How long will it be till the sun runs out of fuel you think?

Answer 1

G'day Tan,

The Sun is about 4.6 billion years old and is about halfway through its main-sequence evolution, during which nuclear fusion reactions in its core fuse hydrogen into helium. Each second, more than 4 million tonnes of matter are converted into energy within the Sun's core, producing neutrinos and solar radiation. 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. When it becomes a red giant it will absorb the inner planets including the Earth.

About 74% of the Sun's mass is hydrogen, 25% is helium, and the rest is made up of trace quantities of heavier elements so the process still has a long way to go. The core of the sun contains about 240 million trillion trillion grams of hydrogen gas as available fuel.

I have attached some more sources for your reference.

Regards

Answer 2

The exact time can't be predicted. Scientist put it around 5 to 7 billion years. Well some put it as low as one billion years.

There is also a possibility of our nearest neighboural galaxy Andromeda hitting out the sun. Its been known for years that they are moving on closer to our galaxy. This question can't be given a solid answer. The fuel for our sun is made of helium and hydrogen gasses. Its unpredictable to know the time when the sun will burst into supernova and ultimately end up in nothing!!

Answer 3

the sun is right now using the nuclear fusion reaction to produce energy
the hydrogen present in the sun is fused due to the extreme conditions and changes into helium and this produces a lot of energy

once the sun runs out of hydrogen , which is gonna take billions of years.... the sun will start utilising helium as the fuel and by fision reactions change it to carbon and energy

during this time the sun will expand into a huge mass and will engulf earth in its surface

again when the sun runs out of gas(helium) it will eventually have a lot of carbon which is heavier than hydrogen and helium

this will cause the sun to shrink back
in the process more heat will be created which would again start fussion reactions converting carbon into iron and energy

this would make the sun shrink back until a nuetrallizing force will eventually stop it from becoming a black hole

it will finally become a white dwarf

Answer 4

Hi:

in about 5 to 8 billion years from now. But no need to worry about it now. To give you a idea how long that is, if you took a year as 12 inches or 1 foot. Your life { if you live to be a hundred. } would be 8 feet 4 inches long. One million years is 189 miles and 2,080 feet, 1 billion years is 189,393 miles and 4960 feet long and 5 billion years is 949,969 miles and 3680 feet long or about 37.678727 times around the earth, it a very ,very,very long time from now. by the way the Sun will not Supernova and turn into a black hole. It will expand in size and then shink into a white drawf.

Answer 5

Sun's life-time is estimated as 10 million years! In which, 5 million years up. Sun has another 5 million years to go...

Answer 6

I agree with Kelly D. The sun is already 5 billion years old.

Answer 7

It will become big red ball called the red giant and will explode.The outer layers blast of into space and the core will smash inwards,shrinking it becomes a white dwarf.Some people think that all stars become a black hole.But actually they can be a black hole but can also be a white dwarf.Trust me I finished reading all the space books in my school library,Anyway it will take 10 billion years.(this one also comes from my studies)

Answer 8

The sun will only grow larger and larger until it gets too heavy to support itself (a supernova) and then it'll collapse and become a black hole. But that's billions upon billions of years away.

Answer 9

Scientists have calculuated that in 200 million years,
our star the "Sun" will have a super nova and the oceans will boil away.

Answer 10

Roughly 4 billion more years?
