As someone who has no knowledge of astronomy and is thinking of it becoming a new hobby I found this video entertaining. I look forward to more videos like this.
Very good video! Tho I was expecting to know about their planets. After looking it up myself I found out Proxima Centauri has a planet in the habitable zone! As for feedback I found the text sound volume was kind of high
It does but proxima is a flar star it flared up a few years ago and was 75% brighter to where it could seen so any life if it had time to develop is now extinct
Proxima centauri is apart the alpha centauri system its the 3rd but smallest star in that system it's obit is a few light years but its still apart of that system
Procyon is not actually fusing helium yet. It will become a red giant first and then, at the top of the red giant branch, when the mass of its inert, electron-degenerate helium core reaches 0.47 Solar masses, finally ignite helium fusion it a violent flash (not visible from the surface of the star). The star will then contact again and fuse helium for about 100Myr.
Thanks ! It's always hard to judge how much info to put in a video. I don't want the video to be too long but I could have put the stars' ages in the text info that appears for each star.
Do we know their planets?? Yeah, we should definitely have visited them already wtheck, it’s been ages !!!!! Yes however, it would take 135 thousand years to reach Alpha Centauri traveling with 2 AU a year, unless using Delta V 25 km/s, which would give a speed of 175 km/s and we could reach Alpha Centauri in 7.700 years, we need to send Noah’s Ark eggs of all Earth’s creatures to there so that we can colonize it !!! You have a *REALLY* cool digital telescope 🔭!!!!! are you an astronomer??
Wonderfu;l information. Thank you. I just subscribed. Just one piece of advice. Unfortunately like me, you are not exactly a pleasentt looking guy, added to it the pimples, freckles and the unwashed oily skin and hair. You own face and body covers half the screen, instead of the star photos or simple formula and numbers. you should limit yourself to a standard corner inset, and that only after having viisted a dermatologist, a barber and have showered and scrubbed before filming. and of course, a shirt your own size rather than two sizes too small. Sorry for saying this, but it is for your own suvvess. (And may I ask what happened to Epsilon Indi and Tau Ceti?)
Alpha Centauri is 3.4 light years away from Earth, if used a fission-fueled rocket, oops!! You said 4 LY?? (I’ve got it that it’s 3.4 LY away). Delta V with a double exhaust speed would obtain 8% of the speed of light (300.000 km/s) - which means a one-way transit of 54 years to Alpha Centauri, to decelerate at the point of destination, the spacecraft would have to slow down to 4% c, and it would take 108 years. --> they should definitely send one on the way!!! There was a program of this purpose 1957-63 called “Orion” at the US Commission of Atomic Energy and came from Los Alamos, but the USA had to stop it due to the prohibition of putting “nuclear weapons” in space as written in the sleeping 1963 Outerspace Treaty and the forbearance of detonating nuclears in space (and producing them, I understand clean fusion D-He3, but not uranium and plutonium, those aren’t natural reactions, they don’t exist anywhere in the universe, they’re artificial). They could use salt-water rockers instead to reach Alpha Centauri in 215 years. Thermonuclear would be the BEST rocket propulsion for interstellar travel !!! It would take 43 years to reach to the closest star. I wish I could make a video about this, but I haven’t got the video visuals technology to make an interesting film about interstellar transit. Next episode should be - how to reach to those stars?? (and to consider “what for” (and for what budget/ and purpose, yes, it would be “cool” to have a spacecraft/lander in a different stellar system, not that Webb won’t show enough about that, but what would they do once there?? We do get to see exoplanets and it’s nice, Hubble, TESS, Spitzer, Kepler showed them sufficiently. I barely recognize the Harvard Classification (OBAFGKM), I’m not a fan of stars, I am just interested in effective propulsion and decarbonification of energy sources for Earth. The UK is a *LEADER* in fusion - does the public / state talk about it in your homeland?? You passed a legislation about installing fusion plants in your country this October 2021, are they doing it??
Respectfully, I think you got 3.4LY confused with 4.3LY. Proxima Centauri is the nearest of the 3 stars of that system. A physics professor once demonstrated the impossibility of traveling to the stars. He was right, of course, given our current tech. A leisurely trip is required for soft cargo like humans, but durable cargo like hardened machines could be accelerated about the Moon (in the future) in a frictionless vacuum chamber until released, already going as fast as they will, some percentage of the speed of light.)
