Complete Education Regarding The Sun
by Haywood Hunter
The Sun is a star located at the center of the solar system. It is the most outstanding and largest feature seen and contains about ninety eight percent of the total solar systems mass. Its rotation varies approximately at twenty five days at the equator and thirty six days at the poles.
The Sun's diameter is about one million three hundred and ninety two thousand km, and about one hundred and nine times the size of Earth put together. A three quarter of it is comprised of hydrogen mass with the remaining components being helium and other gases. Studies show that it orbits about twenty five thousand light years from the galactic core and completes a revolution once in every two hundred and fifty million years.
Inside the Sun, there are 3 basic elements which are a Core, Radiative and Convective zones. The centre is called the core, and a great energy is made here through a process that is referred to as nuclear fusion. This energy is then transferred to the closest zone called the Radiative zone. The Radiative zone makes up eighty five percent of the Sun's radius.
The Convective zone is the part just below the Sun's surface and covers about fifteen percent of the surface of the Sun. Energy is transported by a bulk motion of gas, and this is a process called convection.
The Photosphere which is the visible layer has a temperature of approximately 6,000 degrees Celsius. It always seems molted as a result of the turbulence created by energy eruptions.
The photosphere is referred to as the Sun's surface because it has photons that are able to escape into space. It is around 500 km thick, and extremely heated up, gaseous, and not something that can be seen through with ordinary eye alone.
The area above the photosphere is called the Chromosphere. Solar energy passes through the Chromosphere from the core. The bright luminous hydrogen clouds are called Faculae and form sunspots above.
According to studies, the Sun has been very active for about 4.6 billion years and will be here for another 5 billion years. The studies also show that the Sun will transform in its last days and fuse helium into elements that are heavier. It will grow big to the point where it will overcome the Earth. After that, when a billion years is elapsed, it will collapse into a white dwarf and may endure an extra trillion years to become cool and finally fade into what is known as a black dwarf.
