@@kryts27 If somehow it had managed to escape the earth’s atmosphere, the atomic manhole cover could be more than 900 AU away by now. If we used all the technology we have at our disposal it would be comically easy to send a probe that far out at those speeds intentionally. It’s not like it’s unprecedented either - We’ve send nuclear reactors and generators into space dozens of times. It’s not a large step to use them to power propulsion - which we’ve already successfully experimented with on earth.
A point worth noting, that no one ever seems to, when describing Proxima as the closest star to the earth is that, if it is indeed in orbit around the Alpha pair it will eventually travel to the other side of the system, beyond the Alpha pair from our perspective At which point the Alpha pair will be the closest stars to earth. So it would be more accurate to say that Proxima is "currently" the closest star to earth.
Well that will always change, the orbital period of proxima centauri is 550,000 years so alpha centauri will also have moved away and been replaced by a closer star by then
I love this channel so much, I've always been obsessed with space but either videos are full of lies, are super old, or AI slop... articles also are just hard to read . keep up the good work!
The closest planets to us outside our solar system. Blows my mind. We have grown up with our planets and there is a whole other story in this neighbour.
Fahrenheit can be understood more easily if you think of it basically as a 0-100 scale. 0 being about the coldest outdoor temperature you've commonly experienced and 100 being the hottest. That'll get you pretty much in the ballpark. 0 is a straight up blizzard. 10 is cold as fuck. 20-30 is like the mountains when you're skiing. 32 water freezes. 40 is like late season spring skiing. 50 is a slightly chilly day. 60 is brisk but nice. 70 is t shirt weather. 80 is hot. 90 is uncomfortably hot. 100 is a heat wave. That's how I explain it to my russian roommate and it's helped him to at least understand what people are talking about when they use Fahrenheit. Hope it helps you lol. America is weird
Nope, two body. Proxima Centauri orbits the barycentre of the other two stars. He said it. Why the obsession with 3 body? It's unstable orbits are rare in the Universe
If Alpha Centauri Ab[n] was habitable and actually inhabited, that would be pretty crazy. I would just kinda have to go forward assuming literally everything that can have life does have life until proven otherwise. :P
“Habitable” only applies to hypothetical local life of course. By the time humans have the tech to reach there, living there will probably be a trivial problem. We will probably have nations in the Oort Cloud by then.
Why should anyone ever live in the Oort Cloud? It's too far away from the Sun to get energy from solar panels and since those Oort objects are small, far away from each other, and mostly made of ice and light elements you won't find enough building materials there to sustain a civilization, nor much nuclear fuel (even fusion reactors don't just need hydrogen, that's the fuel, but the building is made of other materials, some of them will need regular replacing). It doesn't really make any sense to ever (regardless of tech level) go live much further than Jupiter, Saturn at most, unless you're going to a different star altogether. If lack of space is the issue than it would make more sense to build space habitats and park them in the inner solar system than to send them all the way to the Oort Cloud.
@@edmondantes4338 I imagine that the Oort cloud could be home to a mining colony. Lots of water rich comets in the Oort cloud. Maybe one day we'll expand so far that mining the Oort cloud will be economic.
@@960456 Water is not a rare molecule in the universe or the Solar System. Not only is Earth full of water, there's also water on Mars and the Moon, on Ceres, on the moons of Jupiter, Saturn, and those of the ice giants, plus ice comets reach the inner solar system all the time. No need to go as far as the Oort Cloud to find water.
Many red dwarves end up being flare stars. Maybe it's just short man syndrome. Life is far more likely around orange or yellow dwarves. Still small-ish stars but much bigger than red dwarves, a much more stable energy output, flares are much less common, and the goldilocks zone is far enough away as to not tidally lock potentially habitable planets. Case in point, our sun is a yellow dwarf, and it's done alright by us.
What people fail to realize is our sun is a dwarf star, but the extent of it's gravitational influence, on its celestial neighbors, is staggering, by human perspective. So, imagining a more massive star having a much larger influence, isn't out of the question.
If candidate 1 exists it could have habitable moons if you think of the way planetary evolution and migration works. If the planet formed further out, which it probably did, the moons could be icy and therefore have oceans and an atmosphere being that close to the star.
