The Sun Today and as a Giant

Description
The Sun Today and as a Giant
(a) In about 5 billion years, when the Sun expands to become a giant, its diameter will increase a hundredfold from what it is
now, while its core becomes more compact. Today, the Sun’s energy is produced in a hydrogen-fusing core whose diameter
is about 200,000 km. When the Sun becomes a giant, it will draw its energy from a hydrogen-fusing shell that surrounds a
compact helium-rich core. The helium core will have a diameter of only 30,000 km. The Sun’s diameter will be about
100 times larger, and it will be about 2000 times more luminous as a giant than it is today
