The three primary substances that make up the planets are gases, metals, and ices. Gaseous planets, like Jupiter and Saturn, are predominantly composed of hydrogen and helium, while terrestrial planets like Earth and Mars are mainly made up of silicate rocks and metals. Ices, such as water, ammonia, and methane, are also significant in the composition of some outer planets and their moons. The specific proportions of these substances vary, leading to the diversity of planetary types in our solar system.
