text: The core of terrestrial planets consists mainly of iron, wrapped in a silicate mantle.
text: The core consists of a molten (liquid) outer core primarily consisting of iron but with substantial percentages of materials such as sulfur and silicon which lower its melting temperature, and a solid inner core which is almost certainly a crystalline mixture of iron and nickel similar to iron meteorites.
text: For an object like the Earth (or Venus, since it appears to be similar to the Earth, as already discussed) we have an outer rocky mantle consisting of various forms of ferromagnesian silicates, depending upon the pressure compressing the material at various depths, and an overall density 20 to 25% less than the actual density of the Earth; and an inner primarily metallic core consisting mostly of iron, but with lesser amounts of nickel and in the outer core additional materials, which has an overall density two to three times that of the Earth.
text: Saturn’s core consists of iron, nickel, silicon, and oxygen compounds, all surrounded by a thick layer of metallic hydrogen.
