Thermonuclear fusion of hydrogen occurs during the red giant phase. Helium to carbon fusion, or dredge up, also occurs at this time.
When aÊstar completes it's Red Giant phase they become White Dwarfs. The Red Giant phase of stars takes about a billion years.
It probably wont hit Mars at the Red Giant phase but Mars will get VERY hot.
Near the death of a star, the star swells and this phase is known as red giant phase.
A star that is in it's teenage years(medium star) isn't a red giant until it's last years.

a red giant
The biggest star - VY Canis Majoris IS in a red supergiant phase and will explode as a massive supernova.
the red giant phase is about the end of a stars life. it will last for about one million years.
Our Sun is a stable star but, that's not the way things will always be. In about 6.4 billion years from now the Sun's Hydrogen fuel supply will run low. Then the Sun will swell up and will become about 100,000,000 miles across during it's Red Giant phase. It will become about the size of were earths orbit is and devour it. Mercury, Venus, and Earth will have been engulfed in the Sun. The outer planets will live on. After the red giant phase, the sun will explode in a supernova and all that will be left is the core. The outer planets warmed up during the red giant phase and will continue to orbit the white dwarf core.
No. The Sun is a main-sequence star. It will not be a red giant for another 5 billion years.(see related link for an image of what the Sun would look like in its red giant phase
A star that is in it's teenage years(medium star) isn't a red giant until it's last years.
Yes, in around 5 billion years the sun will enter a red giant phase. In this phase the sun will expand greatly and the earth will be destroyed. After the red giant phase the sun will be reduced to its core and begin to cool down. This stage is the white dwarf phase. The sun will not go supernova as it does not have the necessary mass.
we will be in big poopy