A lot of fictional planets are in this system, primarily around Alpha Centauri A and Proxima Centauri B. Because Alpha Centauri B has been “forgotten” I think the fictional planet I conceptualized named Embrace gives it some well needed love.
Since learning of solar lensing telescopes I doubt know why we aren’t rushing to build one it solves like the most powerful tool we could have for exoplanets
we are trying to build one, the concept for it is getting nasa funding the problem is we don’t have a rocket powerful enough to get it that far away in any reasonable amount of time (less than 20 years, right now it’ll take i think around 30 or more)
I was hoping, in this grand tour, that you would have had an animation depicting the system as a whole. I wanted to see how the three stars orbit around each other and how the known and probable planets around each move, all at scale.
you wouldn’t be able to see anything interesting unfortunately if you wanted to get the whole system in a single frame to scale Alpha Centauri A and B would just look like a single point of light and you wouldn’t be able to see proxima centauri the system is incredibly spread out

I'm always amazed with what's out there, but, talk about we could travel there one day or send probes there will just never happen, distances are just too great. As you said, the best way to explore these worlds is by telescopes and the way this tech is improving. In 50 years time, just can't imagine what they will be capable of, look at JWST. This will be the best way to discover new planets, because we will never travel there unfortunately.
@@4yerears I agree, "never" is a big statement, but with the distances in the universe and you or anything with mass, can't go any faster than the speed of light, well, can't even reach the speed of light. Ok. some people say, well a very intelligent civilization may develop this tech, no, it will never happen. Also, if you could travel at the speed of light, it would still take 1000's of years to even travel a small area of our galaxy. So I will stick with the never.
@renegade040, true, i also think faster than light is impossible but, there are concepts for technology that exist today and are possible under known science that could get us to 50% lightspeed. That puts travel times to Alpha Centauri within 8 years, well within a human lifetime. That puts dozens of stars within reach, so even if people won’t make it across the galaxy in one lifetime well still get to places like Alpha Cen, Sirius, Tau Ceti, Procyon, etc
@@Kyplanet893 Agree, even 50% of light speed is crazy fast and it may happen in the distant future. Their is another article I did read, can't find it now and their is more problems that need to be overcome which will be extremely difficult. It did say to travel at these speeds, it's not just about the speed.You can't just hit the go button, to accelerate to a speed of 50% of light in a few days, it must be done over a length of time, say 3 to 4 months, because any quicker the G-forces would be to great. Even take this time the G-force are around 8 G's. Now a human body could not tolerate this for too long. So, I would think it would take well over 1 year to 2 years just to get that speed, then would need the same time to slow down, so would need at least 12 years to get to Alpha Centauri, just not feasible, but would be great to see happen, but not in my life time, not even close.
TOLIMAN telescope stands for Telescope for Orbit Locus Interferometric Monitoring of our Astronomical Neighborhood it’s launch date is no earlier than late 2024, i haven’t heard much else besides that
Important: the planets are not photos. Just artwork of how we imagine the planets are looking like. The name Proxima is most likely because of proximity. The closest star. Will probably take 10s or 100s of years to be sure if we've discovered all Alpha Centauri planets. We can discover planets if the planets are between us and the star. So it will take many more years.. excited!!!
2:10 into the video he said 'proxima D is about 1/4 the size of earth or 3 times bigger than mars' this is the point i closed the video since its complete nonsense
i was talking about mass, not radius mars is 0.1 earth masses, proxima d is about 0.25 if i’m talking about radius i’ll say “in radius” my default is always mass, it’s just a subconscious habit
Space Engine gives an extremely optimistic rendition of Prox b... I'd expect a grey ball; much more interested in the possibility of small planets or moons around the golden and silver suns. The day/night cycle alone could be crazy. Depending on what day of the solar and co-orbital year it is, you can have some periods with no actual night, just half-night when the further sun is the only thing lighting up the sky. If by some miracle there was a technological civilization right there, Prox b would prove a tantalizing target for their near-term spaceflight.
proxima cen is right where an oort cloud should be so there might not be one plus circumbinary orbits are pretty unstable here there definitely could be dwarf planets but they’ll probably be more like ceres orbit wise, not pluto and eris and haumea and all the kuiper belt ones though proxima centauri could actually host a kuiper belt analogue so there’s a lot more chances there
@@Kyplanet893 in it's interior since it's 6-8 Earth masses it's energy supply is far greater than earths I highly dought it's mass is enough to be a mini-neptune. It could as well be a hycean planet
pretty much everything up to the hubble limit isn’t too far (aka, an unimaginably large region of space is currently "not too far") it just depends how much effort you want to give
@@_apsis We could get humans there, but they would be cut off from the rest of humanity, it would take four years to send a message, and another four to receive one back.
