Detailed explanation-1: -In approximately five billion years, our own sun will transition to the red giant phase. When it expands, its outer layers will consume Mercury and Venus and also reach Earth. Scientists are still debating whether or not our planet will be engulfed, or whether it will orbit dangerously close to the red giant sun.
Detailed explanation-2: -Once the Red Giant phase is complete the Sun will evolve into a White Dwarf, during which it will lose about half of its mass. As the Sun loses mass the radii of the orbits of the remaining planets, from Jupiter outward, will increase, but still remain in orbit around a now lighter Sun.
Detailed explanation-3: -The Sun’s hydrogen core will eventually be exhausted, after the Sun is 10 bil-lion years old. The Sun will be-come, in turn, a red giant, a white dwarf, and a black dwarf. layers will expand for the next 1.5 billion years until the Sun is 3 times its present size.
