Why is the sun so big?

Question

how is it so big?

how did it get that big?

Answer 1

It simply managed to accumulate a lot of mass by gravity.  As star sizes go, the sun is about as average as you can get.  The latest data gives its age as 4568.5 million years.

Answer 2

I'd love to look it up but, unfortunately don't have the time.

Answer 3

It's a burning star.

Answer 4

to to www.youtube.com they'll tell you a lot about stars and earth and sky.com is also a sourse of knolege

Answer 5

its the same size as similar stars- its just closer.  also, different types of starts are different sizes.  remember it is a self sustaining source of fusion that will last 10 billion years, so its gotta be pretty big.

Answer 6

Well, any stars including the sun are formed by Hydrogen that goes to nuclear fusion.. all those Hydrogen atom are bounded together by gravitational force..The more gravitational force the stars has, the more bigger it gets..  

Answer 7

Big compared to what? I'm serious. It's just a middle sized star. The Universe is mind boggling. As the alien's said in the Woody Allen movie, "These are the wrong questions!"

Answer 8

its  not so much the sun being so big, but the earth and other planets are so small.  the sun is made of gas which can expand, while earth and many other planets are solids. And big things attract small things.  There are many stars bigger than our sun.

Answer 10

Big compared to what? A star has to have a minimum mass for the internal pressure to suffice to trigger the nuclear fusion process that characterizes stars. Jupiter is too small, for instance.  

Answer 11

In relation to the other stars, our sun is a medium-sized star. Just for comparison, the variable star VV Cephei is a billion miles in diameter, or about 1,220 times bigger than the sun.

Then there are small stars like Wolf 457, which is 3/1000th the size of the sun.

Answer 12

I don't know, but its a good thing stars are big or else all planets would be frozen and there would be 0 intelligent civilizations in the universe.
