Far too close to have NOT BEEN NOTICED WHATSOEVER. We have thousands of eyes looking for these NEOs (Near Earth Objects) and yet, we let this MONSTER get by totally unnoticed. I thought my parents were kidding when they said that this happened. I don’t know… but maybe we should be looking a TAD closer at these potential CIVILIZATION ENDING objects more carefully.
I live 18 miles from the Pacific Ocean. It’s the largest ocean on the planet. It has, by far, the most open surface area of water ANYWHERE. If one of these fuckers hits in the middle of the ocean, the tsunami generated would kill me, and every other person living on the west coast of the US. There would be no escaping the wave. I might survive if I started driving IMMEDIATELY after impact, and took off for the 4000 feet above sea level mountains. Even then, a shock-wave tsunami might stretch thousands of feet into the sky, and go inland for miles before losing inertia.
Now I have a real reason to have a backup plan. But really, if THAT is the way I go out, It’s not too bad a way to go. I’d LIKE to survive, but he probability is pretty low.
Time will tell.
It’s pretty difficult to locate a piece of spinning soot-covered, non-reflective black rock in the vast empty dark of space. We only REALLY notice NEOs when they obstruct something. That’s not a great way to find our potential doom, methinks. Maybe we could spend some of our budget on making sure that does not happen…?
