How Far Away Is Our Nearest Star System? Alpha Centauri

Thank you for using the World Metric System!

Wow dude!! Been watching your channel for nearly a year now and this is the first time I saw you and it's probably the oldest video I've watched from you so far.. lol nice to put a face to the voice!!

Ok, I have shown this to sooooo many people because this is the only way they actually understand the distances in space and how unrealistic it is to imagine travelling between stars.- in a human life span scale, where is this place you are at? cannot be UK, since they drive on the right. but you got the british accent and palxe as a scotchman.

Alpha Centauri system is around 4.3 light years away. We on Earth will see the star system 4.3 years ago.
Imagine some alien lifes out there on Alpha Centauri and observe Earth from a distance.
They will not know the Covid-19 pandemic is hitting us and they will still observe no human beings are wearing masks.
Because they will observe Earth as 4.3 years ago from 2022, roughly around December 2017 - January 2018.

My guess is 7 or so KM

Congrats on 1 million Astrum! You do a really great job with your videos and earned every subscriber.

Well done.

Mow the lawn! Lol

I knew you were in Switzerland!
And I was way off in my guess, thinking it was about 12km from the Sun...
I then thought 20km...
But then I rethought and you're going 30km for this example!?
Yes! Third guess was right, wow!
Great video, this really gives some perspective on the huge [to us] distances betwen the objects in our Galaxy, much less the Universe!

Please post more videos about Alpha Centauri and are there any planets there?

Best demonstration of the sheer immensity of the Universe. Well done, Alex. That it took us 9.5 years to get from the Earth grain of sand to the Pluto grain of sand really boggles the mind how far our closest star is.

Who cares about the nearest star when you're in Switzerland!!! My goodness!!! It looks like heaven...😱😱😱

Big question ??? How did all this START???

I don't know, but I'd say the sun is much too close for your eyes.
If you were where I am, you'd go blind.

Nice, wonder what I did back then only a few kilometers apart from you ^^. Were you in switzerland for studying (university of Bern for example) or for other reasons?

Kindest regards from Interlaken🙌🏻

It's always nice to put a face with a voice!

I'd enjoy this more if I wasn't a complete idiot and knew how many centimeters were in a foot.

I knew you were always smiling!

Fantastic Alex, thank you for another brilliant video!

WTF! is this irritating sh*t ass music...had to turn off video.

Since alpha centauri is 4.16 light years away Alex is driving like 100000 times the speed of light.

Wow, that is absolutely incredible. And you are incredible too for showing us this unbelievable recreation of our reality. Thank you so very much for your efforts, I love ❤️ all your videos!! You are an awesome person ❤️. Great video, I also thumbs-up it too!

I'm binge watching a whole bunch of your videos right now. I won't forget the thumbs up either for all of them to help with the algorithm too. Thumbs-up for all!!! Love ❤️ your videos man!!!

i've seen this video before, years ago, but it still blows me away!

newbie question: how did they figure out that alpha centuri is the closet star to us?

Wait theaa . . Can u call the goblin . Perhaps their . . 🏝️🌈🌄😀

One of the most inspiring videos about space and interstellar travel I've seen. While driving a lot of thought boggle the mind: how pluto is only meters afar, how little we explored the space in radius of even these meters from Earths, how precise we'll need to be to reach this Alpha Centauri grain of dust, or rather even 2-3 grains which are also only meters apart. Thinking how much time of the video even at 5x speed it took to reach the nearest star I understand why Sci-Fi always just handwaves interstellar travel one way or another. ❤

4 light years doesn't sound so near now does it

Blows my mind we can see things that far away! Thankyou for showing us the beautiful area. Really is a mind blowing amount if distance. And to think our sun is a bit bigger than 1 cm. 🤯

30 km

Right, has everyone got their packed lunch? And a spare coat? I don't know what the weather will be like at Alpha Centauri....

I think it would be pretty cool if your real name was Gary Astrum

So Alpha Centauri was at an apartment complex in Switzerland all along!

Everytime I think I have some mental understanding of how far away things are I find myself confounded once more after watching a video like this.
Thanks

What would be the distance between the Milky Way and the closest galaxy, the Andromeda?

Great to see the face behind the voice Alex.
Once again you have blown my mind!

GOD and speed of mind can reach that distance, amazing measurement, from. Iloilo city Philippines,

I don’t care about solar system distance. Your town is beautiful. Where is it?

And with today's latest technology it would only take 300,000 years to reach the next star. So keep dreaming!

We will never leave the solar system. It’s two damn far away.

This video just boggles my mind and does a very good job of describing and explaining ratios

Solar system is very tiny compared to the galaxy!!!! 🌌

It would be nice 👍 to travel at the speed of light 💡 and travel 🧳 to Alpha Centauri in 4 years 3 months

Can't we just send mutiple beams of light ✨️ and try to find a rock mirror to send it back ? Whit curent technology i bet there is a solution just to have a picture of some kind .

This video only shows distance, but the real test is to imagine space, which is not a distance, but a huge sphere. Our solar system is stretching out in all three dimensions. I think as earth bound creatures we can't fathom it at all. If you would go above to show the distance to Proxima Centauri, you will very soon leave the ISS behind.

At 1mm per Sun Diameter, 10.7cm per AU, or 6.8km per light year, even our own galaxy spans the orbit of the moon around the earth!

Absolutely nuts. This is as close as my mind can get to understanding the scale of the universe. Sun is a grain of sand, the nearest grain is 30kms away, and there are trillions of them out there. Goodbye brain.

Hi

Well, now I've been able to view the oldest 20videos you posted. Can't wait to do more.
