  1. Question

    If Jupiter's moon Europa has so much Methane on it, why does it not explode (let's say if a comet or something with fire hit it)?

    I am having trouble understanding your question. (1) I don't know of any evidence that Europa has a lot of methane either on it or in it. (2) A comet is not on fire; in fact, comets are very cold and composed mostly of various ices. (3) For methane or any similar chemical to burn or explode, there must be plentiful oxygen, but oxygen is very rare on both Europa and comets.
