ASTEROID APOCALYPSE ~ Professor Michio Kaku

It's impossible to see every rock that's flying around in outer space. The larger ones are pretty easily spotted but the smaller ones are most of the time more or less invisible until they're really close.Professor Michio Kaku speaks about the increasing need for an early warning system due to the inevitable event in which Earth is struck by another large asteroid.

The DA14 -- an asteroid a half a football field across, traveling at a blistering 4.8 miles per second -- is expected to pass within just 17,200 miles of Earth on Friday, a record close encounter that will carry it well inside the orbits of communications satellites. Faced with questions about the asteroid and safety on Earth, Kaku pointed to the moon's pockmarked look as a sign of what's spinning around in space: "The moon is pockmarked because there are a million objects of that size near the orbit of the planet Earth." He added, "The Earth is moving in a cosmic shooting gallery."
