You have to be worried about the possibility of a metor strike on the earth. Although it has not happened in my life line ,there has been occasions and the odds are high that one will .This “fly-by” by an asteroid the size of a city block is set to fly by Earth Thursday (June 14), and you may be able to watch it happen live.
The near-Earth asteroid 2012 LZ1, which astronomers think is about 1,650 feet (500 meters) wide, will come within 14 lunar distances of Earth Thursday evening. While there’s no danger of an impact on this pass, the huge space rock may come close enough to be caught on camera.
That’s what the team running the Slooh Space Camera thinks, anyway. The online skywatching service will train a telescope on the Canary Islands on 2012 LZ1 and stream the footage live, beginning at 8:00 p.m. EDT Thursday (0000 GMT Friday).
You can watch the asteroid flyby on Slooh’s website, at events.slooh.com.
The scary bit is that it has only been found in the last few weeks. If the big one does come at us ; the chances are that it will be sudden .
