So I was hitting random on XKCD and this one came up: https://xkcd.com/1626/ I've seen discussions elsewhere about the delta-V needed to send something into the sun, and while I have no idea what the delta-V of the typical ICBM is, I doubt they even have enough to reach LEO since they're a weapon that's intended to hit a target somewhere else on the Earth. But just as a thought experiment, what if the XKCD scenario happened? Say you launched them retrograde to Earth's orbit. Would they just just rain down on Earth again and kill everyone? How much delta-V would be needed for one to escape Earth and not come back? (Not necessarily hitting the Sun, just ending up in a Solar orbit that never intersects Earth again).