@@griffenbaum yes, it would. that certainly doesn’t mean it’s "too far" you also don’t need to start your colonization with a manned ship, you can send several unmanned vehicles to prepare the location before people are sent there
you can terraform any planet you want with enough brute force though im personally against terraforming in general because better options for creating living area exist
@@Kyplanet893, you are wrong. The issues with space habitats are worse. We cannot protect a population over long time frames from cosmic radiation, which means space platforms are of limited use. We have all the water we need to terraform both Mars and Venus in the Oort Cloud and use Luna as a resource extraction centre
I am not saying they are perfect wrong gravity and such but you would need something planet-sized in the first place, and Mars and Venus are planet-sized in the first place
i’ve heard all the arguments against space habitats, i still think they’re better than terraforming the radiation problem is solvable, just like with terraforming, but at this point i’ve debated it so many times i really don’t want to do it again lol so let’s just agree to disagree (except for the part about using the moon to extract resources, i 100% agree with that, i am very pro lunar colonization)
@@Kyplanet893@Kyplanet893 The radiation problem with smaller habitats is not solvable over very long periods, so we need better material science, and we are not getting there. For space platforms to work, you would have to build something like a Bishop Ring and use costly and complex materials, which we have been unable to develop. When I was at Manchester University, it was agreed habitats would likely be O'Neill cylinders. They are used for fairly short-term habitats like off-world industries, terraforming of planets and space arks for up to a century or two inside an asteroid, so they are closer to oil rigs than cities (who want to live in an oil rig). We are closer to developing Von Neumann and relativity space flight than the technology then that we need for space habitats. As technology improves, Mars and Venus can be terraformed in a couple of centuries, and mostly, it could be automated given you would not want to be on the surface of Mars or Venus during the process. Something like super large habitats would take longer; planets are just easier to develop long-term. That does not include the issues of orbital dynamics, which also limit the size of such structures as a total dead-end.
What if Alpha Centauri A & B "caught" a dwarf planet in their habitatal zone? Are they still vulnerable to flares or not as much? Would they be blasted by radiation because of two suns or would their combined heart output create a habitual zone far enough away? I guess I'm just wondering because (this isn't your fault) there isn't a "simple diagram" showing the probable orbiting patterns of each star and their planets I can find
Very thoughtful narrative. I especially appreciate your clarification at the beginning of the video that the watcher should be aware of this info becoming dated. That sort of thing is an important and often forgotten detail. Science moves fast and failure to acknowledge this is very easy for a lot of enthusiasts.
I wonder what kind of life would be in this system. Maybe a mix of carbon around the poles of Prox B and some of the harsher ones could be good with silicon life if they have geological activity going on.
i always feel like going monkey mode at the thought that with all of the possibilities of everything we happen to be exactly when working a 9-5 to death for no reward is just the basis of life
Since Proxima Centauri is less gravitationally-bound to it's system and it will eventually be much closer to our solar system then wouldn't that mean theoretically the sun COULD capture Proxima Centauri? If so that would probably be pretty cool.
even at its closest approach it’ll still be closer to alpha cen than the solar system, and alpha centauri A and B are about 2x more massive than the Sun combined so unless something really weird happens and something disturbs the system we wont capture proxima centauri
@@Kyplanet893 Ah alright, Though since the two binary Alpha Centauri stars are twice the mass of the sun do you think it would be possible for alpha Centauri to capture the sun?
