What would eventually be the fate of the sun?

What would eventually be the fate of the sun?

Once all the helium disappears, the forces of gravity will take over, and the sun will shrink into a white dwarf. All the outer material will dissipate, leaving behind a planetary nebula. “When a star dies, it ejects a mass of gas and dust — known as its envelope — into space.

What is the likely fate of our own star the sun?

The sun will shrink down to become a dying ember of a star, known as a white dwarf, only a little larger than Earth. Artist’s concept of our sun as a white dwarf. Image via Chandra X-ray Observatory.

What is the sun’s ultimate fate?

All stars die, and eventually — in about 5 billion years — our sun will, too. Once its supply of hydrogen is exhausted, the final, dramatic stages of its life will unfold, as our host star expands to become a red giant and then tears its body to pieces to condense into a white dwarf.

What is the fate of our sun when it dies?

But for the sun, death is not the end. While about half its mass will flood out, the rest will crush together at the very center of the planetary nebula. This will turn into a tiny, bright, ultra-dense ember of the sun’s core, no larger than the Earth. This kind of smoldering remnant is called a white dwarf star.

What is the energy source for all stars?

Nuclear Fusion Many stars produce much more energy than the Sun. The energy source for all stars is nuclear fusion. Stars are made mostly of hydrogen and helium, which are packed so densely in a star that in the star’s center the pressure is great enough to initiate nuclear fusion reactions.

What will happen to the Sun’s habitable zone in the future?

What will happen to the Sun’s habitable zone in the future? It will move outward.

What is the most likely fate of our sun and that of the earth?

Earth exists thanks to our sun, having formed in orbit around it from a huge cloud of gas and dust in space, 4.5 billion years ago. Likewise, the sun will ruin Earth for living things, some 5 billion years from now. As the sun evolves, it’ll expand to become a red giant star and fry our planet to a cinder.

What’s the ultimate fate of the Sun?

The ultimate fate of our sun is to: become a white dwarf that will slowly cool with time After a massive star supernova explosion, the remains of the stellar core:

How will the Sun end its life?

Once our own Sun has consumed all the hydrogen fuel in its core, it too will reach the end of its life. Astronomers estimate this to be a short 7 billion years from now. For a few million years, it will expand into a red giant, puffing away its outer layers.

When the Sun dies what will happen?

Even if the expanding dying sun doesn’t reach Earth, the sun’s high temperatures will completely burn the planet. When the sun becomes empty, it will become unstable and begin to pulse. Each pulse will remove more and more of the sun’s mass until all that is left is the cooler core. At this point, the sun will be a white dwarf.

Will the Sun eventually explode?

No, the Sun will not explode. To explode indicates that the internal forces will eventually overcome gravity and violently tear the Sun apart. This is not the fate in store for the Sun. As Clark described, the Sun will eventually start to burn helium to produce Carbon. However, that is as far as it will go.
