The Planets That Can Dwarf Stars | Size Comparison
Вставка
- Опубліковано 7 сер 2024
- What makes a planet a planet? And what makes a star a star? Once we know this these defining characteristics, we start to notice that these definitions can overlap. Which begs the question, can a planet be bigger than its parent star?

Hi subscribers! This is a reupload of a video I released earlier this year which I had been meaning to reupload for a while. As it happened, there was some new and exciting relevant information released just yesterday from NASA about WD 1856 b which I have now included in the video. The old version had a pretty major mistake in it, where I said a neutron star is 10-29 solar masses, which is actually the mass range of the stars neutron stars originate from, so that has also been corrected. I will soon unlist the old version. Enjoy if you have never seen this before!
Nice
Hello! I'm a fan of your channel. Astronomy is my first love. Thanks for these videos!
Thanks for the information. I saw the tweet yesterday and at first glance mistook the bigger to be a dwarf star...but soon realized the smaller sphere was the star.
I noticed the mistake back when I first watched the video but I got what you were trying to say. Kudos for re-uploading it :)
Ah...that's why the title felt familiar. Glad to have a reason for rewatching. Thanks :)

We have all heard the factoid that if you were to put a neutron star next to the Earth, its magnetic field would draw the iron straight out of your blood.
I say that if you were to put a neutron star next to the Earth, then having all the iron removed from your blood would be the least of your problems.
I wonder about the iron leaching. If that were the case, then it would siphon iron from all sources, including planetary iron cores, asteroids, meteors, etc. Hmmm.
Blanca Camacho-Bonet yeah, iron in our blood is not magnetic afaik
@@Sadowsky46 what's afaik?
@@biancabonet acronym for "as far as i know"
@other account, did you know that our sun is a yellow dwarf star? It is actually white however our atmosphere is the main contributing factor in making it appear as though it is in fact yellow! Isn't that cool!?
Planet: "Look at me, I am the star now".
Lmao
Lmao
Can a planet be considered bigger than it's star if it gets more Likes, Followers and/or Subscribers.
Haha cute
I read this hearing the voice of Mr. Meeseeks. 😬
If you think about it, there are plenty of astronomical bodies just floating out there in the unerverse that are not stars. The only reason we have not been able to find any of these bodies, is because the do not admit light. That makes searching for then 10000x harder
Rouge planets
And moons
And black holes that have no accretion disk
And intergalactic or interstellar dust
Just here to boost the algorithm
This is the featured comment. Algorithm’s working great!
"Boost the algorithm" will soon become some sex related entry in urban dictionary.
Thx, just learned a new word lol 😄
For the algoritm. Let this channel go up and amongst the stars.
Did you know that our sun is a yellow dwarf star? Its actually white however our atmosphere is the main contributing factor in making it appear yellow to us!
4:38 the transition to the HR diagram is sick
How big can planets grow?
*talks about stars for 7minutes long*
But you know that it's basically the size of the celestial body that determines if it's one or the other, right?
@@educostanzo you mean the mass
Yeah wtf. Title should be different.
@@chomes8048 No it shouldn't.
Yep. I wanted to know more about these planets.
I can't wait for your take on the Venus discovery!
I was gonna ask about this lol
me too
Phas Low What?
What are you talking about? Have someone Finally Discovered where the Venus Planet is.
Or
My comment could go vou!
ARE YOU STUPID OR SOMETHING, THE PLANET CALLED “VENUS” HAS BEN DISCOVERED
FOR Many years
I r
@@duckduckandeby405 phosphine was discovered at concentrations larger than what can be produced naturally
@@duckduckandeby405 So much effort for such a stupid and incoherent comment
That was very well done, as always. Thanks for going back and fixing the first version of this. It says a lot that you care enough to do that.
I tend to like the videos before I watch them because I already know they're going to be great.
That's how I marry people
@@cesarcueto1995 touché.
likewise
That animation of the Hertzsprung Russell Diagram is so cool!!!
Yea
Thanks for telling me what it's called.
What I'm trying to figure out is if it's just purely pictorial, or if the real position of stars in space actually manifest into that diagram. Like a 'projection' for lack of the right term, probably. If so then that's so cool! I absolutely loved physics of stars and galaxies as part of studying physics but never saw the H-R diagram like that before.
i just wanted to say how much i enjoy your videos. when i really started becoming interested in space, i was also just beginning to use youtube. your channel was the first one i really started following - this was back in 2015. i love how you post so often now and continue to wow me with your ability to explain the subject matter in such an interesting way with beautiful pictures and production. i have learned so much! thanks again :)
Dropping by to say Hi to my Astro partner.
