The fiery sun

The fiery sun

The sun is  a huge mass of gas made up of hydrogen and helium. Though a star, it is 113 time digger than the earth. The sun has about 330,000 times the mass of the earth. The sun gives off its light and heat in all directions. Only tiny fractions of its rays reach the earth. But these tiny fractions of rays are sufficient to provide energy to all living beings on the earth. Some of the rays are quite harmful, but the magnetic field covering the earth protects us by not letting these rays, to enter our planet.

 Inside the sun

The energy produced inside the core of the Sun takes approximately 10 million years to come to the surface of the Sun, after passing through several layers.

A part from heat and light, the Sun generates gamma rays, ultraviolet radiation as well as infrared and radio waves. The temperature at the core of the Sun is over 15,000,000c .

What is Photosphere and Corona ?

Photosphere is the outer surface of the Sun. It is a 500 kilometre thick layer of gas.

The heat inside the sun generally erupts on the surface in patches at frequent intervals known as granules. The corona is the outer atmosphere of the Sun. We can view corona during total solar eclipse. The temperature of corona is 500,000c corona sends out a stream of particles known as solar wind at solar wind at frequent intervals.
