Were the Planets Always in the Same Order?

The video explores the discovery of exoplanets and the unexpected arrangements that challenged previous notions of planet formation. It discusses the phenomenon of hot Jupiters and their migration, the role of protoplanetary disks and density waves in planet movement, and the Nice model's explanation of solar system formation. The video concludes with acknowledgments to supporters.