I am very glad you uploaded this. Here's a comment I've been wanting to leave but couldn't think of the right video to leave it on (pardon the schizo ranting): It fucks me up that the Alpha Centauri system is so close that it can be considered to be actually physically *there*, unlike most other star systems. Like if a day comes when we can reliably send sophisticated probes and large numbers of astronauts as far as Pluto, Alpha Centauri does not feel like it's much further to go (yeah I know Alpha Centauri is several thousand times further than Pluto), in principle, a mission to Alpha Centauri could almost be handled similarly to a mission to Pluto, only way way longer, and without any existing infrastructure at the destination, and it's almost definitely a one-way trip. Keep in mind I did preface this with "pardon the schizo ranting."
yeah the planets do deserve names but idk what we’d name them it’s the most important system outside of our own, you really cant do the same thing as other exoplanets that have gotten official names (like name Proxima b after the Mongolian word for “bear cub” which is what the exoplanet Bambaruush was named after) we have to figure something out that represents all of humanity
It takes 50,000 years to reach even the outer boundaries of the proxima system with our current technology- the fastest spacecraft reaching 650,000 km/h
@@jackturner8472 at 20% the speed of light it would still take over 20 years to reach the system. Which isn’t a bad time frame at all. But who’s to say these tiny probes even make the journey?
problem is none of the planets transit their stars so jwst would have a pretty hard time finding any atmospheres and such if we pushed it to its absolute limits it may see something but it wouldn’t be much
@@Kyplanet893 I'm somewhat confused (this is coming from someone who has no indepth knowledge of astronomy) if they orbit their star shouldn't they transit (as in pass by it in the direction of our telescopes) sometimes?

So, I would think it would take well over 1 year to 2 years just to get that speed, then would need the same time to slow down, so would need at least 12 years to get to Alpha Centauri, just not feasible, but would be great to see happen, but not in my life time, not even close.
I can't find any reference to the telescope you mention isn't launching soon. Could you spell the name?
TOLIMAN telescope
stands for Telescope for Orbit Locus Interferometric Monitoring of our Astronomical Neighborhood
it’s launch date is no earlier than late 2024, i haven’t heard much else besides that
I'm here in April 2063! Warp drive has just been invented. We'll be there in a couple of years!
Warp drive ship is not enough, please develop some beam ships and tachyonic sliptime ships if you wanna back to 2024.
What about Alpha Centauri Bc?
there isn’t much evidence for it, and it probably doesn’t exist
Ok
great
what is the official names or when there will be official names for the planets
there aren’t any official names for them yet, but 160+ exoplanets do have them already
ok thanks
Important: the planets are not photos. Just artwork of how we imagine the planets are looking like.
The name Proxima is most likely because of proximity. The closest star.
Will probably take 10s or 100s of years to be sure if we've discovered all Alpha Centauri planets. We can discover planets if the planets are between us and the star. So it will take many more years.. excited!!!
I now love the idea of giant lilipads on hycean planets, planted there via; panspermia
so if proxima centauri is a part of the system, does that mean that in a few hundred thousand years it will become the 3rd closest star to us?
2:10 into the video he said 'proxima D is about 1/4 the size of earth or 3 times bigger than mars' this is the point i closed the video since its complete nonsense
i was talking about mass, not radius
mars is 0.1 earth masses, proxima d is about 0.25
if i’m talking about radius i’ll say “in radius”
my default is always mass, it’s just a subconscious habit
@@Kyplanet893 i was just alittle confused because i know size and bigger are not he same as mass and density so the math wasn't adding up.
Some crazy homeless guy who was preaching about it brought me here..
6:03 Boys, James Cameron was right
Unobtanium here we come
Ikr. He written the script for the movie back in 90s to 2000s, and Candidate 1 was discovered back in 2021.
Space Engine gives an extremely optimistic rendition of Prox b... I'd expect a grey ball; much more interested in the possibility of small planets or moons around the golden and silver suns. The day/night cycle alone could be crazy. Depending on what day of the solar and co-orbital year it is, you can have some periods with no actual night, just half-night when the further sun is the only thing lighting up the sky. If by some miracle there was a technological civilization right there, Prox b would prove a tantalizing target for their near-term spaceflight.