@@thomasaquinas2600 4% of that speed (of c) if someone used a fission propulsion, but no one wants to put nuclears even in space (uranium-235 and plutonium -239, thorium), a fusion rocket COULD travel to a star ⭐️ - question is: do we NEED that?? For the “fun” of it/ for exploration / for curiosity ?? It is sufficiently important to find yourself on Mars already which is long overdue - however going to the stars?! Not that anything not to mention anyone soft cargo could actually land in there if it is just another plasma giant sphere of ultra hot gases i.e. plasma it’s not a solid - you can see in the those objects from the solar system what for going there - they will go there definitely in the future but right now Earth has to overcome the pandemic not play in space. Do you see the purpose in traveling to another natural fusion reactor i.e. a star 🌟???? Maybe someone would want to colonize another solar system with humanity with humankind that first they would have to get rid of non-democracy on this given a planet that they have.

Plz make a video on how to watch stars ? What all things can we make out in the night sky with naked eye and amateur telescope 🔭
Thanks for this great content
I'm glad you enjoyed it !
Just found your videos, great work!!
As someone who has no knowledge of astronomy and is thinking of it becoming a new hobby I found this video entertaining. I look forward to more videos like this.
Thanks !!
Great video sir. Really enjoyed it
Awesome Video. When I saw about Wolf 359 all I could think of was Starfleet’s defeat at the hands of the Borg in 2367.
Very good video! Tho I was expecting to know about their planets. After looking it up myself I found out Proxima Centauri has a planet in the habitable zone!

Excellent video, thanks!
Glad you liked it!
Informative video and lovely watching it. Would love for you to make a video that talks about black holes and light speed.
There are also sometimes “double stars”, binary star systems
I'm so happy youtube recommended this video. Keep it up!
Thank you! Will do!
Proxima centauri is apart the alpha centauri system its the 3rd but smallest star in that system it's obit is a few light years but its still apart of that system
That was a great video. How about you finish up the dwarfs
Great video !
Thank you
What a excellent video. Really enjoyed it. 👍🏻
Many thanks!
That was way Kool !
proxima centauri actually has a 3rd planet orbiting in 5 days and pretty much earth like... was discovered recently
Proxima centauri is a flare star though even with planets life can't exist
Thanks
Great entertaining content.
Glad you enjoyed it
Loved it.
Thank u very much .Beautifully u explain these fact .
Thanks and welcome
You may want to mention that Proxima Centauri orbits Alpha / Beta Centauri.
I notice that most of the closest stars are red dwarf,interesting.
" the sun is about 1 solar mass"
Procyon is not actually fusing helium yet. It will become a red giant first and then, at the top of the red giant branch, when the mass of its inert, electron-degenerate helium core reaches 0.47 Solar masses, finally ignite helium fusion it a violent flash (not visible from the surface of the star). The star will then contact again and fuse helium for about 100Myr.
Oops, I always worry when I upload a video that there'll be mistakes in it.
That's normal, no worries :D I thought it was a nice video!
1:51 . . . Well ProxC has an Exoplanet within its Habital Zone !
Would make a great place to migrate Earth's life to in far future ?
Great vid. New sub. I'd recommend giving the star type when referencing them (O, B, A, F, G, K, and M).
Thanks for the sub!
Great video! Thank you! It would’ve been cool if you included how old they are but I’m grateful to have learned all the info you did share!
Thanks ! It's always hard to judge how much info to put in a video. I don't want the video to be too long but I could have put the stars' ages in the text info that appears for each star.
So, we are ignoring that Sirius has a white dwarf companion?
Whoops, left that one out !
@@skybugvideos It is pretty small.
good video
Do we know their planets?? Yeah, we should definitely have visited them already wtheck, it’s been ages !!!!!
Yes however, it would take 135 thousand years to reach Alpha Centauri traveling with 2 AU a year, unless using Delta V 25 km/s, which would give a speed of 175 km/s and we could reach Alpha Centauri in 7.700 years, we need to send Noah’s Ark eggs of all Earth’s creatures to there so that we can colonize it !!!
You have a *REALLY* cool digital telescope 🔭!!!!! are you an astronomer??
How come Tau Ceti didn't make the list?
It's just a bit too far away. If my list had been one star longer, it would have been Tau Ceti. Just a fraction further away than Procyon !
You cannot be Sirius ?
