Question

what will happen the sun exists over a day​

Answer 1

Answer:

• Our star is powered by nuclear fusion, and it turns hydrogen into helium in a process that converts mass into energy. Once the fuel supply is gone, the sun will start growing dramatically. Its outer layers will expand until they engulf much of the solar system, as it becomes what astronomers call a red giant.
• For about a billion years, the sun will burn as a red giant. Then, the hydrogen in that outer core will deplete, leaving an abundance of helium. That element will then fuse into heavier elements, like oxygen and carbon, in reactions that don't emit as much energy.
• It would be complete and utt er ch aos in our solar system. Light, on the other hand, is not inst antaneous: It travels at approximately 671 million miles per hour and takes roughly 8 minutes to reach Earth. Therefore, we would still see the sun in our sky eight minutes after it was gone.
