"Okay, kiddos, let's ignore pieces of planets hitting us, even though we're not sure the atmosphere would stop them as they are NOT made of ice. Let's talk about the sudden change in gravity going one way or the other. As it was said before, if the Earth was off it's orbit by just a tiny bit in either direction, we would not be here. Imagine, for a minute, what it would mean for us, if the gravity surrounding Earth changed. If Earth got nudged that tiny bit - or more - in either direction."
