The Coming Close Calls

With the double shot of a meteor strike and a close asteroid fly-by last week, I began to wonder just how many of these near Earth objects are out there that we already know about, like 2012 DA14 and try not to think of those that are hidden waiting to strike, like the meteor in Chelyabinsk.  Today’s infographic is a comparison of those objects we know are coming within the next 200 years that will pass between the Earth and the moon, showing both their relative sizes and the anticipated dates of arrival.  [VIA]
