Discovered on December 9th, asteroid 2012 XE54 flew by planet Earth so close on December 11th that, any closer, and we'd all be dead.

Astronomers estimate that 2012 XE54 is about 120 feet (36 meters) wide -- big enough to cause substantial damage if it slams into Earth someday. An object of similar size flattened 800 square miles (2,000 square km) of forest when it exploded above Siberia's Podkamennaya Tunguska River in 1908.
