What will happen to the planets when the Sun becomes a red giant?
The Sun will expand and heat up, forcing its current habitable zone, which now encompasses Earth, outward. It will engulf Mercury, Venus, and likely Earth. Any surviving earthlings will have long since fled the brightening Sun. The atmosphere of Jupiter and Saturn will erode under the radiation from the Sun. Some gas exoplanets will survive.

Will Earth survive when the sun becomes a red giant? – Phys.org
The sun will become a red giant in 7.59 billion years, when it will lose most of its hydrogen and helium and expand to a huge size. This will cause the inner planets to be swallowed by the sun, including Earth, which will be scorched by the intense heat. The researchers calculated that the sun will be 256 times its current size and only 67 percent of its current mass at this point.
