Alpha Centauri Secrets: Is It Anything Like Our Solar System?

- In our galaxy, exist billions of stars that could harbor life; many of these stars are relatively close to our solar system. However, the closest of all is the Alpha Centauri star system.
This system is made up of 3 gravitationally linked stars, and in the future, it will undoubtedly be the first place that humanity will visit when I manage to leave the solar system, but... How can three stars be orbiting each other without colliding, and what similarities does this star system have? With ours? Does it also have rocky and gaseous planets like the ones that orbit the Sun?
Join us to find out!
A long trip
Despite Alpha Centauri is the closest star system to ours, humanity will not be able to visit this place for at least this century since spacecraft technology cannot cover such enormous distances in a human lifetime.
As an example, the Voyager probes are the spacecraft created by humanity that have gone the farthest; they are currently at the edges of the solar system traveling at a speed of 38,000 miles per hour or 61,200 kilometers per hour, but although This speed is surprising to us, traveling at this speed the Voyager probes would take tens of thousands of years to reach Alpha Centauri.
So if you were considering visiting this star system, we are sorry to break your illusions. That will not be possible now.
However, we can study this solar system with our most powerful telescopes. Thanks to this, we have discovered essential things with which we now know that this place is very different from our solar system.
Location
Located at a distance of 4.5 light-years from Earth, the Alpha Centauri star system is moving in a direction similar to the direction the Sun moves around the galaxy.
The orbital speed of the Sun and Alpha Centauri around the galactic center is estimated to be around 220 kilometers per second (500,000 miles per hour). Both stars and other stars in the solar neighborhood take approximately 200-250 million years to complete one orbit around the galactic center.
It is important to note that the orbital motion of the stars around the galaxy is not linear but a motion in an elliptical orbit. Also, stars' exact speeds and trajectories can vary due to gravitational interactions with other stars and local gravitational disturbances.

It's a dam good thing Alph Centauri doesn't have any giant stars because if it went supernova the earth would be in trouble!
Good point. Einstein said nothing with any mass can travel at light speed. I wonder if any of their stars went into supernova how long would it take to reach our solar system 🤔
@@alanbrady7116 Yes! I think it would basically be 4.3 years from the instant the photons were released.
were already in trouble mate. we havnt learnt to live together in peace,
@@peterwhite5654 your 💯 correct. I fear it may take long time, as in generations. Religion, culture and political differences seem to be the main issues that divide us. Mass Immigration I regret to say is central to the problems in my country
@@peterwhite5654 True that!
Awesome video. Keep up the great work! A+
More good questions - thanks Team Curious ❤
Watch out for the Trisolarans.

It's interesting that as fast as the Voyager probes are moving, they're going so slow that for part of the Earth's path around the sun, Earth is actually catching up to the probes because Earth is moving through space almost twice as fast as the probes are moving.
To me it would be much stranger and weirder if a and b did not have any exoplanets
Great video !
This is overly verbose, almost as if two videos of the same system were combined. I had a strange sense of deja vu at about the half way point. Just my opinion.
If temperatures in Farenheit are given with 2 significant figures, the conversions to Celsius should do the same!
The Centuari solar system is a binary solar system comprised of two suns, a larger and more massive Alpha Centuari, and the outer sun, much smaller, Proxima Centuari, because its orbit brings it closer to Earth than Alpha Cen. It is also currently on that side of the orbit.
Love it
What if we establish a refinery station on planet Mars that will allow us to travel to proxima centauri
I thought I'd add it 1st coz it's such a quick whitted non-overused joke....

Alpha Centauri is a star, right? From what I know, the stars do not have any possible way to host any kind of life.
They’re talking about anything planets orbiting the star

Okay
Very repetitive video.
This video is odd: the same statistics about the stars are repeated over and over at strange jarring intervals. There are multiple errors, such as Alpha Centauri B being "36% as bright as our sun", despite also saying it is only slightly less bright. It is called an "orange dwarf star" despite being described as a G and not K type star. Very poor editing, and an obvious cut and paste of data someone did not really understand? The narrator sounds like an AI, not a human, and the "writer" does not appear to be a native English speaker.
Please, this video had so much potential to be above average. Might I suggest (a) edit BEFORE posting? (b) do your research BEFORE posting, and (c)get a native English speaker to help, and find a native English speaker and not a bot to narrate? ;)
There likely are some truths in this video but the script writer and speaker don't know what they are. Anyone subscribing, believe things said here at your own peril. If the brand owner/producer of this content either doesn't notice or doesn't care that the first half of the video contradicts the second half (in comparing the size of AC-A with our sun (SOL)) then the most positive thing I can say is "Insane" is a fitting channel name. Curiosity should be dropped from this channel name since no one was curious enough to figure out whether AC-A's diameter is 1.5 times the diameter of the sun - Or- whether its radius is 23% bigger than the sun. I'm thinking 'Insane Monetization" would be a better channel name.
I was curious and neither is correct. SERIOUSLY: With the sun's diameter about 696,342 Km and AC-A at 905,245Km, one could say it's diameter is is very nearly 1.3 times that of the sun. There are more errors and contradictions mentioned here in other comments.
I heard even MORE errors in this video near its end, so BAD that I unsubscribed! Do note that a tidally locked planet in no way needs to have its axis of rotation perpendicular to the plane of rotation to be tidally locked! DO YOUR RESEARCH, PLEASE!
