Watch a Giant Asteroid Flying by Earth Tonight; live now: http://events.slooh.com/
News outlets are reporting the asteroid is “the size of a city block.”
Astronomers are estimating this thing is about 1,650 feet wide, which is quite big.
The asteroid is named 2012 LZ1. It will come within 14 lunar distances of Earth Thursday evening.
Here’s a great visual from Wikipedia to put lunar distance into perspective. (As the name implies, it’s a measurement of the distance between the Earth and its moon.)








WOW!!!
