|2012 DA14 size relative to the shuttle|
Is this the end? Is it a planet-killer? Will we go the way of the dinosaurs? No, sorry, the asteroid will miss us and some of you will still need to buy some chocolates and/or flowers if that is your thing.

ADDENDUM: Meteor strike in Russia injured more than 400 people, 15 Feb. 2013. According to Don Yeomans, head of NASA's Near-Earth Object Program "This bolide event probably had nothing to do with the upcoming close Earth approach of asteroid 2012 DA14"
- 2012 DA14 will pass within 18K miles of Earth between the geosynchronous satellites and the ISS (the moon orbits at 239K miles) making this the closest approach of an asteroid to Earth in recorded history
- It is 50m long (one half this size created the 1-mile across Meteor Crater in Arizona 50K years ago) or half a football field
- If it were to hit Earth (which it is NOT), the blast would roughly equal that of the Tunguska event in 1908
