<p>This image should give you a good idea of the distances of stars relative to the Sun over the next 80,000 years (and the past 20,000 years).</p>

<p>Proxima Centauri remains the nearest star to us for about 25 thousand years, at which point Alpha Centauri passes it. ~7.5 thousand years after that, Ross 248 swings in closer.

I don't understand your "aside" about the stars orbiting the galaxy. Do you have any more info about the source of that animation? Tracking stars 0.1 million years in time seems feasible. But 250 million years around the galaxy, that's really impressive.

<p>After reading about <a href="http://www.solstation.com/stars/barnards.htm" rel="noreferrer">Barnard's Star</a> and how it's approaching us 140 km/sec, I'm curious if there are any visualizations of how the nearest stars to Sol will be moving over the next 100k years or so. </p>

<p>I'm amazed that Barnard's Star, currently 6 light years away, will be only 3.8 light years away in about 9,800 years. It's really moving!</p>

Have you seen https://commons.wikimedia.org/wiki/File:Near-stars-past-future-en.svg? It's not an animation, but it does help.

@HDE226868 you should post that as an answer, the question asked for a visualisation, not specifically an animation

After reading about [Barnard's Star](http://www.solstation.com/stars/barnards.htm) and how it's approaching us 140 km/sec, I'm curious if there are any visualizations of how the nearest stars to Sol will be moving over the next 100k years or so.

I'm amazed that Barnard's Star, currently 6 light years away, will be only 3.8 light years away in about 9,800 years. It's really moving!
