it will become a red giant in 4.5 billion years
a red gaint is when a masize star is at the end of its life and its energy will run out and cause a supernova or will become so dense its own gravity will make it fall in on its self to become a black hole. so basicaly red gaint is a star dieing and a black hole; its already died.
Big stars
I would wonder what I am because the dictionary does not have the word gaint.
Yes, that's correct, for a "low mass" star like our Sun. Smaller stars, with about 8% to 80% of the Sun's mass, are red dwarfs. They follow the same sequence, but without the red giant stage.
No. The sun will become a red giant in about 5 billion years.
yes. in about five billion years the sun will become a red giant.
Our Sun will eventually become a Red Giant towards the end of its life.

The sun will become a red giant in about 5 billion years when it exhausts its core hydrogen fuel and starts burning helium in the core. This process will cause the outer layers of the sun to expand and cool, giving it a red giant appearance.
The sun will eventually exhaust its hydrogen fuel and will undergo a transformation into a red giant star. This will happen in about 5 billion years. After that, it will shed its outer layers and become a white dwarf.
It will become a red giant.
