What will become of the Sun after the red giant phase?

Answer 1

Actually the sun does not have enough mass to go supernova, after becoming a red giant its radius could actually get as big as earth's orbit, and once this happens it will lose its layers in what is called a "planetary nebula" which believe it or not has nothing to do with planets, and after this it will become a white dwarf and eventually burn out.

Answer 2

After the Red Giant phase, the Sun would enter the Supernova phase and then it would shrink to the White Dwarf which contains mainly of carbon. Don't go by what the others have said, Sun can never be a black hole, for this it should have a mass 1.5 times its present mass.

Answer 3

No need to worry about it, really. That won't happen for many more billion years. But after the red giant phase, the core of the sun would collapse into a white dwarf, a star so massive and concentrated that a teaspoon of material from the surface would weigh as much as two loaded cement trucks. After that, the core would burn out into a cinder, or a black dwarf. The sun is not a massive enough star to produce a black hole.

Answer 4

after the red giant phase it will become a blue giant after which there will be an explosion called supernova an then the sun will become a white dwarf where the even a spoon of the liquid will weight two billion kg and after that i will either become a nebula or a black hole

Answer 5

Our Sun is a normal main-sequence G2 star, one of more than 100 billion stars in our galaxy.

diameter: 1,390,000 km.
mass: 1.989 x 10^30 kg
temperature: 5800 K (surface)
15,600,000 K (core)

A star takes birth from nebula. After many many years it becomes a red supergiant and its volume increases tremendously. Then the star becomes supernova. Then there are three things a star can become after supernova:

1) It will become a BLACK HOLE.
2) It will become a NEUTRON STAR
3) It will get recycled into a NEBULA.

So when sun will be in red giant phase it will gulp down mercury and venus because of it's increase in volume and the temperature on earth will soar tremendously because of such proximity to the sun.
Then it will come in the supernova stage (it will be about 10 billion times more illuminous) for a relatively short time (couple of months or years).
Then it will become either black hole, neutron star or it will be recycled into a nebula.

Answer 6

It will become what's called a 'white dwarf star.' A white dwarf is roughly the size of Earth, made mainly of carbon, and very hot...as high as 200,000 degrees Celcius.

Forget other answers about the sun exploding. It would need at least 1.5 times more mass than it has to do that.

Answer 7

I don't get where you people get this from, sun will never even become a red giant, its small! What will happen is it will slowly burn out and collapse to a small but dense object FAR FROM BLACK HOLE. That's it! The size of the star dictates its fate and that's what sun is destined to do

Whhisssssssssssssssssh! Boooooooommmmmb!

Answer 9

someplace on the order of one billion years. If humanity remains around while this turns into an argument, then I assume we will have solved this situation. in certainty, my favourite end-of-earth state of affairs is that people will dismantle the planet for uncooked factors to construct area colonies - that can genuinely be placed on the main gentle distance from the sunlight, regardless of that could be. desire that enables!

Answer 10

When the sun will run out of fuel it will shrink to become white drawf.
