According to the nebular theory, the solar system began to form about 4.6 billion from a giant rotating cloud of gas and dust, called a solar nebula.
What Happens Next?
.An unknown event, such as the shock wave caused by a supernova or the movement of a passing star, caused the cloud to begin to collapse under its own gravity, and the giant gas cloud began to contract.
Funny You Should Ask!!
Gravity was central to the development of the solar system. Gravity is the force of attraction that occurs between masses and draws objects toward each other.The strength of an object’s gravitational pull on another object is controlled by the mass of each object and the distance between them. The greater the masses and the closer together they are, the greater the gravitational pull
