The Formation of the Solar System and the Structure of the Sun

The video explains the formation and structure of the solar system, starting with the sun and its characteristics. It covers the formation of planets from a protoplanetary disk, the dynamic history of the solar system, and the order of planets. The video also highlights the processes of fusion and accretion that led to the solar system's formation, emphasizing that all elements on Earth originated from stars.
