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 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.
Next to the Photosphere is a region called the Chromosphere. The energy emanating from the core, passes through all the way to the Chromosphere. The hydrogen clouds forming at the top is called Faculae and makes sunspot directly at the top.
Studies show that the Sun has been active for the past 4.6 billion years and will keep burning for another five billion years or more. It also indicates that the Sun will start fusing helium at the end of its life into heavier elements and start to swell and grow so large to swallow the Earth. It will collapse after a billion years to what is known as white dwarf, and may take up to a trillion years to completely cool off and fade into what is called a black dwarf.
