“No Earth impact is possible,” said Donald Yeomans, an astronomer with the US space agency.
Smile and wave. If it did hit us, and it landed on the dirt somewhere, it would make a hole about the size of meteor crater in Arizona. BOOM! Which wouldn’t be a horrible problem. It might even block some sunlight for a while and cool us down a bit, who knows?
What I’d like to know is – where are the solid gold asteroids? What’s with all the nickel and iron? Yeah, sure, iron is formed during the last cycle of a supernova, and therefore it’s much more plentiful than gold which is formed during the supernova explosion itself, but there must be some big ass chunks of gold out there somewhere.
If the asteroid were solid gold, would the governments of Earth be more interested in probing it? Maybe even want to try and stop it or mine it somehow? Think of all that gold! If that asteroid were solid gold, it would be more gold than we have access to now on the entire planet!
But then, we’d probably fight over it wouldn’t we? I mean, if a giant gold asteroid crashed into say… Kansas or something, imagine all the people rushing out there looking for chunks of it. It would be a war zone. People would be staking claims. The government would cordon off the area and call out the national guard to force back the crowds of desperate treasure seekers.
Anyway, I suspect that for a long time, the only gold we’re going to be getting out of asteroids is investment money obtained by companies saying they’re going to mine gold out of asteroids. That’s what I’d call a “long-term” investment.
