The most accepted view regarding the origin of the solar system is the nebular hypothesis. According to this hypothesis about 10000 to 20 thousand million years ago, there was a condensed mass of cosmic material called ylem that exploded due to the interaction of different particles forming pieces of cosmic material named Nebulae. This explosion was called Big Bang and the theory was named Big Bang Theory by Abbe Lemaitre. As these clouds condense, most of the mass of cosmic dust and gases concentrated in the center forming the sun and the surrounding cooler parts forming planets.
