2011 AG5

The asteroid 2011 AG5, discovered just last year, is the new body most likely to crash into Earth in the near future. The date is February 5, 2040. Of course, since it was just found last year, the asteroid has not yet been observed through one complete orbit. Once it is, astronomers will have a better idea of just how likely a collision actually is.

At 460 feet across, 2011 AG5 is not a Doomsday rock, but, depending on where it hit, a collision could still result in a huge disaster.
