    Hi can you explain little bit more

  2. Chaitu Lion

    No it’s not possible it’s against nature rules

  3. Robert Dobson

    Venus is dead scary harry except and move on

  4. Yuggdrasial

    Neither white dwarfs nor neutron stars are stars as neither contain active nuclear fusion.

  5. Declan White

    i don’t know…how can a planet be bigger than its arse

  6. Rehan Sheikh

    Thanks ☺️

  7. Paul Galaxy

    Amazing 👌

  8. MaryLu Harmon

    Awesome video! Thank you!

    You, uh, didn’t give a very good explanation of a brown dwarf’s mass. A brown dwarf is between 13 Jupiters and 0.08 Suns, sure, but that’s totally meaningless without knowing how many Jupiters make up a Sun. (0.08 solar masses is about 83 Jupiters, according to Google).

    Can a HUMAN bigger than its star 💫?

  12. Christmas Snow

    How massive can a terrestrial planet get?

  13. Science Troll

    More to the point, can a planet be massive enough and it’s star of small enough mass that the star orbits it’s planet ? Virtual cake for the coolest suggested nomenclature.

  14. TheElectricOrigins

    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?

    And the take away…..
    Red, white and brown Dwarf lives matter too.

  17. IMustBe Crazy

    Not according to Universe Sandbox.

  18. Darth Rageous

    So…the radius/circumfrence of the planet can be larger than the host star…but NEVER larger in mass than its host star🤔


    Positive reinforcement 🤔

  20. Bull Shyte

    A planet bigger than the star its orbiting ?
    Wouldn’t the star be orbiting the planet ?
    unbelievable ……………..

  21. kirby march barcena

    A planet bigger than its Sun? Thats possible. I think this will happen after our own Sun finished its red giant phase and becomes smaller than Jupiter.

  22. Lunamaria

    Before I unpause and actually start the video i’d like to answer the title question.. We already have proof of planets orbiting neutron stars, and white dwarf stars, and they are only about 25 miles in diameter.. The title doesn’t specify at what face of a star’s life lol

  23. White Falcon

    Dont say First

  24. MichaelRacelli

    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.

  25. Kees water

    Because Lord God made it so, so easy to question this.
    Second, the Sun is NOT a star according to the Bible its a source of light.

    I hope you know you can turn off lens flares and change a lot of settings in space engine

  28. henry gillenardo

    Are you going to make a video about phosphine on Venus?

  29. Jose rafael Alvarez

    What the narrator say *star* what I listen *staa* omg

  30. X Archive

    Hi Sir, Great Video as always.
    Could you please make one about the latest Venus-Phosphine Descovery?

  31. Bryon Feliksa

    Is this an old video you reposted? I swear I’ve seen this :)

  32. Lilee

    Watching again for the new information! :)

  33. BoSS

  34. MMO Archives

    that’s no planet, that’s a failed star

  35. AlmostEthical

    It’s said that Jupiter had once migrated to the inner solar system because the amount of material slewed off by the Sun slowed its orbit. This may have also happened with planet WD1856b when its orbit passed through material cast off by the star at the end of its red giant phase.

    Jupiter was prevented from moving too far into the inner system by the tug of Saturn, but WD1856b might not have had another giant planet on the other side to prevent its inward spiral.

  36. Sterling Crockett

    It’s neat to find exoplanets around red dwarfs, but bigger or smaller, two problems always remain.
    1. It’s cold outside, there’s no kind of atmosphere, all alone, more or less,
    2. We want to fly far away from here, fun fun fun in the sun sun sun.
    3. They’re always full of smegheads, or “smeee heees” if one’s core programming can be partially overridden.

    Wait why.. is this a reupload?

  38. Hastati ™

    With billions and billions of stars out there anything is possible

  39. karl el

    Why are stars hosting these parties though?

  40. elvis star

    Amazing info!

  41. Joseph Fraser

    now this is a fun question

  42. Anotherordinaryguy 499

    There’s a gas giant orbiting around a white dwarf (star corpse) just recently discovered.

  43. Petra - wir uns kennenler

    0:42 cool

  44. Astrodex

    What a time to be alive!

  45. Jesus H Christ

    The simple answer is yes!

  46. harsha A

    Where do you get this amazing animations?

  47. nitramyar

    Thanks for the update, Alex!

  48. Meloveulongtime

    A planet could not be more massive than its star otherwise the planet would be the center of the solar system

  49. Kati OBrien

    Love learning from this channel.

