Let’s talk about the possibilities of collisions with the Earth.

Actually, our Earth is being hit all the time by cosmic dust and meteors. More often than not, these will fall into the atmosphere and burn up, producing a streak of light in the sky we call a “shooting star.”  But sometimes the chunks are big enough so that part of the original chunk gets through the atmosphere.  Anywhere between 5 – 300 metric tons of dust and meteors strike the Earth per day!
