How a proto-planet sweeps up nearby material

As shown in this picture, while they were forming in the solar nebula, the nucleii of the planets-to-be (called protoplanets) drew material to themselves from the cloud of gas and dust around them. The bigger protoplanets were able to attract even more gaseous material unto themselves. Because of its position in the solar nebula, the proto-Saturn was able to draw an enormous amount of gas unto itself.
