Fortunately the Daily Mail is infamous for leaving out often important context, like, you know, the actual chances and time line of possibility for events like this. It was a similar story when a tsunami was meant to hit the west coast of the States and Canada. A worst case scenario could have been 'soon' and 'catastrophic' - but the reality was that it had something like a 50% (based off geological estimations) chance of happening over the next hundred years.
Not exactly something to worry about. Hell, various telescopes are on constant vigil of asteroids which are constantly flying around our planet with again, catastrophic implications.
So it's interesting to know, but certainly nothing to worry about. After all, if it happens tomorrow morning, what would you be able to do about it anyway?
