7.2 Composition and Structure of Planets
When we look at the internal structure of each of the terrestrial planets, we find that the densest metals are in a central core, with the lighter silicates near the surface. ... speaking, the farther a planet or moon is from the Sun, the cooler its surface. The planets are heated by the radiant energy of the Sun, which gets weaker with the ...
16.3 The Solar Interior: Theory
Describe the structure of the solar interior; ... The outward flow of energy through a star robs it of its internal heat, and the star would cool down if that energy were not replaced. Similarly, a hot iron begins to cool as soon as it is unplugged from its source of electric energy. Therefore, a source of fresh energy must exist within each star.

6. Evolution and internal structure of the Sun. I.
supply of gravitatio nal energy, thus the star will contract a bit. As the core contracts it heats up a bit, the pressure increases, and the nuclear energy generation rate increases until it matches the energy required by the luminosity. Similarly, if the star overproduces ene rgy in the core the excess energy will heat the
Internal Structure of the Gas Giant Planets
Carefully applying simple physical principles, scientists have hypothesized the internal structures of the giant planets. They know the planets'' chemical composition and overall density. They apply the idea of differentiation — the tendency for heavier elements and compounds to sink to the center of a planet.
