12-12-12, asteroid Toutatis buzzing Earth tonight. North Korea's and US rockets launched yesterday. Coincidence?

A giant asteroid will make a flyby of Earth over the next few days, and armchair astronomers can watch the action live on their computers.

The near-Earth asteroid 4179 Toutatis, which is about 3 miles wide, will zoom within 4.3 million miles of Earth during its closest approach early Wednesday morning, Dec. 12. That's too far away to pose any impact threat on this pass, but close enough to put on a pretty good show through top-notch telescopes, researchers say.
