It will eventually. In about 5 billion years the sun will deplete the hydrogen at its core. Afterward it will continue to alternate between fusing helium in the core and fusing hydrogen in a shell around the core before it finally dies.

The sun does not use oxygen in a chemical burn, it produces energy by nuclear fusion which converts hydrogen into helium with a very large release of energy. This is similar to what happens in a H-bomb. The sun will eventually run out of fuel and die, but that is many millions of years off.

The "fire" in the sun is not really fire. The sun is made of superheated plasma, which at fir glance, seems to resemble fire. While fire is driven by combustion, the sun is powered by a process called nuclear fusion. At the sun's core, the enormous heat and pressure causes hydrogen atoms to fuse together into helium atoms, releasing energy. The process of fusing hydrogen releases millions of times more energy than combustion does for the same amount of fuel.

Will the sun ever run out of energy and or explode?

The sun will eventually run out hydrogen at its core, which is the source of energy, so it will die, but it will not explode.


Why will the sun burn out?

The sun generates energy by fusing hydrogen into helium. Eventually it will run out of hydrogen. However, this won't happen for several billion years.


When does hydrogen-helium fusion and helium-carbon fusion occur in stars like our sun?

When hydrogen stocks run out


Is it possible for the sun to become exhausted?

The expectation is that some day in the (to us) far future, most of the hydrogen in the sun will have been converted to helium (and higher weight atoms). At that point, the sun will be "exhausted" since the energy of the sun comes primarily from the fusion of the hydrogen - when there is no hydrogen left to fuse, the sun will have run out of "fuel".


How is a sun like star able to being helium fusion?

Hydrogen stalks run out


Why won't the sun run out of energy?

It will, but not for several billion years. The sun is powered by nuclear fusion, converting hydrogen into helium. The sheer mass of the hydrogen is enough to sustain it for quite some time.


When will the sun run out of hydrogen source?

In about 6 billion years. Wear a jacket, it will be cold that day :)


Where is hydrogen found on the sun?

The Sun is about 70% hydrogen.


How many hydrogen atoms does the sun have?

Three-quarters of the Sun's mass is hydrogen. How many hydrogen atoms are in the Sun?


Why is the sun going to run out?

it will go out because EVERY star has a life like humans but dont worry from 2010 in 5 billion years


Will the sun explode?

No. The sun will run out of hydrogen in about 5 billion years, after which it will become a red giant. It will later lose its outer layers and die, but it will not explode.


Is hydrogen affected by the sun?

no hydrogen is not affected by the sun because hydrogen can be combined with helium it creates a fuel source but it is not affected by hydrogen by it self so no hydrogen is not affected by the sun
