The Sun is one of many stars that can be found in the solar system, except that it is the biggest. It has a very huge size and covers 98 percent of the overall size of the solar system. With an average rotation of twenty five days at the equator, and thirty six days at the poles the Sun is really big.
Its diameter is 1,392,000 kilometer and has the size that is about one hundred and nine times bigger than that of Earth. The Sun is comprised of three main parts which is helium, hydrogen and other types of gasses. The Sun moves around the galactic core at an estimated speed of approximately 25,000 light years, and completes a revolution every two hundred and fifty thousand years.
The inner part of the Sun is made up of a Core, Convective and Radiative zones. The centre is known as the core and this is the place where energy is formed through a process called nuclear fusion. When the energy emanates from the core, it is moved to the nearest part which is the Radiative zone. The Radiative zone is cooler and makes up about 85 percent of the Sun's radius.
The Convective zone is next to the Radiative zone and occupies a space of up to 15 percent of the Sun's surface. The energy coming from the innermost part is moved here through stages 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 made up of photons that break out into the surface, and that is why it's called the Sun's surface. It has a thickness of about five hundred kilometer, and cannot be seen using the bare eyes. It is gassy in nature and hot.
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.
