Regardless of how many discover it, if it's determined that this object will destroy all higher order life on Earth, what would be your protocol? After, of course, you recheck your numbers and sh*t your pants.

Nearby objects are being discovered all the time, and didn't something pretty massive just hit Jupiter this year? How long have we had technology looking for this stuff? I am saying that we'll probably see it coming from far away, but I'm also saying it's possible that some very large objects with some very large abnormal orbits are out of our discoverable reach at the moment. Don't you think? My question remains: how would you disseminate this information?
