Hello

I heard from some paper that wrote the sun would fit over 20 million earth`s inside it .

And I was like :O

Anyway , I am wondering how big the sun is ... aproxx 20 earth`s ?

It's Mean Diameter is 1.392x10 to the 6th power, or 1,392,000,000 kms in diameter, which is 109 earths.

Thank you my friend

There's something wrong with the equation you used, WolfofWar. Normally, I'd correct you, but I'm feeling lazy and this could be a learning experience.

According to curious.astro.cornell.edu you can fit 1 million Earths into the sun.

The Sun has a radius 100 times that of the Earth which means that about 1,000,000 (1 million) Earths would fit into the Sun!

And our sun isn't that big compared with stars like Betelgeuse (beetle juice).

library.thinkquest.org...

One supergiant, Betelgeuse, becomes larger and smaller in diameter, sometimes reaching almost 600 times the diameter of the Sun. If the Sun grew to the size of Betelgeuse, it would swallow up Mercury, Venus, Earth, and Mars.

*shrug*

Blame Wikipedia, Not me.

Then again, I'm not the Forum's subject matter expert, so take it away.

All I really know is its big, and hot, and will destroy us all.

I was just refering to how you found the diameter (correctly, might I add), but it should have been the volume you were looking for. Umbrax got it though. Also, notice the tags.

Yes... Yes it will... I can see it now, there in the sky, silently mouthing the words, "Fear me..."

I have a question...whats the biggest star right now known to man? Describe its size?

posted on Feb, 14 2006 @ 10:11 AM
It's in the Pistol Nebula... If memory serves me right it's about 100 times as massive and 10-million times as bright as the Sun. There's a good chance I could be wrong on that though.

the stars name is LBV 1806-20 and is 150 times the mass of our sun and
shins up to a million times brighter.
so if you could fit 1million earths into our sun and this sun is 150 times more massive that would come out to trillions of earths .
this sun shouldent even excist acording to know physics.
and the whole area of space in this sector has manny funky stars .

Wow thanks for the info to both of you. It would seem this star is bigger than the Pistol star as cmdrkeenkid mentioned. Of course as the article mentions some theories as to why this star is still in existence, possibly affected by nearby stars.

Well, in any case, at 150 times the mass - it's going to be hell of a short-lived star. Remember, bigger means younger. The bigger a star is, the shorter it'll stay around for, since it burns up its fuel faster.

A star 150 times the mass of the sun though, shouldn't it collapse into a black hole almost immediately?

I think that they'll probably study it in order to determine how the cores of stars work. Assuming that the core is itself larger, then the mass/area may stay just above enough to cause it to collapse in on itself. This is, weakly, held up by fusion reactions so vigorously taking place within it.

Of course, when this sucker blows, it'll be one heck of a bang!

i know off top of my head that its 1.39 million km. wide and 110 earths wide. from school.

.

Article says " It shines up to 40 million times brighter than the Sun"

Just for perspective

Actually, they think it could be 40 million times brighter, but all of this is not known at the time. Another thing that's not known is if it's actually just 1 star. Read this quote;

"The high-resolution data prove that the object is not simply a cluster of lower mass stars, although it is possible that it is a collection of a few stars in a tight orbit around each other," Figer said. "More study will be needed to determine the distance and singularity of the object in order to establish whether the object is truly the most massive star known."
