One major difference is the i read that in a book

[UpcycleElectronics]

I still don't see how we can determine if an object was formed at the center of some material in a stellar nursery versus an object that has been ejected from another system. There are always going to be variations in elemental materials within a cloud of junk. The only time stuff starts to separate is after a local body goes nuclear. Then there will be a snow line for each of the elements once they are far enough away from the star to form ices. Plus there's the solar wind. Before the influence of a nuclear fusion object, the stuff is going to go to whatever object has the biggest gravity well relative to the stuff first. Stuff ain't gonna be like, "hold up...is you a staar...oh haaeell naw... I'll wait.."
...seems like there's no difference to me, the first object to get enough pressure in the middle gets to go boom. There are a lot of brown dwarfs because they drew the short stick and formed in a lean region or something else already sucked up all the good stuff.

Thanks for this video! I had been wondering for quite some time what was the difference between the two of them. Now I know!

A great man once said
"Pluto....c'mon in here. Have a seat.(sigh) Man... toughest thing I have to do around here. I'm gonna cut right to the quick Pluto, You're no longer a Planet!" - Planet committee
face). oh nooo...(followed by whining). Can i still orbit the sun?" - Pluto
"Feel (throws hands in air)" - Committee
"unintelligible crying, followed by rotating clockwise in circles" - Pluto

Great video. You are very skilled with your use of Space Engine and Universe Sandbox. It seems like there is still some confusion between what is a brown dwarf and what is a free-floating planet. Wouldn't it make more sense to define a temperature of an object...above which it is a brown dwarf, and below it is a planet or free-floating planet?

[borisbeloudus]

Near the center of the proto planetary disk is heavy metals and far away is water and other lighter elements.

Brown dwarfs I feel should get more attention. On your and other sites/youtube channels we can get very good information but I feel there is more to be told. Like: how old do they get and more importantly how do they change over time? Say they start as an M-type brown dwarf with essntially temperatures higher than some red dwarf stars...What happens to them. Also: why is it that there is a brown dwarf found with 90 masses of Jupiter, well beyond the threshold of the 75-80 Jupiters needed to get an object into nuclear fusion of hydrogen? This brown is to my mind even more mindboggling since is almost pruely made of hydrogen so there seems to be plenty of it to "ignite"....What can explin such a massive brown dwarf? It is now about 13 Giga Years old and classified as an L-subdwarf if I am correct. Etcetc. I would love to see more in depth information on these so called failed stars. A peculiar name btw. No one calls neutron starts failed black holes while in both cases the lack of mass is the reason they never became either a star or a black hole...
Finally I have seen astrophycists who actually have studied brown dwarfs calling them stars, like one who said that we need to rewrite history books since it is a possible that a brown dwarf might be at 1-2 ly from us. Which, according to him, means the closest star therefor is no longer proxima centauri. Pretty strange since a brown dwarf is not a star or we should say that hydrogen fusion is not what distinguishes stars from other objects.

Awesome video, though I have to say the term "failed star" irks me because they can't fail at something they never were. I find these objects fascinating.

[Murdervator]

I would really like to see you do THAT YES....STROKE heart...

[adamsapun]

Will you make a video about jupiters big red spot. I heard recently that it slowly disapears

[wjckc]

I think it won't be long before really hammer out what to call the celestial bodies. In a more sub divided and precise fashion.

[timlizzard]

Im late! Nice vid i love it like always

[bradlargay]

honestly the way I see it is if a gas giant orbits a star it's a planet and if the gas giant and the Stars barycenter is outside of the star then it's a brown dwarf

[eladioabelgaray]

very interesting video, especially the final part, while you walked away from the Milky Way, you could see an extraordinary view of the stars, on the other hand I would recommend that you upload a video about the brown dwarf SDSS 010448.46 + 153501.8 that is designed to have a weight of 90 java masses, (90 jupiters) is at a distance of 750 light years from the earth in the galactic halo, its mass exceeds with creses the limit of mass of between 75 or 80 java masses for the fusion of hydrogen 1 in its nucleus, supposedly this would happen for its so low metallicity that it would be about 250 times less than solar or 99.99 hydrogen and helium, in turn its age would be included in about 10, 000 million years which would also explain its " low "surface" temperature "of 1200 degrees Kelvin and type expectral T, you could see a video showing its surface appearance to see what it would look like, with the space engine or the universe sandbox 2, and explaining why its classification as a dwarf brown pe of its high mass, something similar to what you are with this video, (the Spanish version of this comment is below).

[VitruviusXXV]

Brown dwarf is a misnomer. They're a sinister looking blood red. Anyway, if they have a similar volume to Jupiter, yet have 30 or more times its mass, what then are they composed of? I enjoy all your vids Anton.

[SaulmanWinters]

Thoughts on the Electric Universe Theory, or Wallace Thornhill?

[williammontgrain]

I think finding a habitable planet orbiting a brown dwarf would be near impossible due to the radiation from its magnetosphere extending well beyond the otherwise habitable zone.

[ChefAdi]

What app is this? I want it to make a YouTube video with it

[AlmostEthical]

I prefer to think of brown dwarfs as cold stars rather than failed stars

[oisnowy]

Nice. I was about to ask: does anyone have any idea about the ratio of brown-to-red dwarfs? And then the video goes some length towards answering just that. I guess it must have been the obvious question. Let's keep this question in mind and see what astronomers can find out over the next ten years or so. We must have much better estimates by then.
