Our Definition For “Moon” Is Broken (Collab. w/ MinutePhysics)

The video explores the historical and current understanding of what constitutes a moon. Initially, humans believed all celestial bodies orbited Earth, but this view evolved as we discovered other objects orbiting the sun. The term 'moon' now generally refers to natural satellites of planets. However, defining a moon is complex due to the variety of shapes, sizes, and behaviors of celestial bodies. The video argues for a more precise definition, considering factors like size, orbit, and visibility. It highlights the challenges in classifying moons, especially with technological advances revealing smaller celestial bodies.
