will the sun ever die?

Question

likes stars that burn out, will the sun die someday?

Answer 1

Yes in about 5 billion years.

Answer 2

The Sun will last about 5 billion years as it is now, a so called Main Sequence Star.

What is really interesting is what happens after the Hydrogen has been used up in the Suns core. At this point in our Sun's life the central part of the Sun, its core, shrinks and heats up and its atmosphere will expand to cover the Earth, and possibly Mars. The Sun is now called a Red Giant Star. If you can find the constellation Orion, the bright red star in the upper left hand corner is a Red Giant called Betelgeuse. After only a few million years the core will shrink again and the our Suns atmosphere will be blown off into space to become Planetary Nebulae. What will be left is a type of Star called a White Dwarf. This will last for many tens of billions of years, slowly cooling and getting dimmer. So, our star, the Sun, will last for 5 Billion years as it is, a few million years as a Red Giant, and finally tens of Billions of Years as a White Dwarf.

Answer 3

Yes.

The Sun will use up all of its Hydrogen Gas in about 5 Billion Years. The death of the Sun will begin somewhere along in that time period and the Sun will expand four or five times its normal size and consume everything in its nearby vicinity. Most probably Mercury and Venus will go first and Earth is a good possibility also. In any event, the increase in size of the Sun will produce excessive heating on the Earth and everything will be burned to a cinder. All water supplies will be evaporated, everywhere.

Answer 4

Saw this on discovery a few days ago.

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.
As 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.
After 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.
Then the outer layers of the Sun drift off into space, forming a planetary nebula exposing the core. Most 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!

Answer 5

Yes, all stars die. It will use most of its hydrogen and start fusion of helium in 5 to 10 billion years. It will expand into a red giant and absorb the inner planets. It will fuse ever heavier el;ements up to iron. When its nuclear reactions ghacve gone as far as they can, it will be a dead star.

Answer 6

Yes. The sun will finish fusing hydrogen, then it will begin to fuse helium. This makes the sun turn into a red giant. Finally, the sun will collapse under its own mass and turn into a white dwarf. But don't worry, this won't happen for a very very very long time. :)

Answer 7

Yes! The law of nature. Regeneration of (effect of). Why does the other stars shine most than the others. The fire in the universe is not eternal the same as on the earth.

Answer 8

Yes, all stars die when they burn out their fuel. It won't happen in your lifetime though so don't worry about it.

Answer 9

Yes, estimates vary but it is not expected to last longer than 4 billion more years.

Answer 10

Yes, it will, around 50 BILLION years from now. That's a very, very long time, and humans would probably have been extinct by then, so don't worry!
