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

As our star ends its life, it will swell far beyond its current size, and as it does so, it will transition into a Red Giant. During this transformation, the sun will melt our glaciers and (eventually) boil our oceans. This expanding Sun will engulf the Earth, and any life that remains along with it.

Can the Earth escape a red giant?

planet Earth will not be able to escape engulfment, despite the positive effect of solar mass-loss. In order to survive the [Sun’s expansion when it reaches the tip of the red giant branch] phase, any hypothetical planet would require a present-day minimum orbital radius of about 1.15 AU.
