You may have seen the scary headlines. You may have read those alarming emails. But do you believe it? Just in case, NASA has issued the facts about a comet called Elenin. And no, these aren't the "facts" doomsayers will tell you.

It's too small and its closest approach to Earth will bring it 90 times the Earth-moon distance. 90 times the Earth-moon distance. That's a whopping 35 million kilometers (22 million miles) away. Could there be any conceivable impact to our everyday lives by this dirty snowball?
