Question

A. What will the sun turn into when it runs out of fuel for fusion? (5 points)

Answer 1

The sun will heat up and expand into a Red Giant star, then heat up to an extreme temperature, explode, and compact into an even hotter white dwarf star.

Step-by-step explanation:

when our Sun runs out of hydrogen fuel, it will expand to become a red giant, puff off its outer layers, and then settle down as a compact white dwarf star, then slowly cooling down for trillions of years.

Answer 2

White dwarf

Step-by-step explanation:

Sun is a G-2 average mass star. It is 4.56 billion years old and would live for another 5 billion years. When the Sun would run out off fuel, its outer layers would expand and it will form a red giant star. The outer layers would eventually blow off into space and the remaining core would become a white dwarf. White dwarf is an electron degenerate star.
