Detailed explanation-1: -Fortunately, the Sun’s supply of hydrogen is so great that it will continue to shine for another five billion years.
Detailed explanation-2: -A: Roughly 5 billion years from now, the Sun will exhaust the hydrogen fuel in its core and start burning helium, forcing its transition into a red giant star. During this shift, its atmosphere will expand out to somewhere around 1 astronomical unit-the current average Earth-Sun distance.
Detailed explanation-3: -When our Sun approaches its red giant phase some 6 billion years from now, it will run out of fuel in its core. As hydrogen fusion slows, the core once again begins to contract.
Detailed explanation-4: -About 7.6 billion years from now, the sun will reach its maximum size as a red giant: its surface will extend beyond Earth’s orbit today by 20 percent and will shine 3, 000 times brighter. In its final stage, the sun will collapse into a white dwarf.