There should be some dwarf planets in Centauri's version of an Oort cloud.
proxima cen is right where an oort cloud should be so there might not be one
plus circumbinary orbits are pretty unstable here
there definitely could be dwarf planets but they’ll probably be more like ceres orbit wise, not pluto and eris and haumea and all the kuiper belt ones
though proxima centauri could actually host a kuiper belt analogue so there’s a lot more chances there
Love the video
If proxima c has been confirmed to exist it's probably more likely to sustain life because of its huge size and not being this close to it's stars
it’s negative 389 degrees i don’t think it’s chances for life are very high lmao
and it’s still disputed
@@Kyplanet893 in it's interior since it's 6-8 Earth masses it's energy supply is far greater than earths I highly dought it's mass is enough to be a mini-neptune. It could as well be a hycean planet
@@Kyplanet893 but all of them are interesting
@@Kyplanet893 oh I forgot it's still disputed
@@saviourojukwu893 cold hycean planets my beloved
I wonder if we could make settlements on it, or if it would be too far
pretty much everything up to the hubble limit isn’t too far (aka, an unimaginably large region of space is currently "not too far")
it just depends how much effort you want to give
@@_apsis We could get humans there, but they would be cut off from the rest of humanity, it would take four years to send a message, and another four to receive one back.
@@griffenbaum that’s far from being cut off
@@_apsis yeah but if there is any type of emergency, it would take years for aid to arrive, the colony would have to be self sufficient from day one.
@@griffenbaum yes, it would. that certainly doesn’t mean it’s "too far"
you also don’t need to start your colonization with a manned ship, you can send several unmanned vehicles to prepare the location before people are sent there
Could we also use a solar gravitational lens to take high quality pictures of other stars?
For the algorithm!!! Brilliant video mate, looking forward to being apart of your UA-cam journey to much success. God bless!
This narration would benefit from a graphic which maps the orbits of these bodies.

Could you terraform the planets around Alpha Centauri?
you can terraform any planet you want with enough brute force
though im personally against terraforming in general because better options for creating living area exist
@@Kyplanet893, you are wrong. The issues with space habitats are worse. We cannot protect a population over long time frames from cosmic radiation, which means space platforms are of limited use. We have all the water we need to terraform both Mars and Venus in the Oort Cloud and use Luna as a resource extraction centre
I am not saying they are perfect wrong gravity and such but you would need something planet-sized in the first place, and Mars and Venus are planet-sized in the first place
i’ve heard all the arguments against space habitats, i still think they’re better than terraforming
the radiation problem is solvable, just like with terraforming, but at this point i’ve debated it so many times i really don’t want to do it again lol
so let’s just agree to disagree
(except for the part about using the moon to extract resources, i 100% agree with that, i am very pro lunar colonization)
@@Kyplanet893@Kyplanet893 The radiation problem with smaller habitats is not solvable over very long periods, so we need better material science, and we are not getting there. For space platforms to work, you would have to build something like a Bishop Ring and use costly and complex materials, which we have been unable to develop. When I was at Manchester University, it was agreed habitats would likely be O'Neill cylinders. They are used for fairly short-term habitats like off-world industries, terraforming of planets and space arks for up to a century or two inside an asteroid, so they are closer to oil rigs than cities (who want to live in an oil rig). We are closer to developing Von Neumann and relativity space flight than the technology then that we need for space habitats. As technology improves, Mars and Venus can be terraformed in a couple of centuries, and mostly, it could be automated given you would not want to be on the surface of Mars or Venus during the process. Something like super large habitats would take longer; planets are just easier to develop long-term. That does not include the issues of orbital dynamics, which also limit the size of such structures as a total dead-end.
I like that i can go there in games like starfield
5:00 -- God must REALLY like Proxima c to put that size of a ring on it!
very good video
Three Body Problem reference
Space engine looks great. Cool topic, good video 👍
What if Alpha Centauri A & B "caught" a dwarf planet in their habitatal zone?
Are they still vulnerable to flares or not as much? Would they be blasted by radiation because of two suns or would their combined heart output create a habitual zone far enough away?
I guess I'm just wondering because (this isn't your fault) there isn't a "simple diagram" showing the probable orbiting patterns of each star and their planets I can find
Very thoughtful narrative. I especially appreciate your clarification at the beginning of the video that the watcher should be aware of this info becoming dated. That sort of thing is an important and often forgotten detail. Science moves fast and failure to acknowledge this is very easy for a lot of enthusiasts.
