The general consensus of scientists is that it formed through a process called accretion. It is probable that it began with gravity pulling together gases in a cloud or nebula to form the Sun, and some "pockets" of material coales...

Scientists believe that the solar system was formed when a cloud of gas and dust in space was disturbed, maybe by the explosion of a nearby star (called a supernova). This explosion made waves in space which squeezed the cloud of gas and dust.

Scientists believe that the solar system was for med when a cloud of gas and dust in space was disturbed, maybe by the supernova of a nearby star. Shock waves from the explosion compressed the cloud of gas and dust. Icy matter settled in the outer regions of the disk, where the giant planets like Jupiter formed.
