That reminds me of this miniseries I just watched a few months ago on DVD from Netflix. It's about a meteor shower that comes by, and a large, rogue piece of a highly mangetic brown dwarf is in the debris, but they don't see it until it is about to impact the moon, and then it hits, and blah blah blah. But every time I think of how they say that art imitates (or hints at) doom to come, and it relates to something hitting the moon, I think of this one...
