NEO asteroid 2012 LZ1 is NOT going to hit the Earth and will not even be visible except by telescope. The Internet is buzzing with hype about impending doom. Relax, this one is a clear miss!
The estimated diameter of 2012 LZ1 is 310-690 meters, and it will pass at 14.2 Lunar Distance (LD), that is 14.2 times the distance between the Earth and the Moon. It is NOT a close call.
