Exploring the Oort Cloud: What Lies Beyond Our Solar System

The video explores the Oort Cloud, a theoretical region beyond the Kuiper Belt, believed to be the source of icy objects and comets. Named after astronomer Jan Oort, it is thought to be a spherical shell of debris from the solar system's formation. The Oort Cloud is influenced by gravitational forces and interstellar events, which can send comets towards the sun. Estimated to be 2,000 astronomical units from the sun, it may contain around 2 trillion objects. The discovery of Sedna suggests it could be part of the inner Oort Cloud. Future space missions may confirm its existence.
