Solar system (सौर्य तंत्र )

                                                           Solar System 

It contains the Family of the Sun . Eight major Planets and one dwarf planet(Pluto), satellites,asteroids,meteors and comets orbit the sun to forms the solar system. 

It is sun  (Photosphere is the bright outer layer of  the sun that emits most of radiation that is visible light the temperature on outer surface of photosphere is about 6000 degree K )which provides the light and heat (Nuclear fusion) to our blue Planet due to this life is possible on Earth.

There are many theories which gives knowledge about its formation.

The Big Bang Theory indicates that the universe began abour 15 billion years ago.

Later i will provide more knowledge about Big Bang .
