[monmarfori]

It is located in the constellation Sagittarius. this is the pistol star. with a mass of 200 solar masses
but the wiki says (possible original mass)
http://en.wikipedia.org/wiki/List_of_most_massive_stars

[monmarfori]

Pistol Star have 200 solar masses. while A1 has 114
and A1 b has 84
what if i confuse

[Naru523]

O.O

Massive Star: Pistol Star?
Largest Diameter Star: VY Canis Majoris

[Dan Dixon]

And note this from the link provided by monmarfori:

"The masses listed in the table are inferred from theory, using difficult measurements of the stars’ temperatures and absolute brightnesses. All the listed masses are uncertain: both the theory and the measurements are pushing the limits of current knowledge and technology."

how about vy cma mass

[SuperNova]

wait there's a bigger one: LBV 1906-20

[Naru523]

5 million times lumiousty...

[monmarfori]

and vy cma is the largest star

[TheListo]

Wow..  Amazing. 
I wonder what would happen if it was closer to us...   

[monmarfori]

we would die if VY Cma was near on the sun

[Naru523]

^ He's right, its the size of Saturn's orbit. Like 5-10 AU.

[Naru523]

Yep, 10 AU.

That's luminosity

[monmarfori]

how about the bluest star? it is LBV 1806 20 also

[Bernier77]

Depends how close "close" is.
Our atmosphere/magnetic field wouldn't hold off much radiation from that monster, so we'd die off pretty fast.

[BladeOfTheListo]

We'd probably shrivel up instantly because our bodies wouldn't be able to take the heat.
Fires would randomly break out all across earth,
All the water would evaporate and there'd be one thick blanket of cloud.
That's what I think would happen.
So lets be glad it's not closer.
