can and will the sun go out and if so than when?

Question

well see the sun is just a big star and when a star goes out it creates a black hole and a pull in the universe and pulls anything around it in
including light . The sun is the biggest star in our solar system so what could happen if it did go out ? what would happen to the planets? would they get pulled in ?

Answer 1

The Sun, in 4.5 billion years supposedly, WILL start to swell. It will get bigger, and en-gulp Mercury and Venus. The atmosphere will evaporate, water will melt, and life will be gone. The sun will swell enough to devour the earth, then shrink, grow, Turn into a planetary nebula, then shrink, for the last time, into a white dwarf. Then In a few billion years, cool down to a black dwarf.

The reason the sun expands, In case you want to know, Is because of its fuel supply. The energy from the sun comes from nuclear fusion of Helium. When the helium supply runs out, The sun has to fuse hydrogen, therefore making the sun swell. The sun then will Shrink, once its helium supply is restored, grow again, then cast out a planetary nebula (For what a planetary nebula looks like, Look up the ring nebula) then it wont have enough hydrogen to grow back to the normal size...and become a white dwarf. Eventually, it will cool into a black dwarf and die. No, it will not go become a black hole.

Answer 2

The sun will go out in a few billion years, but it will not become a black hole because it is too small. After a red giant phase, which will fry the Earth about 5 billion years in the future, the Sun will become a white dwarf, cooling forever but not really getting totally cold for trillions of years.

By the way, black holes do not pull everything in. If the Sun were somehow compressed enough to be a black hole, the Earth would continue to orbit it as it does now. The Sun's gravity would not change at all. It would only be that if the Sun was that small, 10 or 20 miles across, then it would be possible to get close enough for the escape velocity to be higher than the speed of light. But the diameter of the volume where gravity would be that strong is far smaller than the Sun is today, so none of the planets would be pulled in or even feel any change in the Sun's gravity at all.

Answer 3

Fresh Prince has it completely correct.

Our Sun will never become a black hole - only stars that start out with way more than 10 times the mass of our Sun eventually become black holes.

Our Sun will never go supernova, either. Only stars with at least 8 times the mass of our Sun go supernova.

Our Sun is the only star in our solar system. Compared to other stars in our galaxy, it is average, maybe even on the small side.

Oh, and black holes don't suck.

Answer 4

Not all sun's when they go out create a black hole. Some do the giant red star and and some the white dwarf. There is something that helps to create a black hole beside the collapsing. It depends on the fuel it has left. I don't find any that are not i9n the center of a galaxies. Near the center it is awful to see a sun and its solar system just inhaled the force is out of our greatest imagination. It creates such a gravity well that as it gravity force extends for light years. If the sun goes out everything will be frozen in a minute.

Answer 5

Not every stars create a black hole when they die. Smaller stars, like our sun, will eventually die out and become a white dwarf. Larger stars will go supernova and create a neutron star, or even a pulsar which is the remnants of the star with a tremendous angular velocity. The most massive of stars become black holes when they go supernova.
The sun is the only star is our solar system, and it will die out in about 5 billion years, so we have nothing to worry about. But when it goes out, first it swells up to a red giant consuming the 4 inner planets, then after it runs out of "fuel" it will shrink in size and become a white dwarf. The larger stars that that become neutron stars, pulsars, and black wholes actually explode in the red giant stage instead of shrinking down.

Answer 6

about 4.5 billion years from now, and the sun is the only star in the solar system. The planets and asteroids make up the other heavenly bodies.... The Supernova will leave the earth a burnt crisp. The oceans will have been evaporated and we'll be just a huge mass of rock.... some destiny, huh?

Answer 7

Most scientists peg the period of the sun's destruction at 5 billion years from now.The sun will go out in a brilliant flash and become a dead star as many others have done in the universe. The earth and other planets of our solar system will also be leaving behind a magnificent atomic shroud of varied colours as a result of a cataclysmic event.

Answer 8

The sun is the ONLY star in our solar system ! And in time our sun will die like all stars do. And no it won't create a black hole ! It will do one of two things. Become a red giant and fry everything in our system. Or it will become a super nova and explode. You've confused our galaxy with our solar system. They are not the same thing...They believe our sun will die in a couple of billion years from now.

Answer 9

well for ti to bevome a balck hole it has to become a red giant. then super nova. If it becomes a red giant it will engulfe the solar system we know out to about jupiter. and when it super novas (explodes) it will distroy all planets with in a certain distance. To become a black hole the red giant needs to be of a certain size and weight. It's rare.

and as for time .... maybe million + years?

Answer 10

I will go out but it will be a very VERY long time before it happens. Long before it goes out, it will expand in size many times, eventually engulfing the orbit of the Earth. I sure hope mankind finds a new home before then, assuming we don't kill each other off first.
