Asteroid 2014 AA, the first asteroid discovery of the year, was spotted by astronomers using the Mt. Lemmon Survey telescope in Arizona. As shrewdly pointed out by Bad Astronomer Phil Plait, the asteroid was the approximate size of a couch - measuring only a couple of meters across. That's around one-half of a Mini Cooper, whichever takes your fancy. But whatever your preferred size comparison, the outcome was likely the same; the asteroid burned up on atmospheric entry as a meteor.
This might have provided a nice visual spectacle only a day after New Years, but 2014 AA is notable as being the first pre-impact discovery of an asteroid since 2008.
Comment: Obviously this article is really trying hard to put forward a "nothing to worry about, go back to sleep" schtick - here's the real story: First observed 'Near Earth Object' this year, named asteroid '2014 AA', impacted planet several hours later!
