An asteroid lost to scientists over a decade ago is back, and while the chances are slim, it could strike Earth with the force of 2.6 billion tons of TNT this year.
NASA said in a statement to MSN that asteroid FT3, first discovered and then lost in 2007, has a 1 in 10 million chance of colliding with Earth on October 5. The force of such a collision wouldn't be planet-ending, but it could significantly damage a continent.
Scientists say it's very likely we'll escape just fine, but WPXI notes in a report that even sometimes people win the billion-dollar lottery, and those odds are 1 in 300 million.
The real threat to Earth, MSN reports, is asteroid 29075. That asteroid would hit the planet with the force of 75 billion tons of TNT, and yes, experts say that's enough to end humanity.
That asteroid has a 1 in 34,500, chance of hitting Earth on March 16, 2880.
