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 called the Sun's surface because it consists of photons that do break out into space. The thickness is about five hundred km and not an everyday thing that can be seen using the eyes only. It is severely hot and very gaseous.
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.
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.
