CrashCourse

In which John Green, Hank Green, and Emily Graslie teach you about our Sun and the formation of the planets. We're going to focus on the formation and development of the Earth because that's where people live. You'll learn about the Solar nebula, the birth of the sun, the formation of planets, and how the Earth and the rest of the solar system developed over the last 4.567 billion years.
