how long till the sun goes out?

Answer 1

not until he finds a date haha!!!

Answer 2

aproximatly 5 billion years(it burns faster as it grows older)
man, if we watch ourselfs; will be the last living beings on the planet, in i think less than half a billion years nothing will be alive ON earth, the atmosphere will have burnt away because the sun is getting bigger and closer. however, even though it is getting bigger there is a chance that the gravitational pull the sun has will decrease, and the earth may not be swallowed into the sun, but it will be a deformed giant melted rock, unrecognizable. then eventually, when the sun is a red giant, it will turn into a white dwarf, probably smaller than the earth, then it will finnaly burn out completely and become a black dwarf, the earth would not have any heat, and the core will stop, turning into somthing like cooled lava, it turns solid. and it will just float away, (if the suns gravitational pull loosens). if it doesnt then the earth will just be like a drop of water on a hot stove.........yeah.....

Answer 3

depends what you mean by go out.

The principle fuel source (Hydrogen fusion) will end in about 4.6 billion years. It will then burn Helium for about 500 million years,ad maybe carbon for a few hundreds of years after that. It will then shrink down to a white dwarf when it will shine by the slow release of gravitational energy. This will keep the sun going for about 15 billion years - or longer than the current age of the universe.

I wouldn't worry though when the hydrogen burning stage ends the sun will go red giant and it will be bye bye Earth.

Note on supernovae

For a star to go superovae (Type II) it needs a mass of about then times of mass of the sun. However stars of about the mass of the sun do undergo a "Helium Flash" when start helium core burning. The flash isn't nearly as big as a SNII but you don't want to be around.

Answer 4

Billions of years, so don't worry!

At the end, the sun (Sol by it's proper name) isn't big enough to go nova, so it'll become a red giant, ( all down to the way it burns its fuel) expanding out to around the orbit of Mars, which means, unfortunately, that the earth will be absorbed, extinguishing all and any life that might still be around, and after that, the sun will collapse into a black dwarf, gradually cooling away to nothing

Cheery, eh?

Answer 5

the sun will cease to be any use to us upon entering it's red giant phase, in about 4 billion years time. however, it will not completely go out for many billions of years after that, as it eventually becomes a white dwarf and slowly cools; the sun will probably emit some heat and light for at least the next 10 billion years, although after 4 billion years' time it will be much less than at present.

Answer 6

john...Supernova is not when the sun "burns out", its when the sun detonates in a catastrophic explosion with the force of roughly 53 billion billion billion billion billion billion 5 gigaton bombs. But the sun isn't the right kind of star to do that, or so they say. They say it will just slowly snuff itself out, so we should be safe-ish if we live that long, which this species won't. The scientists say that too.

now to the question at hand...we have 5 billion years to work with before the estimated demise of the sun. they say, as I mentioned above, that it will just slowly burn itself out as it runs out of fuel. we should be gone by that time-either extinct or moved to another planet. I'm not sure which yet.

Answer 7

In the last 100 years man has already managed to damage the planet at an ever increasing rate. Do you really reckon man is even going to be around when the sun finally burns out?

Answer 8

5 BILLION YRS. Surface area 6000 c. It converts Hydrogen into Helium It said to expand coving Mecruy, Venus and Earth. It will shirk back to White dwarf after an explosion.

Answer 9

About 4 billion years maybe.
It's the earth wobble we need to worry about - we're due another soon and it will wipe everything out.

Answer 10

A long long long time. I'm 30 and when I was in 2nd grade, they told me that it had a billion years left before 'Supernova'. (Ya know, til it burns out.)

Answer 11

we would leave this planet and could colonise some other planets and I think that It wont go out till we have that tech.We would have this type of tech in 3.4 billion years and If we die we will die by some other cause !
