How did the sun inner and outer planets show up in this model?

In the model of the solar system, the Sun is positioned at the center, serving as the primary source of gravity and energy. The inner planets, composed mainly of rock and metal, are depicted as smaller and closer to the Sun, highlighting their higher density and warmer temperatures. In contrast, the outer planets, which are larger and primarily gas giants, are shown farther away, reflecting their lower density and cooler atmospheres. This arrangement illustrates the distinct characteristics and formation processes of the inner and outer planets in relation to the Sun.
