Planets and Stars (Click [Show More] )

[@kvmairforce]

No matter how many times I look at these videos, I still find it hard to fathom how big some of these planets and stars are.

[@sheepmaysafelygraze8360]

this is the first video I ever watched on youtube, like 7 years ago lmao

[@Nectarian]

:-)

[@Faren_]

The First Video on KZbin is "Me at the zoo" it was Uploaded on Wednesday 23rd March 2005 8:27 P.M.

[@29seconds.]

@@Faren_ he said the first video he watched. bruh

[@tsferg]

Oh mighty lord, thank you for creating these massive stars, just for us! You never cease to amaze me with your gifts!

[@Willsxmo]

I watched this for the first time wheb i was like 7, now im 13 and ive been searching for it for years

[@VadixeM]

Gosh... I remember times when I've seen it for the first time. Probably that's the moment when I started listening to dnb. gj man

[@Em183]

I like this video because of the music as well. The beginning reminds me of the Megaman video game I played as a child.

[@owlcowl]

This is the most graphically appealing and data-rich of the several planets & stars comparison videos (hardly the best music, tho). Congratulations to its creator. However, i would point out that the planets are shown as much smaller than they really are relative to the Sun -- Jupiter's diameter is just over a tenth that of the Sun's. Since this video was produced, new measurements have determined that Betelgeuse is actually larger than Antares; otherwise, the star size lineup is accurate.

[@dan4272]

Nice animation to scale, I did one of the solar system with the plants in there orbits to scale but they were like dots in the end haha... its also worth pointing out that larger stars have larger habitable zones so the likely hood of there being more than one planet like earth in orbit is therefore higher ! ;-)

[@siscorskiy]

Amazing video man, its good to see someone who knows alot about these stars and such. Sweet music too ^^

[@Starchild91]

That. Is. Insane. I think my mind just exploded. I can't even begin to understand this.

[@pacepertutti]

ah yess! Humanity goes about thinkin that we're the only thing that matters in the universe. I like planet size comparison videos .. they provoke us into asking serious questions about ourselves and the Universe that surrounds us. Great video ... thanks for uploading

[@HighCod]

Proper music for this video! ""The universe is fantastic"" :)

[@sharpentheaxe]

Very nice animation. Love the music selection.

[@Nectarian]

@isakilla1 =NOTE=- This video was made BEFORE "VY Canis Majoris" was listed as the largest known star, When this video was made 2006 by it's author JAXXrr, the star "VV Cephei A" was listed as the largest known star. as a side-note the sizes are an approximation VY Canis Majoris 1800 to 2100 Solar radii VV Cephei A 1600 to 1900 Solar radii it's strongly believed that Canis Majoris is the larger of the two however it's possible that Cephei has the greater radius

[@Nectarian]

Sirius B is a white dwarf and it's mass is nearly equal to our Sun however it's size is about that of the Earth. (it's very dense!) Sirius A: the star featured in the video and is the brightest star that is seen from the Earth at night has the Stellar classification type A1V

[@blindandwatching]

IIRC they can measure the red shift of the light against the emission spectrum and estimate a temperature and a distance. The size can be determined from the color and temperature.

[@ExtraNoise]

I'm glad you read the More Info. Good work.

[@Nectarian]

true this is a known error, also on a side note VV Cephei in was listed as the largest known star in 2006 when the video was made by jaxxr before VY Canis Majoris was listed as a probable larger star.

[@iBGalaxy]

Those stars are gigantic.. I wonder if there are planets out there as big as those stars. Earth is so smal even when compared with Neptune and Uranus.... The Universe is so interesting!!

[@Nectarian]

It's true that VY Canis Majoris (1800-2100 Solar radii) is thought to be larger then VV Cephei A (1600-1900 Solar radii) however there is some overlap VV Cephei A could be the larger of the two, please read the (more info) next to the video for more info on why VY Canis Majoris wasn't used at the time the video was made by jaxxrr

[@BrightOranje]

It's named after the nebula in which it's located, the Pistol Nebula (which is shaped like a pistol, I guess). It is indeed a weird star - it's one of the most massive known stars and is located near the center of the galaxy.

[@wildzach]

VY Cm has the potential to be the largest, but not necessarily. It's possible size range overlaps with VV Cep A

[@VeritasAbsoluta]

VV Cephei is huge. I just looked up the numbers, and if VV Cephei was to replace our sun it would fill up the solar system almost to the current orbit of Saturn.

