This comet called Comet Elenin is causing quite a buzz right now.
Its course will pass very close to Earth in fall, and it's got the so-called "2012 believers" buzzed up, them talking about the "end" and all that.
Nah, in my opinion, it won't hit us. When you think of the solar system, you'll get an mental image of something like this.
So, there's a LOT of space between planets. And the possibility of a comet hitting us?
True, there have been a few giant impacts to Earth in the past. But that's very, very, very, very rare.
So, we're safe.
That's what I think, at least.
