Did you know that the Earth was almost struck by an asteroid this week? Unless you follow science news closely, you may have missed it.
The asteroid, designated 2009 DD45, is less than a third of a football field in diameter (approximately 20-30 yards). After watching movies like Armageddon and Deep Impact, that seems pretty small, doesn't it? It's no Texas-sized Global Killer like in Armageddon.
The impact of 2009 DD45 would still have been disastrous. "The force of multi-megaton nuclear blast," wrote one reporter. Striking a city would have leveled it and killed millions. Striking the ocean would have caused a horrible tsunami that devastated coastlines.
Yikes!