[@PhoenixTsukino]

This was so awesome. We watched this video in Astronomy 101 today cuz we were talking about each of the planets. Someone in class mentioned this video and we watched it. Dr. Clark's Astronomy 101 class from the University of South Alabama gives you 5 stars!!!! ^_^

[@mocroae]

JUST WTF!?!?! that looked very interesting and cool, earth is soo small

[@InTheN1ght]

Nostalgie

[@upsideadown]

hrbear It is currently accepted that a dying star 4 solar masses and upwards would be massive enough to collapse in on itself and form a black hole. A lesser star such as our own sun lacks the mass and therefore gravity needed to create the intense pressures that cause black holes. Gravity kills solar mass = 1 sun

[@copkhan007]

These stars are huge and only a small fraction of our galaxy milky way. Imagine how mighty is the one who created it all.

[@juniorgeneric]

@Nectarian And sandwiched in between VY Canis Majoris and VV Cephei A is WOH G64 AT 2000 Solar Radii so it is in fact possible that WOH G64 is in fact the largest. We just don't know.

[@Nedyah74]

I really like seeing all of the NINE planets all compared by size.

[@blindandwatching]

There is a theoretical maximum size for a star. The fusion in the center reaches a point where it totally overcomes gravity and the whole thing explodes. Of course in a few thousand years you will probably be able to watch real stars go super-nova on pay-per-view.

[@OmriGazitt]

Nice video... cool depiction of relative cosmic sizes. Some of the comparison figures appeared to be wrong though. Earth's diameter is approx 12800km. The sun's diameter is approx 1392000km. The ratio is more like 109 (i.e. the sun is 109 earth diameters), not the 342 earth diameters that the video quoted around 1:05. The same error (by the same margin) exists for VV Cephai at 2:20.

[@Tigeron1a]

And youre right, the gravity of a star like that is probibly higher than that of the sun but still a great deal less than its volume sence the density of the vv Cephei is much less than its size. Shrunk down Im willing to bet it was the size of Rigel at one time.

[@Hannah_Otis]

Fantastic stuff; love the music too.

[@Nectarian]

It's true the that the largest known star is VY Canis Majoris however this video was made before this was known, a star larger still maybe discovered in the near future. I invite you to read the addition information about this video that JAXXrr made in 2006 in the notes located where it reads (more info) in the upper right corner, thank you.

[@xaiano794]

size does not directly relate to brightness (although obviously this is a factor) and has a lot more to do with mass and density of a star. Despite how big they are most of these are under 150 solar masses as the more massive a star is, the more energetic it is and the more it pushes the outer layers outward with the pressure of the light generated.

[@petisnnake]

@ReXt)n07 "you can find out how big they are from the amount of light they projects" Incorrect. You find out how big they are based on the speed at which other stars move around it. The bigger the gravitational pull -> The bigger the speed -> The bigger the star.

[@fieryspirit]

Pluto is a dwarf planet, along with Ceres and Eris. Their gravity is sufficient to have hydrostatic equilibrium and they aren`t satellites (moons, if you will). Eris is actually larger than Pluto and it`s orbit is further out than Pluto aswell. Ceres is found in the asteroid belt.

[@OnTheRun167]

This lets you know how exponentially small we really are. That's just a handful of planets and stars. There are billions upon billions more planets and stars in the universe.

[@tsferg]

I was only kidding. "That's the same as giving a chocolate bar to a molecule" What a strange analogy.

[@tsferg]

Yes he made the whole galaxy for us to explore. The majesty of His works are truly amazing.

[@insightfulgarbage]

Temperature being related to how fast atoms are moving, it's also and more importantly the point where atoms don't move anymore. How do you make the atoms moving even less than atoms that are not moving at all ? Following the same principle, a maximum temperature could be in theory infinite but, in our universe, would be the temperature attained by a theoretical machine that uses all of the energy in the universe to convert it into heat and concentrate it in one point.

[@aeonflux67]

The music is really beautiful. Soft and melodic. Its easy to get hooked. AAAHHHHHHHh I CANT FRIGGIN LIE ANY LONGER....IT SSUUUUUUXXXXX NECTARIAN......replace id dude with something classy like Mozart or Beethoven or Vangelis. Anything.

