      Roughly 1.1 Billion years from now it will enter the Red Giant Phase. After that its a little unclear – we know it will eventually run out of fuel and become a white dwarf but we are not sure exactly when. Best guesses put it around 2.3 to 5 billion years from now.

      So either a Red Giant or a White Dwarf 🙂
