Why Are the Inner and Outer Planets Different?

The video explains the order of planets in our solar system, using a mnemonic to remember them. It delves into the formation of the solar system, starting with a protostar and a protoplanetary disk. The inner planets formed from metals and rocks, while the outer planets formed beyond the frost line, where ices could condense. The video also discusses the Kuiper Belt and the evolution of the solar system, concluding with a call to support SciShow Space.
