CNN.com - Giant asteroid could hit Earth in 2014

Well, I am not really into science but I am fascinated by space and, of course, headlines such as these.
The funny thing is, that just after it says that a GIANT asteroid could hit earth it says:
But for those fearing Armageddon, don't be alarmed -- the chances of a catastrophic collision are just one in 909,000.
Then why write a headline like that?
