What will your Sun become when it runs out of hydrogen fuel and has?

Answer 1

If the sun will run out of energy there would be no life on Earth, because all the plants and trees would die. So if the plants would die it would effect life cycle. Also there would be no solar light on all the planets in our solar system.

Answer 2

When the Sun runs out of hydrogen fuel and has exhausted its nuclear fusion, it will enter the next stage of its evolution as a red giant star. During this phase, it will expand and cool down, eventually shedding its outer layers to form a planetary nebula. The core that remains will contract and become a white dwarf.

Answer 3

When the sun runs out of fuel the earth and the people on it will freeze to death. But it is more likely that the sun will have a supernova which is when the sun gets to much fuel and will explode like a nuclear bomb. But still a supernova will have like a 0.0000000000001 of happening with the sun for the next 5-6,000 years. So don't worry.

Answer 4

The Sun will run out of energy at some point in its life time, in around 5 billion years or so. Stars sustain their shape by converting as much hydrogen into helium that is required to overcome the inward push of gravity. When the sun has converted most of the hydrogen it has inside of it it will swell up into a massive although cooler version of its former self, and become a red giant. Some time after this happens, when the star is finally done converting the hydrogen into helium, another spark life will come for the dying star when it begins converting helium into oxygen and other elements, it will let off a bright explosion that resembles a nova, also known as a helium flash in reference to astronomy. Since our star is a medium sized star after the helium becomes heavier elements such as oxygen and up to carbon the star will no longer be able hold itself up against gravity because the nuclear force required to sustain the star no longer has the energy to maintain itself, and it then will collapse. This is known as a Nova, where after the implosion of gravity the gases inside the star super heat by the compacting star and explode outward creating new elements that were not possible to create in the initial star.

The Earth and most of the inner planets will be engulfed by the Sun when it reaches the Red Giant phase. Jupiter will likily move in closer and wipe out Mars when this happens. All that will be left after the Red Giant phase will be Jupiter and the farther out planets, Saturn, Uranus, Neptune.

Answer 5

After 5 billion years, the sun will start to die out. When it runs out of gas it will start to shrink inside and expand on the outside. This is the process of becoming a red giant or a super red giant. All main sequence stars will become (super) red giants. Red giants form when hydrogen particles are combined to form helium particles. This process creates the energy that the star needs to resist the force of gravity that is trying to crush the star together, and causes the star to light up.

Once all of the hydrogen has been turned into helium (after about 5 to 10 billion years, depending on the size of the star) there is no longer energy keeping the star from collapsing, so gravity takes over and pulls the star into itself. But the star only collapses so far that the helium atoms can begin to combine into carbon atoms. This process now provides enough energy to stop the star from collapsing and actually pushes the outermost layers of the star out, making the star much larger than it origianlly started. The star is now a Red Giant.

The red giant would swallow up the Earth, but we would be long gone before then. (Either extinct or evacuated)

Answer 6

Yes, in fact the sun has been slowly getting brighter since it fist began fusion. It will continue to get brighter until it expels all its outer layers as a red giant and finishes as a white dwarf.

Answer 7

If Sol (our sun) were to live for another 5 billion years, then it would eventually simultaneously swell up and cool down, then contract to a glowing ember. However, in only 3 billion years, our galaxy (the Milky Way) is expected to collide with the Andromeda Galaxy, so all bets are off.

Answer 8

"Fuel" in the sense of a star like our Sun, is simply nuclear fusion. In some era far in the future, the Sun will run out of hydrogen to turn into helium through the fusion process. (The Sun turns 600 million tons of hydrogen a day into helium)

At some point, all or most of the hydrogen is used up, therefore the temperature of the Sun drops, the Sun collapses because there is not enough heat to keep it big, and the higher pressure from the collapse starts nuclear fusion with the helium that remains, creating the heavier lithium. When the helium is gone, the Sun collapses, and nuclear fusion starts with the fusion of lithium; this process continues, at each step fusing a heavier element until iron is created. Once iron is the element in the sun, there is no longer enough energy to fuse the next-heavier element, so the sun cools, collapses and explodes. This explosion (in long-ago stars) created all of the natural elements heavier than iron.

It is from these elements that you and I are made, because our solar system and about everything in it comes from material ejected by exploding stars a huge long time ago.

Meanwhile, our expended Sun collapses into an incredibly, unbelievable dense mass. A Golf-ball-sized piece of the Sun at this stage would take much heavy equipment to lift, if there were any heavy equipment left around. (Not)

But do not worry . . . you have a few billion years left to think about it.

Answer 9

The world uses roughly 80 million barrels of oil every day, and they're not making

any more of it. That means that if we keep using it, it'll eventually get used up.

It's as simple as that.

Answer 10

It will start to run on helium, but when it runs out of that, it will become a Red Giant, before collapsing under its own weight to become a White Dwarf or a Neutron Star.
