Question

how can you determine that a star is about to turn into a red giant

Answer 1

⊕ANSWER⊕

• A red giant star is a dying star in the last stages of stellar evolution.

• In only a few billion years, our own sun will turn into a red giant star, expand and engulf the inner planets, possibly even Earth.

• This increased core temperature and pressure causes helium to fuse into carbon via the triple alpha process.

• This increased radiation pressure pushes matter outwards, thus expanding the star.

• As the star expands its surface cools and becomes redder - a red giant is formed.

Answer 2

Answer:

Answer:In approximately 5 billion years, the sun will begin the helium-burning process, turning into a red giant star. When it expands, its outer layers will consume Mercury and Venus, and reach Earth.
