Exploring the Outer Reaches of Our Solar System

The video explores the Oort Cloud, rogue planets, and historical discoveries like Uranus and Neptune. It delves into theories about hypothetical planets such as Vulcan and Planet X, and discusses Thea's collision with Earth. The video also examines various exoplanets, highlighting their unique characteristics and potential for life.

What is the Oort Cloud believed to be?
