      Google doodles Earth's close shave with Asteroid 2012 DA14
      TOI Tech & Agencies | Feb 15, 2013, 01.03 PM IST

      NEW DELHI: Google has made a doodle for Earth's close shave with Asteroid
      2012 DA14, which will pass by the planet tonight. The doodle shows the
      second 'G' in the company's logo moving aside in a seemingly alarming manner
      as an asteroid passes by its spot.

      Asteroid 2012 DA14 is a newly-discovered asteroid about half the size of a
      football field will pass nearer to Earth than any other known object of its
      size. It will cross paths with the planet on February 16, 2012 at 12:55 am
      IST (19:24 GMT), giving scientists a rare opportunity for close-up
      observations without launching a probe. In addition to trying to determine
      what minerals it contains, which is of potential commercial interest as well
      as scientific, astronomers want to learn more about its spin rate. The
      information not only will be useful to plotting DA14's future visits but
      could help engineers develop techniques to thwart more threatening

      At its closest approach, it will pass about 27,520km (17,200 miles) above
      the planet, bringing it nearer than the networks of television and weather
      satellites that ring the planet. The astronomical body will travel at a
      speed of 13km (8 miles) per second.

      Although Asteroid 2012 DA14 is the largest known object of its size to pass
      this close, scientists say there is no chance of an impact, this week or in
      the foreseeable future. Currently, DA14 matches Earth's year-long orbit
      around the sun, but after Friday's encounter its flight path will change,
      said astronomer Donald Yeomans, with Nasa's Jet Propulsion Laboratory in
      Pasadena, California. The non-profit Space Data Association, which tracks
      satellites for potential collisions, analyzed the asteroid's projected path
      and determined no spacecraft would be in its way.