Hi Astrum !
This is hands-down one of my favorite channels... really exceptional content. It always make me laugh because the narrator's (Alex's) manner of speaking reminds me of Jemaine Clement playing the crab in the movie Moana. I always get a chuckle out of the image of the crab from Moana narrating these videos. Just a funny mental image though, all the love for Alex and this channel!
Fascinating stuff, I honestly regret not pursuing Astronomy .... love this stuff
Very nice Alex. Amazing video. 👍👍💙
What a interesting question to ponder upon. I've also wondered this sometimes.
Thanks for the explanation. I don't know it as a fact, but I can safely assume that the content has been gathered from various sources. It's quite comprehensive and thorough.
Love this channel! Love space talk, and your voice is so soothing. Good morning everyone have a blessed Sunday and a perfect start to a new week ❤️
Really love your videos, you do a fantastic job! Your narration is soothing and very professional, you should do voice overs or ASMR videos!
Astrum is amazing them voice is so soothing along with the pictures and the learning. I hope you can get more subscribers😊
I freakin love love love this channel!! Keep up the amazing work.
Short answer, there are known stars with a radius very near the radius of Jupiter. There are a number of exoplanets documented well enough have confidence they are 1.7x-3.0x the radius of Jupiter. There are also a number of stars believed to have radius smaller than Jupiter. So, while not 100% certain, there is strong evidence that the largest planets are larger than the smallest stars, including some red dwarf stars.
Yes, but the neat thing would be to find one of the largest planet with one of the smallest star in the same system and we haven't found that yet.
An other great vid from my favorite YT channel. It's never boring and always informative.
Because of Astrum I have learn about the star RS Puppis which to this day, still flabbergast me.
Beautiful as always.
Watching again for the new information! :)
I do remember watching this, but will happily watch it again since I watched it a couple months ago or so
Incredible content and research, what a time to be interested in astrophysics.
Thank you Astrum you’re doing very special work
I really like your VO, very fitting for space videos.
Love learning from this channel.
Thanks for the update, Alex!
I just made a video on what we mean by “bigger”. I appreciate you you explaining you mean volume, not mass. As volume is what our eyes can (but not alway) detect without measurements.
To be honest, I zone out listening to you sometimes, just gazing at the cool pictures lol
Super astronomy fan here. Sooo appreciate your vidz. Great visual presentations. And I love the way Alex narrates. His voice and accent makes for a relaxing but enthusiastic way to learning. Can't imagine anyone better suited. My only suggestion is if you can indicate whether a video clip or photo being shown are actual ones as opposed to simulations. Thank you very much!
Watched most of this video with my mouth hanging open...! Top job as always.
2:12 Whoa, that neutron star is directly above me and now I'm dead! (I'm from SF) 😂
Excellent video! Thanks for sharing.
Collaboration video with the host of the channel V101 science would be amazing. I would love to see what the two of you could come up with together. You both do awesome space content with awesome animations with both cool narration voices. I'm willing to bet that you guys could come up with some Discovery Channel stuff.
Question: I recall planets above Jupiters mass tend to barely increase in size anymore, as they become more massive. The ‚puffy‘ planets, afaik, are swollen up from heat, due to close proximity to a powerful star.
Soo
, can such large planets actually exist in a puny brown dwarfs system?
Your videos are so informative and interesting especially for astronomy buff like me. Keep moving forward. I'm sure you will hit a million subscribers mark soon. 😊
small star: You all will be wiff me forever?
bigger planets: you're darn right little guy
Love your videos, man!
fuckinell i can HEAR the smile and joy in your voice in every video and its uplifting as well as interesting, many thanks sir :)

Cool, never thought about neutron stars being smaller that their planets.
Apparently, even blackholes can have planets in stable orbits from a certain distance.
All the planets which are orbiting a black hole are Rogue planets
@@shreeanshushahakar5903 Far enough from event horizon can exist stable orbits.
@@shreeanshushahakar5903 How did you figure this? Because I'd say, if the original star's core was massive enough, and it just collapsed in without a supernova (this only happens on the higher mass end, supernovae are usually the prelude to smaller black holes or neutron stars), then its more distant planets could survive.
Saying "black holes only have rogue planets" is probably a statement you should back up with evidence.
