Scientists believe that the solar system should be a product of a big supernova. According to the new research, scientists claim that the formation of the solar system started 4.6 million years ago.

According to Space, scientists are not sure of the exact nature of the process of formation and evolution of the solar system. Observation of new solar systems and computer simulations allowed them to peek into the process of creation of the solar system. The earlier model named Nebular hypothesis was the first model to describe the process of the formation and evolution of the solar system.

In the process of formation of the solar system, the solar nebula was created after the supernova. The waves from supernova trigger the creation of the sun, and gravity of sun has attracted other particles and matters towards it. These particles and other matters created a disk form which circulates around the sun. This process of creation of big stars attracting the other matters towards it and they started circulating the sun due to the gravitational force called solar nebula.

NASA cited that as all dust started to settle down and the disk got thinner, the particles started to stick together and form clumps. These clumps of particles got bigger by sticking to other clumps and formed various planets and moons causing the formation of a solar system. The various planets had taken birth from the cloud of dust, gas and other particle included in the solar nebula.

The current solar system which is seen today is very different from the initially created solar system. After the initial creation of the solar system, it is believed that there should be the existence of 50 to 100 moon or mars sized planet. These objects should have been collided due to the gravitational force and other new planets have been created.
