A large asteroid will pass by Earth tonight (December 12), and although it cannot be seen with the naked eye, astronomy aficionados can watch the phenomenon live on their computers.
The asteroid, called 4179 Toutatis, is about 5.5 kilometers wide, and will approach our planet tonight to a distance of about 6.9 million kilometers. The distance is not close enough to pose a threat to Earth, and the celestial body is not large enough to be seen with the naked eye, but large astronomical telescopes would be able to get a good look. The following websites will broadcast the event live: Slooh Space Camera and Virtual Telescope Project.
According to Slooh Space Camera the best time to watch will be within about 5 hours from now (5 PM EST).
