What will happen to the Sun when it becomes a red giant?

When the Sun becomes a red giant, it will expand significantly, potentially engulfing the inner planets, including Earth.

How long will this transformation take?

The Sun is expected to enter the red giant phase in about 5 billion years, and this phase will last for several hundred million years.

What will happen to the Earth during this phase?

As the Sun expands, Earth will likely become uninhabitable due to extreme heat, and its surface may be scorched.

Will the Sun eventually become a white dwarf?

Yes, after the red giant phase, the Sun will shed its outer layers and leave behind a hot core, which will become a white dwarf.

Is there any way to prevent this from happening?

Unfortunately, there is no way to prevent the natural lifecycle of stars, including the Sun's transformation into a red giant.
