does anybody know the year that the sun's energy will run out? If it does what planet whould you liveonandwhy?

No one knows, at it's current rate of energy useage, a few million years. Which planet would I choose? Can't, you & I are already dead, besides all planets in our solar system would be lifeless (no sun).

Brian is right, but I have to add a smart-ass remark that sun will burn up and go out in a few million years, but by then the humankind will either destroy itself, or find a way to move on to other stars.

The sun is about 4.5 billion years old and about 1/3 rd the way through it's expected life. Scientists have given us a glimpse of what to expect as the sun ages.\n\n1.1 billion years or so, it will become 10% brighter. This will cause the earth to become super heated, all life will be destroyed and the oceans will boil away. Then in another 6.5 billion years, it will double in brightness and burn its supply of hydrogen fuel in its core. The sun will swell and become bigger than what we see today.\n\nAt around 8 billion years or so, the size will increase to 166 times and reach as far as Jupiter. The color will be red and it will be known as a Red Giant, but once the hydrogen fuel is depleted and the sun has reached the outer regions of Jupiter, it will start to shrink, losing both energy and brightness as it quickly consumes it's helium in  in 100 million years or so..\n\nThen, at around 12 billion years, the sun will eject much of its outer layers and become a smoldering, collapsed core that scientists would call a White Dwarf, but this is not the end, for it has one more transformation. It eventually will become a Black Hole.\n\nIf you would like to see what the sun will look like when it becomes a White Dwarf, go to:\nhttp://www.physorg.com/newman/gfx/news/m2_9_large.jpg

Today is November 16, not April 1. Everything expending energy eventually uses up the energy. Even the sun will eventually die. You and I and the rest of the current human race will beat it to the punch, however.

The Sun, in 4.5 billion years supposedly, WILL start to swell. It will get bigger, and en-gulp Mercury and Venus. The atmosphere will evaporate, water will melt, and life will be gone. The sun will swell enough to devour the earth, then shrink, grow, Turn into a planetary nebula, then shrink, for the last time, into a white dwarf. Then In a few billion years, cool down to a black dwarf.\n\nThe reason the sun expands, In case you want to know, Is because of its fuel supply. The energy from the sun comes from nuclear fusion of Helium. When the helium supply runs out, The sun has to fuse hydrogen, therefore making the sun swell. The sun then will Shrink, once its helium supply is restored, grow again, then cast out a planetary nebula (For what a planetary nebula looks like, Look up the ring nebula) then it wont have enough hydrogen to grow back to the normal size...and become a white dwarf. Eventually, it will cool into a black dwarf and die.

In around 4 to 5 Billion years when the Sun is swollen in its death throes before it collapses into star known as a white dwarf . In fact the whole Earth will be vapourised.\n\nIf you mean by your question when will it be destroyed environmentally, then that's upto the caretakers of this planet wether that is humans or some other species.\n\nOtherwise the Earth will always have an atmosphere of one kind or another until the Sun begins to die.\n\nJules

Our planet will not die until the sun burns out.  Everything revolves around a cycle.  This planet has survived for millions of years all with life.  There will never be a scarcity of anything but certain species of animals.  Humans are far too smart to make the earth go to shame.  Since 1920 our knowlege has doubled 37 times.  Before then it had only doubled 18 times in thousands of years.  Earth is on the incline not decline.

Water is a necessity for life and that is based on temperature more so than which planet you are from the sun, it could be the tenth planet from the sun as long as the temperature is similar to ours here. \nBut with so many galaxies and suns in the universe I'm sure somewhere there is another world much like our own.\n\nHeres something you might like it shows everything that we are able to see in the universe and zooms down to our solar system.\n\nhttp://www.atlasoftheuniverse.com/universe.html

The earth will not explode.  No, whoever said the sun will go supernova failed pre-k.  Ignore them.  Anyway, the earth can not explode, nor can any other planet pretty muc.  The Astroid belt would be to small to be a  destroyed planet, for it would be smaller than pluto if all the rocks were to be put together.  The only way the earth could exploide is with the colision of and object about 4x the size of earth if it was solid...and that, by almost all laws of physics, is impossible.\n\nEdit:\n\nOh, your also asking for the end of the world.  Very well.\n\nThe sun is 4.5 billion years old scientists estimate.  The sun eventually, in 4.5 billion years, swell into a red giant.  It will expand very far, and the earth will be engulped.  Plant life will die, the earth will become dry, and very few organisms will survive.  Eventually, the heat will evaporate the atmoshpere away.  The sun might swallow up the earth, and the earth will be devoured and broken apart from gravity if im correct.  Edit any posts and correct me if im wrpong.  If im not wrong and you correct me, watch how badly I flame your ***\n\nEdit2:\n\nOmfg how many people dont understand!  My god, you idiots!  Comon, a planet getting sucked into a blakc hole?!  YOu retatrds!  Your kidding me right? If your actually voted as the best answer, then the world truly will explode!  You people know nothing in life!\n\nAnyway, at the guy who says the earths core is a neuclear reactor:\n\nThe earth yes might be getting hotter, but that is no reason for it to explode.  Im not saying im with the media, Im only saying that the earths not in any real danger yet.  Im saying that I think It will last some time...but you do have a pont.  I'll do some looking into it.  Gotta show this to my buds on other forums.  Afk.\n\nPs. Good job for playgerizing the whole article but 2 words, by the way!

The sun will get slowly brighter over the next few billion years.  Then, it will go through a red giant phase of expansion and contraction that will last another few hundred million years.  Finally, the outer envelope will blow off revealing a white dwarf that will slowly cool over several more billion years.

