Another Asteroid Close Encounter

About a month ago - January 13th to be exact - I posted an entry about asteroids and PHOs (potentially hazardous objects).   I wasn't expecting to add another entry on the subject so soon.   However, I just learned of another close encounter - even closer than the one I reported on previously. 

This asteroid is called 2012 DA14. It's about fifty meters across. On Friday, February 15, 2013,  DA14 will miss planet Earth by about 15 minuites, passing within 17,500 miles.  In celestial terms, that is an exceedingly close shave.

Here is a video of science educator Bill Nye talking about asteroid DA14.