[@1CME90]

Yes,the size of these stars is hard imagine. If you scaled our earth to our sun and humans are like 5foot 9inches. Then if there were an earth like plant around VV Cephei and it was scaled like our earth is to our sun then that means if there were humans on that planet that they could be like 1000feet 9inches, the scale for everything could go up. Sorry for saying so much, I have alot to say about the universe we live in.

[@dandy6z]

واااااااااااو خيال لايوصف يالله كم تمنيت ان اعيش في الفضاء يارباه

[@botisonny]

stars starting from the sun...nice vid:)

[@proinsiaspad]

Thanks you Natesutera. Do you know that NASA still has some kit on the moon left by the later Apollo missions that they communicate with on a monthly basis..? The Apollo program was born out of the Cold War, and took place during the Cold War. How could you bluff 6 missions that with the high technology that both both China and the Soviets had at the time?

[@Nectarian]

@jensypoops VV Cephei A, now the ≈ 2nd largest known star, If placed in the center of the solar system would likely extend past the orbit of Jupiter and approach that of Saturn. the largest known star VY Canis Majoris ( Assuming the ≈ upper size limit of 2100 solar radii,) If placed in the center of the solar system, radius would beyond the orbit of Saturn. btw Saturn's Minimum Distance from Earth is 1.2 billion km (746 million miles)!

[@YuRiSunga]

Correction: •Jupiter, Saturn, Uranus, and Neptune Have All Rings. •UY Scuti is the Biggest. •Vega and Deneb are White. •Pistol Star is Blue. •Moons, More Dwarf Planets and More Stars, Objects, Buildings, Places, Mountains, and Asteroids are Included. Nebulae, Clusters, Galaxies, Superclusters, Galaxy Filaments, and the Observable Universe are Included.

[@raiwserkoopa2221]

This was uploaded in 2007 when w cephei was the largest before canis majoris was invented. so try again.

[@mariobusrailwayfans5683]

and Betelgeuse Bigger than Antares

[@JcDizon]

VY Canis Majoris should be in the video, its the largest known star currently, even larger than VV Cephei

[@BulletMagnetOWI]

The Earth is a very small stage in a vast cosmic arena. Think of the rivers of blood spilled by all those generals and emperors so that, in glory and triumph, they could become the momentary masters of a fraction of a dot. Think of the endless cruelties visited by the inhabitants of one corner of this pixel on the scarcely distinguishable inhabitants of some other corner, how frequent their misunderstandings, how eager they are to kill one another, how fervent their hatreds.

[@gatewaytoheaven11]

is it me or do u feel overwhelmed when seeing this?

[@indrajeet]

I wonder what would happen if one of these super stars in our galaxy went supernova!! Would we be able to see a glimps of the blast in the sky?

[@HitomiCOD2]

now this video really deserves these two words: HOLY SHIT!!!!!!!!!!!!

[@brox114]

Excellent video who ever made it... But, Sun is 109 times bigger than Earth (not 342x) - 109 diameters. And now, the largest star discoversd is VY Cannis Majoris (also red hypergigant) with approx. 2 920 000 km radius

[@36chocolas]

Makes you wonder about life and if the things we worry about, ARE they really THAT important..?

[@roguerock22]

Question using the following 'assumptions' or estimates just for fun: Assuming the 1999 Hubble Survey estimate was accurate on the # of galaxies in the universe being around 125B (Billion), and the avg. galaxy size being only half of the Milky way's size being 50B stars, and that there is only 1 Intelligent species per 2000 stars, about how many Intelligent species could there be? Simple algebra , I know, but I just wanted to ask a few peers and talk about it. :) Comment back, Hoya

[@davidslifeinmotion]

This biggest thing in the universe is well... the universe, lol! Actually the biggest thing in the universe are superclusters, followed by Clusters of galaxies, followed by galaxies, followed by arms of galaxies, followed by fluffs, followed by solar systems, followed by stars, planets, and smaller objects.

[@spitfiregirl110]

VY Canis Majoris is the largest known star. It dwarfs the Cephei star!

[@abysalhydra]

lol amount of times i heard that, i never thought of it like that

[@ssuuppeerraalleexx86]

Very coooool video!!! Good work. :)

[@aeonflux67]

VY Canis Majoris is now the biggest. It takes 8 hours for light to go around its circumference. It would fill out our solar system if it replaced the sun to the point Saturn occupies now. But you wouldnt swap it for the Sun as it is estimated to hypernova by 3200AD. Our sun stays with us another 5 Billion years. We hope./

[@MindLessWiz]

@tek87 Closer to a hundred thousand years, actually.

