But still. If the sun is indeed oscillating relative to the galactic plane: Would that not indicate that other stars are doing the same? Isn't it likely that other stars are oscillating with a deviant frequency and thus are constantly travel away or towards our sun? Hmm... A possible question may be: What do you mean with "not much"? Is "not much" enough to create the need to constantly update the star maps (because "not much" on a cosmic scale could mean a lot)?

Thanks for clarification. As far as I understand you in a "star trek" like setting with technology like the warp drive the relative motion of a destination star would not be a problem due to the short amount of time needed to reach it.

Hi astromax. Thanks for your answer! According to your answer and the (very interesting) link you provided, stars are indeed changing there relative positions to one another but these changes occur over long periods of time (although star systems are traveling at high speeds). Is it save to assume that therefore these changes are not relevant for, lets say, future space navigation? Like the continental drifts are not relevant for today's navigation?
