How much longer do scientists think the sun will live?

Answer 1

Our sun will live until it is only 12.3 Billion years old. Now it is around 4.5 Billion years old. This meaning the sun will live another 7.8 Billion years. At the Red Giant phase of its life when it is 12.2 Billion years of age, it will only live another 100 Million years until it becomes a white dwarf. Also, when it is in the Red Giant phase, the Sun will consume Mercury and Venus and leave the Earth in extremely hot temperatures to where nobody in the world will live. ----

Our sun is a star and is not actually alive, thought it is very active. It is a star, and like many stars that are about the same size (mass), it follows a pattern of development on the main sequence. Our sun will burn (fuse elements) for a total of about 10 billion years. Since our solar system is about 4.6 billion years old, therefore our sun has another 5.4 billion years to go. However you must understand that the sun will change as it ages as it begins to fuse heavier elements. It is presently getting hotter and hotter and in about another billion years the earth will not be a very pleasant place to live. Towards the end of its life it will puff up to become a red giant and its outer surface will be around where the earth orbits. In the end it will blow off its outer layers in a planetary nebular and what will be left is a small hot core called a white dwarf which will slowly cool and fade. ----

Answer 2

The sun is about 4.6 billion years old, or about the same age as the earth. The life span of our own star is estimated to about 12 billion years, and as such it's not even half-way through. However, in about 5 billion years the sun will run out of hydrogen to burn into helium, and will start burning heavier fuels. This will cause to become a red giant, increasing in size considerably and its outer edges will almost reach the orbit of the earth.

Once all the fuel is gone, the sun will lose the battle with gravity and it'll collapse into a white dwarf, which is similar to a hot, glowing ember in your charcoal grill - just slowly radiating off heat and cooling down until it eventually will become absolutely dead and cold; the mass of a star, in a ball the size of the earth.

Answer 3

The sun is estimated to have 4.5 billion years left before it implodes on itself.

Answer 4

Its been in its main phase for about 4 1/2 billion years and should have 4-5 billion years left until it turns into a Red Giant.

Answer 5

The sun is approximately 4.6 billion years old.
