The Sun is the biggest star that can be found amongst the solar system. It is so big to the point that it contains about 98 percent of the entire mass in the solar system. It rotates about 25 days around the equator, and 36 days around the poles.
It has a diameter of 1,392,000 kilometer and is 109 times the total size of Earth. The Sun is divided into three major parts, and is made up of hydrogen mass and the rest is helium and other types of gasses. The Sun orbits the galactic core approximately 25,000 light years and makes a complete revolution every 250,000 years.
The Sun's interior comprises of a Core, Radiative and Convective zones. The core is the innermost part where energy is generated through nuclear fusion. It is extremely hot and dense. The energy is transported from the hot core to the Radiative zone which is colder and covers about eighty five percent of the radius of the Sun.
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 outer visible layer is referred to as Photosphere with a temperature of six thousand degrees Celsius. This outer layer looks mottled because of the turbulence of energy eruptions at the surface.
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 next area close to the Photosphere is Chromosphere. When energy emanates from the core, it moves through the Photosphere unto the Chromosphere. There are hydrogen clouds that forms at the top of it and is referred to as Faculae.
From gathered statistics, the Sun is 4.6 billion years in activity and will continue for another 5 billion years. It also predicts, the Sun will change in its last days by fusing helium into elements that are heavier. It will become very big and overcome the Earth. Then at the expiration of a billion years, it will change into what is called white dwarf and then stay another trillion years to cool down and ultimately fade into a black dwarf.
