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.
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.
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.
Staying next to the Radiative zone is the Convective zone. The space it occupies makes up 15 percent of the entire surface of the Sun. Through a process called convection, energy rises from the core all the way to this zone.
The layer of the Sun that can be seen outside is called the photosphere and its temperature is six thousand degrees Celsius. It looks like it is always molting because of the unrest created as a result of internal eruptions.
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.
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.