@@vladskiobi I have evidence regarding this. In Dreksler Astral's video of Landing On Rogue Planets it is said that rogue Planets are Planets that orbit black holes.
I really enjoy your content Astrum
Amazing info!
Thanks for flashbanging me like 6 times in 8 minutes
Bigger? What is the size of a Star? Are brown dwarves Stars? And Sub Brown? And how do you classify Puffy Planets? Does the real size of a star include its photosphere, or the corona? How can we be sure of what we are observing?
Awesome video! Thank you!
“This makes them quite dim stars, and they only get dimmer over time”
Same
Another great video !
Hi Sir, Great Video as always.
Could you please make one about the latest Venus-Phosphine Descovery?
Always interesting, thank you.
Excellent video
Just so you know, the app he was using to simulate the different situations was universe sandbox 2.
Space Engine for the cinematics
Love this channel
I knew that there were stars with "Beta" in their name. Now I find out there's (maybe) a "VHS" star?? Sweet!
Those stars with beta in its name are Bayer designations
Sweet. Cool stuff Alex.
I'd like to see a video done about what you project the James Webb telescope to be capable of. If we throw its view on any of these systems you just mentioned could you make a projection graphic of what we'd most likely see for example?
This channel rocks 👌🏻
Great video
Thx my bro
👍🏻
Once again good video.
Love to watch ur videos
Hello I'm actually early this came out 5 minutes ago!
At first I was like,"a planet bigger that its star?" After I watched though, I was like "Oh, duh" lololol
(About 4:00) We've detected a nearby system, to WD-1856. It's full of hydrocarbons, but seems to almost repel water ice objects. It's system WD-40.
According to Leak Project (aka Rex Bear), he did a video about Planets turning into Stars (which is interesting).
If we move from 3D to 5D, then that dimension change could quite possibly make that a reality.
I was like “wait a min...Mandela effect??”
I saw this video before, like half a year ago, so I was like whaaaat? 2 hours ago??
I from Mars but don't tell anyone!
I get those all the time 😅
@@Hubcapdiamondstarhalo hello fellow alien i am a traveler from the planet pluto, i apologize for destroying your civilization
Oh Man bigger star Mystery needs to be solved👍👍
🙌U have motivated ME & MOST to establish their youtube brand🙏😇
You should play "Weyoun" the character from Deep Space Nine, you've got the voice
Love this
Very beautiful
These videos are really hard to watch on my phone in a dark room at night
Thank you 😊
Amazing
Jupiter: Wait, I'm smol now?
Universe: Always have been.
Amazing 👌
A correction, Brown Stars do indeed fusion hydrogen at their cores but only deuterium+deuterium or deuterium+protium starting reaction, meaning that the fusible material is usually below 1 % of their mass and the fusion happens very low ratio. if not type of fusion is possible, then it is considered a giant planet.
Where do you get this amazing animations?
Mind blowing.
I bought my girlfriend your rose galaxy displate :) good stuff
Love the 1440p60fps uploads 🍻
@astrum, at 2:40 "the detection method could define the mass only, not their radius" do you mean the radii of the exoplanets only? Or that of their host neutron star as well?
I’m here because I want to learn…
… and to boost the UA-cam algorithm of this video 🤓😁
Nice!!!! 🔥
Try disabling temperature if you are using Universe Sandbox 2... will prevent planets from getting blue
anyway love your videos
Thank you
could the gas planet have formed from the star's dust somehow?
The universe is not only stranger than we imagine, it is stranger than we _can_ imagine.
at 6:00, how did they determind the mass of that planet? gravitational lensing perhaps?
Makes me wonder if planets can be pushed by the red giant phase. So cool
Thanks ☺️

Ok this video was informative but was useless in answering the title, almost clickbaity...
Thumbnail: BIG PLANETS!!
Content: small stars
This may be an idiotic question but theoretically can a planet be so massive that it changes which orbits which? Like reverse the typical planets orbiting a star to a star orbiting a planet? Or is that simply not possible?
The cosmos is full of wonder. Questions that will never be answered and that’s good. Students aiming for their Doctorate, will have a myriad of questions to be answered and discovered.
Title: PLANETS!
Video: STARS!
Me: WHY AM I BEING BLINDED?!
So the star WD-1865B has been discovered. I wonder if star WD-40 is the location where the doctors found the "slightly greasy solar atoms" as described in the film the Fifth Element?
