying around the solar system in a shooting gallery," says Ed Lu, a former astronaut and head of the B612 Foundation, a nonprofit dedicated to protecting humanity from asteroids.

    The asteroid known as 2012 DA14 was first spotted last year by astronomers in Spain. It's thought to be about 150 feet across and made of rock.

    It will whiz past Earth on Feb. 15, going about 5 miles per second. At its closest approach, it will be only about 17,200 miles above the surface of our planet. That's far nearer to us than the moon, and even closer than some weather and communications satellites.

    NASA officials say this event is one for the record books — the first time scientists have been able to predict something so big coming so close.

    "There really hasn't been a close approach that we know about for an object of this size," says Donald Yeomans, manager of the Near Earth Object Program Office at NASA's Jet Propulsion Laboratory in Pasadena, Calif.

    It will come closer than satellites in a geosynchronous orbit around 22,000 miles up, but is extremely unlikely to hit any of those as it goes by.

    "This asteroid seems to be passing in the sweet spot between the GPS satellites and the communications and weather satellites," Yeomans says.

    “ There really hasn't been a close approach that we know about for an object of this size.

    Its flight path is well-understood enough to know that there's no chance it will hit the Earth.

    Lets witness the sad demise of the Jinns who tried to listen the news of the Heavens.