  50. Reality Vanguard

    I bought my girlfriend your rose galaxy displate :) good stuff

  51. kurppakiivi


  52. wllot

    This stuff just makes you remember that our neither our planet nor our solar system is unique in any way, it’s just one of trillions that exist in the universe

  53. yetzt

    yes, if the star is a neutron star. ez physics clap, 5 second video.

  54. Distman

    I really like your VO, very fitting for space videos. <3

  55. Alan Kerlidou

    I haven’t watched the video. I am under-educated about the science of Astrology, but my guess is YES! As long as the planet has a mass lower than its sun, the planet can be bigger in Radius.
    Am right? See you back in 8:19mins

  56. Amethyst Z

    Thank you Astrum!!!! I love your content <3

  57. sandun thilina

    Its like having an engineering degree and still works as a labour

  58. Sanket Jain

    Wait is this a reupload? Bc i definitely remember another video on the same topic by astrum.. 🤨

  59. Loui Throttler

    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?

  60. ThisGalaxyCat

    I just love vast void of space its just fascinating also you can see my username 😂

  61. Particulator

    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.

  62. CrankyPants

    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.

  63. Pak Furious

    i wish we could go other stars and planets but here we are

  64. Vinci480

    What about Hot Jupiter/Saturns? Like the Puffy Planets. Aren’t they supposed to be larger in size by a long shot?

  65. Students for a Democratic

    I am disappointed. Brown Dwarfs, of course, do engage in nuclear fusion of tritium and lithium. In fact, the definition of brown dwarf includes this.

  66. Mike DeMarco

    Yes, if it’s less dense, and has less actual mass.

  67. samantha qiu

    bigger… yes

    more massive… most likely not

  68. Nils Rocholl

    Im just wondering, couldn’t be there life on brown dwarfs? I mean they could have an atmosphere and produce enough heat themselves to host life right?

  69. Trevor Jones

    This man’s videos are 1/2 extremely interesting, 1/2 extremely terrifying

  70. Spaceman Spiff

    I bet a huge planet mostly composed of iron could be larger than a small star composed of mostly hydrogen

  71. Isaac Pinkus

    one wonders what the dynamics of a system whose sun star is smaller than one of it’s planets would be like

  72. मयंक . Mayank

    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.

  73. Aayush Lamsal

    A question : Suppose space x successfully goes to Mars and colonize it. Will Elon Muslk known as god of Mars?
    Likewise is there any god for earth?


    Astrum is amazing them voice is so soothing along with the pictures and the learning. I hope you can get more subscribers😊

  75. Corona nate

    at 6:00, how did they determind the mass of that planet? gravitational lensing perhaps?

  76. Literatura BDSM

    I do love your videos, but the ammount of adds you put on them makes them unwatchable in anything that isn’t a computer. I get the revenue is needed, but it hurts your channel. I do not watch it if it isn’t in the computer. One or two small adds do not ruin the video….but more than that is not okay

  77. Brawler

    How can a planet be bigger than its star?
    Answer: Its most likely a failed star otherwise planets dont reach those masses.

  78. Agent X

    So many estimates and guessing I think future interstellar travlers will have much to discover and correct.

  79. Randy James

    I knew that there were stars with “Beta” in their name. Now I find out there’s (maybe) a “VHS” star?? Sweet!

  80. Alexis Collado

    That animation of the Hertzsprung Russell Diagram is so cool!!!

    Posting a comment for the algorithm boost as well

  82. Matt Taylor

    Unlike the avatar, when the world needed him most, astrum did not disappear and posted a new video

  83. Huawei is a criminal orga

    Alright, count black holes and neutron stars …

  84. John Marksman

    What i would like to know were Stars planets at one point in their lifetime or from nothing to Star

    I wish we could be out in the universe already. Among like 50 other planets

    “Big” does not mean ‘mass’ end of clip.

    I was like “wait a min…Mandela effect??”

  92. GamingWithNate

    I tend to like the videos before I watch them because I already know they’re going to be great.

    I do remember watching this, but will happily watch it again since I watched it a couple months ago or so

  97. Techie Science

    Oh Man bigger star Mystery needs to be solved👍👍

    🙌U have motivated ME & MOST to establish their youtube brand🙏😇

    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.

  99. Phas Low

    I can’t wait for your take on the Venus discovery!

    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!
