These winds , which are up of atomic particles being outward from the Sun , slowly pushed the remaining gas and dust out of the Solar System . With no more gas or dust , the planets , minor planets , moons , comets , and asteroids stopped growing . You may have noticed that the four inner planets are much smaller than the four outer planets . Why is that ? Because the inner planets are much closer to the Sun , they are located where the solar winds are stronger . As a result , the dust and gas from the inner Solar System was away much more quickly than it was from the outer Solar System . This the planets of the inner Solar System less time to grow . Another important difference is that the outer planets are largely of gas and water , while the inner planets are up almost entirely of rock and dust . This is also a result of the solar winds . As the outer planets larger , their gravity time to accumulate massive amounts of gas , water , as well as dust .
