On an asteroid passing near Earth:
"Now, this one that hit Russia, yes, it tore up the town a bit, but it's not disrupting civilization. If you get asteroids about a kilometer in size, those are large enough and carry enough energy into our system to disrupt transportation, communication, the food chains, and that can be a really bad day on Earth."
Do you think Neil DeGrasse Tyson or Bill Nye said it?
How close was it?
