This bogus thing is made of the same material as the Meteor Crater in Arizona, and it's totally gonna get within a thousandth of an AU to our sacred planet! If this destroys the Earth, that would have a majorly bad effect on the rain forest! Mister President, you gotta give us, like 150 billion dollars or so, and create like a new government agency to save us all! Anything else would be bad karma!
