Fortunately (or unfortunately, depending on your feelings toward our sewer of a world), the rogue asteroid is pretty small, around 60 feet wide. Heck, even if it did hit us, one that puny wouldn't even wipe out a medium sized city, much less our whole sorry civilization. Not to mention the fact that there was actually an even closer fly-by back in early 2013.
The really worrisome part of the story is that the asteroid wasn't discovered until August 31st, 2014– a scant seven days before its flyby! Hopefully when the big extinction-level rock is heading toward our globe, we'll have a bit more warning. You know, for panicking, looting and uncontrollably shrieking and such.
