Today we are doing a deep dive into the mysteries of the Oort Cloud, a distant and hypothetical cloud of comets that envelops our solar system. This spherical region stretches from about 2000 AU to 100,000 AU from the Sun, marking the outermost edge where the Sun's gravitational influence dominates. It's a thrilling tale of dynamics and how the solar system interacts with the galaxy!