The sun’s history \n\n5 billion years ago, a small cloud of gas and dust began to compress under its own weight, or if your a creationist 5000 years ago. As more and more gas began to be crushed on the weight of gravity, hydrogen within the core began to fuse together. This fusion processes, one still sought by earth's scientist makes hydrogen into helium, and release’s incredible amounts of energy. This energy is converted into tremendous amounts of heat and light, which forms the energy source for our planet. Imagine the power you could amass if you were able to corner the market on the amount of sunlight hitting the earth. The cloud from which the sun is formed, fortunately for us, did not use all of its gas and dust to make the Sun; that which was left over, less than one percent of the original material, formed the 9 planets. Incidentally Jupiter could be considered a failed sun, that didn't have sufficient mass to start the fusion process. \n\nLuckily for us in the real estate business the sun has 3 to 4 billion years more of prime building time. As the sun begins to age more and more of its interior will be converted into helium. Once the sun exhausts its source of fuel, it will begin fusing helium into heavier elements. The heaver element carbon, the primary new fusion product, gives off a lot more energy than the similar production of helium. This excess energy will make your property on the sun even more valuable, since the excess energy could be harvest for your use. In fact as the sun pumps out more energy it cause the outer layer of the sun to expand and will engulf the inner core planets up to Mars. This lost of prime real estate will make your investment in the sun even more valuable, since the available area for building will be reduced. Not to mention but the sun's color will change to a pleasing Red color, a nice change of pace from the current yellow/orange hue our sun currently has. .

Astronomers will tell you the Sun is dated at 4.5 billion years old\n\nhttp://www.astro.uiuc.edu/~kaler/AstroBrief/chapter12/sunage.html\n\nThe Sun will one day become a white dwarf and be the fiery death the Bible claims God will bestow upon us.\n\nhttp://imagine.gsfc.nasa.gov/docs/science/know_l2/dwarfs.html\n\nPersonally, I think it's all a farce:\nhttp://www.celestialproducts.com/BA.asp\n\nor maybe I'm just angstrom's away from reality. hmm. I wonder, but not for too long as I may contract Homer Simpson syndrome.

Yes. If we don't destroy it ourselves, eventually the Sun will burn out and Earth will freeze (all stars eventually burn out), making in uninhabitable for humans. I suppose there is a chance we will have technology to help us live in those conditions (or maybe we will evolve to live in thos conditions) by then, but I doubt it.

Scientifically speaking: There is nothing that humans can do stop the sun from expanding. It will happen whether we like it or not.\nReligiously speaking: Your God should have wiped us out by then.\nOptimistically speaking: We will by then have space-travel and colonize space and spread our distorted DNA all over this universe.\nPessimistically speaking: We are freakin' dead.\nRealistically speaking: We can't even stop the green-house effect, how do you think we will stop a star from expanding its' fuel and dying?\nPersonally speaking: Scotty, beam me up!

The Sun will use up its hydrogen fuel in a few billion years.  At that point, it will shrink a bit because of the gravity of its own matter.  At some point in the collapse, the helium nuclei will begin to undergo fusion creating heavier elements.  This will cause the surface to expand and as heavier elements are formed, the Sun will evolve into a Red Giant.  Its surface will be somewhere around the orbit of Mars--thus vaporizing Mercury, Venus and the earth along the way.  The Sun is not massive enough to go supernova, only nova.  It will end its life as a white dwarf.

There is honestly no way that a person could answer that- besides a scientist. We can probably continue reproducing until the sun runs out of energy.

Our sun does not have enough mass or density to go nova.\n\n"The Sun is about 4.5 billion years old. it has used up about half of its nuclear fuel (hydrogen). In about 5 billion years from now, the sun will begin to die.\n\nAs the Sun grows old, it will expand. As the core runs out of hydrogen and then helium, the core will contact and the outer layers will expand, cool, and become less bright. It will become a red giant star.\n\nAfter this phase, the outer layers of the Sun will continue to expand. As this happens, the core will contract; the helium atoms in the core will fuse together, forming carbon atoms and releasing energy. The core will then be stable since the carbon atoms are not further compressible.\n\nThen the outer layers of the Sun drift off into space, forming a planetary nebula (a planetary nebula has nothing to do with planets), exposing the core.\n\nMost of its mass will go to the nebula. The remaining Sun will cool and shrink; it will eventually be only a few thousand miles in diameter!\n\nThe star is now a white dwarf, a stable star with no nuclear fuel. It radiates its left-over heat for billions of years. When its heat is all dispersed, it will be a cold, dark black dwarf - essentially a dead star (perhaps replete with diamonds, highly compressed carbon)."\n\n---and---\n\n"Our star, the sun, was born in the heavens about 4.5 billion years ago. Our sun is about 1/3 of the way through its expected life. Scientists are now predicting the following events during the remaining life of our star:\n\n    * In the next 1.1 billion years, its brightness will increase by 10%. This will super-heat our planet as a result of a severe greenhouse effect. All of the oceans on earth will boil away and all life will be destroyed.\n\n    * In about 6.5 billion years, our sun will double in brightness and use up all of its supply of hydrogen fuel in its core. This will cause the sun to begin swelling as it uses hydrogen from the layers surrounding the core.\n\n    * In about 8 billion years the sun will swell to 166 times its present size. This giant star will swallow up Mercury, Venus, and maybe even our Earth. Our sun will then be what scientists call a Red Giant because it will be very large and red in color.\n\n    * After all hydrogen fuel is used, the sun will begin to use helium as its fuel. This fuel will burn very quickly and only last about 100 million years.\n\n    * In about 12 billion years, the sun will eject much of its outer layers and become a smoldering, collapsed core that scientists would call a White Dwarf."
