guess in aproximatly how many years will the sun go out?

According to answers.com, the sun will last another 6 billion years, so you don't need to worry about it. It also says that it will turn into a white dwarf. Yet, the other source says that it will last around 5 billion years until it turns into a white dwarf. Then, it will cool down, taking billions of years, then turn into a black dwarf.\nhttp://www.enchantedlearning.com/subjects/astronomy/stars/lifecycle/\nhas a diagram to show the cycles of stars like the sun.

we still have about 4 billion years to go on that\n\nhttp://en.wikipedia.org/wiki/Sun

when the sun dies and runs out of fuel. Then the earth will die because of no photosysthesis.

Yes but it will be a long time away. In 6 to 7 billion years, stellar evolution theory predicts our sun will evolve into a red giant  and will probably completely surround the Earth. I don't think I will be around then.

Probably one more year

I suppose in time it will die out.  Our sun is nothing more than a star and they do fade. As for whether or not it gets smaller or not but it will fade, get cooler, and less bright.  I would think that meant getting smaller too but I am not sure.

Depending on its position in the oval orbit it has around the sun, the earth gets sunlight 8.317 minutes after it is emitted from the sun.

Sun has finished its half of age and after some billions of years its gonna die. In the same way earth will be getting cooler it is gonna die.\n\nSun is a star. It will become a red supergiant. It's size will increase tremendously and it will gulp down mercury and venus. The temperature on earth will be unbelievable. Then it will become supernova and then there are three chances for sun to become 1. nebula  2. Neutron star or the worst nightmare 3. black hole.\n\nAbout dying here this one too. If the night sky is clear and with your naked eyes if u see in the right direction u can see andromeda galaxy - which is light years away. It is said that billions of billions of billions of years after...one day milky way (our galaxy) and andromeda will clash\n\nOr else talking about earth if not after billions of years when earth will die may be a little earlier ya earlier than sun becoming the red supergiant...the life especially human life may be in a serious danger. The threat is of asteroid impacts in 2014 or 2029 or 2880 or adverse climatic change in 2100 or another ice age!\n\nThere is a theory of Wormholes. Through these we can travel from one point of the universe to the other with a speed more than or equal to that of light. May be then we will be able to go somewhere.

tomorrow the sun will rise

Yup. The latest will be 5 billion years from now, give or take a few hundred thousand. By then the sun will either:\n\n1) engulf our planet (very unlikely, but will come close enough to vaporize our planet)\n2) Die and not engulf or vaporize our planet and within days our atmosphere will freeze and fall to the earth in the form of ice.

Total life span=8billon+yrs.\nIt may last for another 4.5 billion years.....(and counting)
916358
Not sure about annual total, but today the sun rose there at 6:57 AM and set at 4:50 PM... An annual total would average out to 12 hours of each, I would imagine

From the Wiki,\n\n"In about 5 billion years, the Sun will evolve into a red giant and then a white dwarf, creating a planetary nebula in the process."\n\nHumans will probably be long dead before then or will have moved on.  In a few billion years, the sun will get too hot for Earth to sustain life, but it'll be a while before it finally "blows up."  More accurately, it will actually implode and slowly become an inert mass.

About 50 million years for energy generated in the Sun's core to reach the sun's surface (the photosphere). (Source provided below.)

yes will the sun goes out or when god chooses.

very long. this is because the sun is a very large star and will take billions or rather trillions of years. when it does burn out however, it will be big enough to swell so big that it will swallow mercury, venus and possibly earth ^^ good luck

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. \n\nAnd no, incase someone posts it, the sun will not become a black hole.
