What is sun? Complete information about its history and Future?
About:
The Sun is a star and is the center of the Solar System. Here is some information about its history and future:
History:
The Sun formed approximately 4.6 billion years ago from a cloud of gas and dust called a solar nebula.
As gravity caused the nebula to collapse, the center became denser and hotter, eventually leading to the ignition of nuclear fusion in the core of the Sun.
The Sun's energy is produced by the fusion of hydrogen atoms into helium, a process that releases a tremendous amount of energy in the form of heat and light.
The Sun is estimated to have about 5 billion years left before it exhausts its hydrogen fuel and begins to evolve into a red giant star.
Future
As the Sun runs out of hydrogen fuel, its core will shrink and heat up, causing the outer layers to expand and cool, leading to the Sun's transformation into a red giant star.
During this phase, the Sun will expand beyond its current size, possibly swallowing up Mercury, Venus, and even Earth.
After the red giant phase, the outer layers of the Sun will be ejected into space, forming a planetary nebula, while the remaining core will evolve into a small, dense object called a white dwarf.
The Sun's white dwarf phase will last for billions of years, eventually cooling down and becoming a cold, dark object known as a black dwarf.
In summary, the Sun is a star that formed from a solar nebula 4.6 billion years ago and is currently in the middle of its hydrogen-burning phase. In the future, the Sun will evolve into a red giant star, expand beyond its current size, and eventually become a white dwarf and later a black dwarf.
