how and when will the sun die ???

Answer 1

The sun will die because the hydrogen inside it will eventually be used up. This will create enormous pressure and make the sun increase in size, in fact so large that it will engulf the earth. This enlargement is called a red giant. Then it will blow up and all that will remain is the core or a red dwarf that may collapse in on its self creating a black hole. And all this will happen in about 7 billion years, so no need to worry!

Answer 2

The sun is at the middle of its life span. Inabout 3 billion years it will exhaust its supply of hydrogen fuel and begine the fusion of helium. When that happens it will turn into a red giant star and greatly expand its diameter. Which would expand beyond the distance to Earth and I believe Mars too. There is some new science that suggests that the planets will be pushed out so the Earth would not be swallowed up by the sun. None of us will live nearly that long. But there is a chance that the I.R.S. will still be collecting taxes.

Answer 3

Well, the "dying" of sun itself takes about 1000 years, so if it started we would know. Here's what happens: Our sun is a Main Sequence (medium-sized) star. (So, it will not go through super nova. Although, it will burn up it's core someday). It's "fuel" is hydrogen. This "fuel" lasts for few billion years until it burns up. Scientists say, it won't happen in next 2 billion years. First, right after the Hydrogen burns up, Helium core heats up (result of contracting under gravity). Then, the fusion increases around old, burnt up core, which releases a lot of energy, thus making sun a lot biger and brighter (temporarily). That's when sun turns into a Red Giant. That's a fairly fast process: only few hundred years (that's fairly fast process compare to how long it "lived"). Once temperature reaches about 100 million degrees Kelvin, it slowly starts to cool down. Eventually, it turns into a white dwarf, and then into a black dwarf (black dwarfs don't exist yet, cause process takes few TRILLION years, although we have seen a white dwarfs. There is no way of seeing black one, cause... well, it's black!). Although scientists say this will take few billion years, I believe sun and everything else will burn up on judgement day.

Answer 4

I don't think the Earth will last as long as the sun. So I don't think we have anything to worry about. The way we use oil the Earth will die like Mars did. The oil is what keeps the enter core of the Earth burning. Which we need to live

Answer 5

The sun will die in trillions of years, recently scientists think that it will blow up in 6 years.

Also, the sun will be recreated after Judgement Day

Answer 6

the sun will die when i turn 100 and i die.

Answer 7

horribly........
about 4.5 billion years from now, the sun is going to be a red giant star. it will swallow earth mars and perhaps jupiter and pull the rest closer by gravity. a red star is cooler than the suntoday, but its going to be hot enough to melt earth. a million years after that, it will start falling 'into' itself and become a dwarf star. white and very very hot. then it will result in a supernova explosion and disappear. well technically it will become a black hole. i dont think u'll be around to see it.

Answer 8

well the sun will explode in 500,000,000 years or turn into a black hole or die out. it happens to allllll stars and will happen 2 the sun.

Answer 9

the sun is a star so it will burn out. i think like in 2 billion more years so yeah u have time to take in the sunshine.

Answer 10

In about 6 billion years, we've got a while yet.