Which one does Zefram Cochrane come from?
Never realized Alpha Centauri was Trisolaris.
What do you think about Zeta Reticuli system? Maybe you'll rank some yellow dwarf systems? That would be interesting.
I wonder what kind of life would be in this system. Maybe a mix of carbon around the poles of Prox B and some of the harsher ones could be good with silicon life if they have geological activity going on.
Imagine we discover literal pandora around candidate 1
candidate 1 is eerily similar to the gas giant pandora orbits around

i always feel like going monkey mode at the thought that with all of the possibilities of everything we happen to be exactly when working a 9-5 to death for no reward is just the basis of life
Why did they skip Proxima a when naming worlds?
Proxima A is technically Proxima Centauri itself
Since Proxima Centauri is less gravitationally-bound to it's system and it will eventually be much closer to our solar system then wouldn't that mean theoretically the sun COULD capture Proxima Centauri? If so that would probably be pretty cool.
even at its closest approach it’ll still be closer to alpha cen than the solar system, and alpha centauri A and B are about 2x more massive than the Sun combined so unless something really weird happens and something disturbs the system we wont capture proxima centauri
@@Kyplanet893 Ah alright, Though since the two binary Alpha Centauri stars are twice the mass of the sun do you think it would be possible for alpha Centauri to capture the sun?
no, theyll be moving too fast, and will still be over 2 light years apart
@@Kyplanet893 Alright, though I think it would be cool if there was a book/tv series based off of that concept.
No planet called Chiron?
In this house we call Chiron, Planet.
I am very glad you uploaded this. Here's a comment I've been wanting to leave but couldn't think of the right video to leave it on (pardon the schizo ranting):
It fucks me up that the Alpha Centauri system is so close that it can be considered to be actually physically *there*, unlike most other star systems. Like if a day comes when we can reliably send sophisticated probes and large numbers of astronauts as far as Pluto, Alpha Centauri does not feel like it's much further to go (yeah I know Alpha Centauri is several thousand times further than Pluto), in principle, a mission to Alpha Centauri could almost be handled similarly to a mission to Pluto, only way way longer, and without any existing infrastructure at the destination, and it's almost definitely a one-way trip.
Keep in mind I did preface this with "pardon the schizo ranting."
At the very least, it's close enough that all confirmed planets in it deserve true names :)
yeah the planets do deserve names but idk what we’d name them
it’s the most important system outside of our own, you really cant do the same thing as other exoplanets that have gotten official names (like name Proxima b after the Mongolian word for “bear cub” which is what the exoplanet Bambaruush was named after)
we have to figure something out that represents all of humanity
It'll take 40000 years to reach there with the fastest probe
We could of with that interstellar pogo stick ship the Orion Project
real life Trisolar 😱😱😱😱😱
Last century NASA sent probes to all our planets.
I wish orgs would start working on sending atleast 1 probe to our nearest star system.
there are people working on it, it’s just very, very hard
It takes 50,000 years to reach even the outer boundaries of the proxima system with our current technology- the fastest spacecraft reaching 650,000 km/h
@@ry_an.you mean with current launched probes? Breakthrough Starshot is entirely possible right now, the infrastructure just isn’t built yet.
@@jackturner8472 at 20% the speed of light it would still take over 20 years to reach the system. Which isn’t a bad time frame at all. But who’s to say these tiny probes even make the journey?
Why wouldn't they? Voyager 1 stills dings us how many decades later?@@ry_an.
wow candidate 1 is SUCH a "creative" name
Temperatures in °C, please.
Good tv
We gotta turn the James Webb on this system ASAP
problem is none of the planets transit their stars so jwst would have a pretty hard time finding any atmospheres and such
if we pushed it to its absolute limits it may see something but it wouldn’t be much
@@Kyplanet893 I'm somewhat confused (this is coming from someone who has no indepth knowledge of astronomy) if they orbit their star shouldn't they transit (as in pass by it in the direction of our telescopes) sometimes?
@@edwardwindsor2516 we’re at the wrong angle to see the transits
it’s the difference between viewing an orbit edge-on, where you would see the transit, and from the top down, where you wouldn’t
