Starship Asterisk*

How big is the largest star on record? And where is it?

Do you want size or mass.

Some stars are only a few kilometers across with the same mass as our sun.

While others are 100 times the size of our sun and yet their mass is only a fraction.

Have a nice day

Thank you for your response Harry .

I meant size.

Would you be able to refer me to a website or like that answers all the basic questions on the universe that one might ask e.g how old is the earth? Do we know if there is an order in which our planets were formed? etc.

Welcome em

I find that http://www.nineplanets.org was always a good source for info for the solar system.

As for massive stars - try googling 'Eta Carina' and also 'Wolf-Rayet Stars" - they're pretty big....

Thanks Empeda 2 .

Have a great day!

Thanks Dani, that's exactly what i was after!

The universe simulator Celestia makes a vivid illustration of the differences in diameters stars can be. I took these screenies from within the program.


Here's the Sun, as seen from Saturn, at about 9 AU (Astronomical Units...1 AU is equal to the distance from the Sun to the Earth):



Just a tiny yellow dot.

Now here's the red giant Betelgeuse (in the constellation Orion) at a distance of 9 AU:



The giant doesn't even fit in the screen. Also, the distances are from the surfaces of the two stars...

Hello Dani

Thank you for the links

These Giant stars are very interesting.
Has anybody calculated or estimated the mass.

I'd love to know the size of the Core.

How is the size of the core calculated?

By guesstimate and by the temperature and by the graviational effects on the surrounding space bodies.

The problem with distant giants is that you maybe looking at a multiple of stars looking as one.

My Question is that if you have a star 5 million times the size of our star. Why does it not behave like a black hole.

Because we're talking about physical diameter/volume - not the mass of the star.

Something fishy is happening with the giant stars. There is more than meets the eye.

What do you mean Harry?

In the Links above they are talking about stars 5 to 40 billion times that of our sun.


Something does not add up

I may need sleep
