Got an idea of how Earth stacks up to other planets and stars sizewise ?
I thought i did as well .....til i saw this ...whoa

Thanks for sharing that Bogeyman I had no idea the difference in sizes.

If Earth was the size of a tennis ball ....How big would Antares be ? about the size of the Earth ,the Sun ? Bigger ?
It's mind boggling .........Mannnn that stuff is BIG

really gets you thinking

And to think we once believed the Universe revolved around us
In this scale of things we'd need to be a million times bigger to be knee high to a flea

Thats truely amazing. I didn't think there was that much of a difference.

I was going to consider saying that too bad Earth isn't the size of Jupiter (A ton more resources would be available), but if that were the case civilizations would take a lot longer to communicate and interact. We'd probably be far behind in our technology.

.......This reminds me of the song 'Its a small world after all'


Also if Earth were the size of Jupiter we would be about 7ft tall and if we went to Earth like it is we would be able to jump 20yrds (est.)

Man, Antares is huge. It makes you think how something like that could be formed...

Amazing.

Stupid sun. He ain't so big.

Big enough to be consuming hydrogen at a rate of 4 million tons every second for 4 billion years, and still only be half way through it's life.

Makes you feel a little insignificant, doesn't it?

I'd hate to be anywhere near that Antares (it must be a supergiant) Imagine what happesn when it becomes a supernova, but amazingly I bet there are stars larger than it

Actually I think we'd be a lot smaller, bipeds would be extremely inefficient because of the strong gravitational pull.

There's no doubt that there are stars bigger than Antares, and then you're still left with galaxies, clusters etc. It's amazingly huge.

It really shows how small we are in the greater scheme of things. The universe is vast and mysterious and we are far from knowing what wonders lie within the tapestry of it.

Antares and Belteguese are Red Supergiants The largest stars.

They are pretty through a scope, a beautiful red color. The only reason Sirius is the brightest star in the sky is that it is closer to us...it has a higher aparent magnitude while the bigger stars have a higher absolute magnitude.

Luminosity is also a factor, but to fully understand, you would need some basic knowledge on astrophysics- Wien's Law, Planck Spectrum, and Stefan's Law.

And there are billions of those in one galaxy, and there are a billion billion galaxies.........


Dribble......droool...........*thump*

I always thought that Mars was "kinda" the same size as us .I didnt realise it was so much smaller.
I just looked at that page again and it's even more jaw dropping the 2nd time.
I cant get my head around it to be honest ...it's hard to even imagine something being so biiiiiiig
something so large that the Sun is not even as large as a pinhead next to it
Are there Stars even larger do you think ?
And what does this say about the possibility of Planet size and how large they can be and how would that affect probable life on such planets....oooooh my head hurts

Thanks for the perspective Bogey!

Largest star.....

The biggest star I know in physical size is the supergiant star Mu Cephi about 1800 light years distant, and believed to have a surface that extends past the orbit of Saturn if placed in our solar system. The bright star Betelgeuse in Orion (shown above in a Hubble Space Telescope image) is about 1000 times the radius of the Sun, with an outer surface that would be out past the orbit of Jupiter.

Space is big. Really big.You just won't believe how vastly, mindbogglingly big it is. I mean you may think it's a long way down the road to the chemist, but that's just peanuts to space. Listen ...

Nice. Where did you find the pics? They cant be user generated right?

Man...

Uranus is huge...

Tee-hee!!

I was waiting for a Uranus joke. That was quicker than expected.

Man you guys are fast. I didn't even get to look at my post myself before you had replied. A friend posted me the pics, they are from NASA.

The great thing about them is they give the unwashed masses an idea of our solar system, the sizes involved, which numbers just can't convey. A picture tells a thousand words. The Earth could crash into the Sun and it would hardly notice. Pity Gallelio didn't have these pics ...

By the way, the correct pronunciation for Uranus is 'YOR-A-NOS', after the God now, so be careful.

Tell it to Otacon. He always does stuff like that.

I was e-mailed these diagrams a few days agoy, they are quite interesting. Stupid question, how did they derive the figures based on the diagrams?

Thanks

Thanks for posting.

If it was me doing it, I would of figured out the sizes of each object and then scale them, i.e. if we know that if Antares is 300 times bigger than the sun, than if the sun is 1 pixel wide, that would make Antares 300 pixels wide. Quite simple.

These are, undoubtedly, interesting and informative illustrations.

There have now been four seperate threads about these pictures so I have merged them into one.

Wow, I knew there were some big stars but this is just, just, well... * speechless *

Where's a nice jaw-dropping smilie when you need one.

Excellent find!

Can you imagine if there may be planets the size of our sun or bigger around one of those huge stars that contain life? The animals that inhabit the planet might be as big as Earth itself. What are the odds???????

Not good. If a body ever got too big it wouldn't be able to stop itself from undergoing fusion and becoming a star.

how big is antares in like miles or km? if you can measure it with thoes units or measurements?

The sun has a diameter of about 1.4 milliom Km (870,000 miles) Antares is about 700 times larger in diameter. In other words if you replaced the sun with Antares Mercury, Venus Earth and Mars would all be inside it and it would be borderline for Jupiter.

thats really big its kinda hard to comperhend (i cant spell it) something that big man... i cant think about that ne more it hurts my brain.

are those big red things stars?what about that white one?

Yeah, they're stars; the white ones aswell.

how come the stars are white?

Actually only 2 of the stars in those models are white, Sirius and Rigel.

Stars have different colours depending on their surface temperatures, the coolest are red going through orange and white to blueish for the hottest. Most of these colours are not easy to see with the naked eye (the eye tends to work only in monochrome at low light levels) but are obvios in photographic images. Some of the red giants (Betelguese springs to mind) are clearly visibly red to the naked eye. In fact the name of the star Antares literally means rival of Ares (Mars) because it's colour rivals that of the red planet.

Thought this was inconceeivable ,.. its pretty awesome . See for yourself

Now picture yourself! You would not even be a nanopixel in the biggest representation of the Earth in those pictures.

It was a very humbling experience.

I got these pictures in a bulliten on myspace and thought I would pass these along to inquiring minds of UM .

yes i admit the sun is quite small but we are rather lucky. due to that the sun is average. any bigger life cannot strive any smaller life also cannot strive. and also the bigger the star is the shorter it's lifespan will also be.

This also shows us just how lucky we are. Can you imagine the creator of the universe creating something so infinitesimal as planet earth to really shine down on this speck of sand in the universe and create us in his almighty image. The human ego, what a warped sence of reality!

Isn't it just fantastic? I've never really been able to "comprehend" the actual size of the Sun and other planets and stars until I saw this.

Woah. I never really thought about the sizes of planets...I've always assumed they're roughly the same size...really opens up the imagination.

And Antares...is it a sun or something?

Yes, all but the planets are stars. Antares wiki article

Sorry Waspie, didn't know there was a thread of this before.
