ASTEROID EMERGENCIES

When the going gets tough, the tough get asteroids. Here's your emergency guide:

Scenario 1: Asteroid is on a collision course with Earth

Action Item: Panic, but only slightly. Send a strongly-worded letter to the asteroid, expressing your deep disappointment in its life choices.

Scenario 2: Asteroid is too close to be seen from space

Action Item: Don't. Just don't. It's too late now, anyway.

Scenario 3: Asteroid is too big to be ignored

Action Item: Build an asteroid-sized wall. Good luck with that.
