Question
Which statement about the Sun is true?AThe sun is a red giantBThe sun will become a red giantCThe sun began as a red giantDThe sun cannot become a red giant
Solution
The correct statement about the Sun is B: The sun will become a red giant.
Here's a step-by-step explanation:
- The Sun is currently a yellow dwarf star, not a red giant (so A and C are incorrect).
- In about 5 billion years, the Sun will exhaust its hydrogen fuel. It will then expand and cool to become a red giant (so B is correct).
- The Sun has enough mass to eventually become a red giant, so D is incorrect.
