What stage will the Sun likely enter after the main sequence stage?

Answer 1

our Sun will eventually become a red giant and a white dwarf....

Once the sun finishes fusing Hydrogen into helium it will start fusing helium. It will need more pressure to do this so it will expand. But it will cool a little as it expands. It all has to do with equilibrium. Our sun will become a red giant and expand to about half way between earth's orbit and mars' orbit. This will not happen for another 5 billion years or so supposedly since as far as we can tell stars like our sun stay in the main sequence for 10 billion years give or take and our sun is about 5 billion years old or so.

Answer 2

Answer 4

A white dwarf.