[@mexicaneskimos5]

INCORRECT!! VV Cephei is big but no where near the biggest, the largest known star is VY Canis Majoris!!

[@DrumOfFury]

I wonder if they ever come to think of this way, as VY Canis Majoris be the size of the earth and some other star as big as VY Canis Majoris? That something to think about since the Universe too huge. Never know.

[@Nectarian]

The reason the stars looks as they are becoming smaller is because there is no way to make your computer monitor grow larger and larger, that why the video zooms out in order to give side by side comparisons, it's not like Mercury is the same size of the Sun you know.

[@jaxxrr]

the site in your description is pretty cool (atlasoftheuniverse)

[@Andrei2000PC]

Amazing to be the only creatures in the universe.

[@Shortay1325]

Dude.. i just figured something out! Distance between Earth and Sun is like 149 million Km away. But the Planet/star Deneb is 201 million Km away.. that means u can Put Deneb inbetween the Earth and The sun. Pratically filling the cap from here to the Sun. Isn't that just fricken crazy? dam that is unbelievable

[@BieberSucksCock100]

To all you idiots saying this video is wrong and that majoris is larger, this video was made 5 years ago. Majoris was a recent discovery.

[@bennihana123]

That is frakking awesome

[@kmart43210]

My science teacher showed us this vid in science class, it is awesome! Does anyone know this song? I really like it.

[@indrajeet]

wow!! There are stars that are as bigg as our solar system!!

[@Feroxylos]

the music is awesome

[@jensypoops]

@Nectarian Thankies and wow thats huge :O but then again the lil star wont live as long as ours coz ours kicks ass woop woop

[@bradwatson7324]

Wow. This video makes you stop and think how small Pluto really is.

[@ArmanFanatic]

COOL MUSIC!

[@Compguy321]

Well done!

[@Drydareelin]

your right, w cephei isn't the biggest star, the hyper giant is called 'Cygnus Ob2 no. 12'

[@kakakkakashi]

nice video!! i know that more than 5 is bigger than sun :o

[@fieryspirit]

Of course you haven`t thought how many stars and galaxies, and the distance involved between them. Then you'd feel really small and insignificant.

[@Osea-hello]

this is a sweet vid(: hey Asiaaaaaaa, idk if ur gonna see the comments like u said u would, but if you are, hiiiiiii!xD lol

[@gingy717]

Does everyone know about when stars near the end of there life they like turn into red giants and swell to like 2 times there size. Could u imagine that vv cephei planet going giant. COOL!!!

[@ImagesByDavid]

Im preety impressed with your video. Watched a few times now. Is VV Cephei a planet or a star? Whats the difference?

[@36chocolas]

@GregDarkness I know right?! Either A. we are among the numerous other 'living' things in this universe but haven't looked hard enough to see the other things (probably since we're all so absorbed by our petty lives we continue to live) or B. There is some higher power that just wants to show us how amazing they can be and what they can create (I'm a Christian so I'm happy to believe either, I think it's definitely possible that we aren't alone cause the universe is just so enormous it's not ex

[@Fuad0]

AMAZING!! if VV Cephei is the biggest known star, how big is the UNIVERSE?

[@sheensalvador9965]

Biggest star: NML Cygni, the description was edited/changed in 2012.

[@olswellmaps]

@boldarbiter check when the video was made... ....it was still classed as a planet then

[@wildzach]

love the music

[@ivan042]

awesome vid

[@x2xlucyx2x]

So awesome

[@edwardus25]

@isakilla1 wrong the biggest star ever knowing is now R136a1 in tarantula nebulla maggellan

[@cookieandfriends]

I love this video, we watched it in science

[@harkonnenn]

unbelievable!

[@insightfulgarbage]

Well that's a good point, but It was a mistake of mine to talk about a point where I sould really be talking about a space. (To put all of the matter in a point would require an infinite pressure, which would require an infinite amount of energy which we don't have) In simple terms there must be a maximum temperature for there is a limited amount of energy in our universe. But i might be mistaken, I'm no specialist ;)

[@madamen13]

Thats FREAKY!

[@gswarner]

you had me at Pollux

[@Yoooovi]

Its a verry good film...and there r more :WY canis majoris

[@whiterottenrabbit]

The fcuking stars kept getting bigger and bigger! 8-)

[@popemendelsohn]

Imagine being invicible and floating over V V cephei. It's too hard to even think about.
