It is postulated that towards the end of its life cycle, the sun will become a red giant, which will consume several of the inner planets, possible including the earth. Even if the diameter of the sun does not expand to the point where the earth is consumed, the increased heat and radiation due to the sun's closer proximity will exterminate life on earth. Eventually, the sun will collapse into a white dwarf.

What will the sun turn into when it runs out of fuel or fusion does this mean the end of life on earth?

At first, the sun will soon run out of its primary fuel, hydrogen. This will cause the sun's layers to expand, becoming a red giant. This will likely happen in 5 billion years. While scientists are unsure whether the expanded the sun will engulf the Earth or not, it will likely end life on Earth nonetheless.After it runs out of all fuel, including the heavier elements, it will begin shedding its outer layers and become a planetary nebula. Life on Earth would've almost certainly ceased by then.


What happens when the first stage of the multistage rocket runs out of fuel?

The first stage is jettisoned, to fall back to earth, as the fuel runs out.


What will happen to the sun when it runs out of fuel for fusion?

When the sun runs out of fuel for fusion, it will expand into a red giant, shedding its outer layers into space, before eventually collapsing into a white dwarf. This process will take several billion years to occur.


What is the fuel for stars?

The fuel for stars is primarily hydrogen, which undergoes nuclear fusion in their cores to form helium. This fusion process releases energy in the form of light and heat, which is what allows stars to shine and maintain their brightness over millions to billions of years.


What is the function of sun?

The form of the question seems to presuppose a "purpose" and scientifically the sun has no "purpose". But if you want to ask what processes are under way in the sun then you should ask that question. (Thermonuclear fusion of Hydrogen into Helium is the primary process). If on the other hand you wanted to ask what "effect" the sun has on the surrounding space, you should ask that question. (The sun heats up the surrounding space and material generated in the fusion processes are expelled)

After the sun runs out of fuel for fusion this will be the end of life on Earth?

Yes, but it is a long way off
