<p>Yes the Alpha Centauri system is moving closer and it's not the only one. Barnard's Star, the fastest moving star in our skies, will get close sooner. The major concern is whether or not they will get close enough to disrupt our Oort cloud.</p>

<p>This <a href="https://commons.wikimedia.org/wiki/File:Near-stars-past-future-en.svg" rel="nofollow noreferrer">diagram</a> shows the relative distance of various nearby stars over time.

<p>Yes, it's moving closer.</p>

<p>In about 30,000 years Alpha Centauri will be 3 (and change) light years away, then it will start moving further away.  </p>

<p>The closest star system after our sun is Alpha Centauri, a three star system with Proxima Centauri, a red dwarf, slightly closer to us than the other 2, around 4.3 light years. I tried <a href="https://en.wikipedia.org/wiki/Alpha_Centauri" rel="nofollow noreferrer">Wikipedia</a> and <a href="https://www.space.com/32560-alpha-centauri-what-we-know.html" rel="nofollow noreferrer">other artic</a>les that describe Alpha Centauri and there is plenty of information, but no where could a find an answer to said question.  </p>

<p>My presumption is that if the distance is measurable, so should the variance in this distance.</p>

# Is the Alpha Centauri star system moving closer to us?

(Asked by: username_0 on 2017-11-08)

The closest star system after our sun is Alpha Centauri, a three star system with Proxima Centauri, a red dwarf, slightly closer to us than the other 2, around 4.3 light years. I tried [Wikipedia](https://en.wikipedia.org/wiki/Alpha_Centauri) and [other artic](https://www.space.com/32560-alpha-centauri-what-we-know.html)les that describe Alpha Centauri and there is plenty of information, but no where could a find an answer to said question.

My presumption is that if the distance is measurable, so should the variance in this distance.

Yes, it's moving closer.

Per [Wikipedia](https://en.wikipedia.org/wiki/List_of_nearest_stars_and_brown_dwarfs#/media/File:Near-stars-past-future-en.svg).

[Source](https://en.wikipedia.org/wiki/List_of_nearest_stars_and_brown_dwarfs#Future_and_past).

In about 30,000 years Alpha Centauri will be 3 (and change) light years away, then it will start moving further away.
