The Oort Cloud Believe it or Not

The video explores the Oort Cloud, a theoretical icy region surrounding the solar system, first proposed by Jan Oort in 1950. It discusses the origins of comets, their connection to the Oort Cloud, and the cloud's composition. Recent discoveries, such as Sedna and VP113, suggest the presence of a massive, unknown planet influencing these objects' orbits. The Oort Cloud remains unobserved directly but is crucial for understanding comet origins and solar system dynamics.
