Asteroid

An asteroid almost hit the earth on November 8, 2011. It was the size of an aircraft carrier, the big boats that planes land on. A similar sized asteroid was responsible for the destruction of the dinosaurs. If it had hit the earth, it would have been disastrous. It flew past Earth, coming within the orbit, and almost hit the moon. If it had hit the moon, the tides would be forever changed, and tsunamis would be hitting almost every shore there is. It would also probably effect us.
Have you ever heard someone say that full moons are when people go crazy? There is a theory that the moon has a pull over us because we are made up of mostly water. If the asteroid had hit the moon, there is no telling what would happen.
I found out today (November 15, 2011) about it. Because I knew it was already past, I didn't think it was that big of a deal. If it was, wouldn't I have heard of it before? I know it came REALLY close to hitting us, but it didn't hit us. So, what was the big deal?
