I'm pretty sure she doesn't move planets, but she will punch a moon away from a spaceship. That's what Kevin Feige said, and I can easily see how that turned into "she can move planets." Still ludicrously OP, but with Thor's star feat that seems to be the direction the MCU is headed.
Does Vision have any strength feats at all? I mean we can speculate given the feats we've seen from Vibranium that someone with Vibranium muscles would be extremely strong but there isn't much to go off.
