The video explores why the moon orbits Earth instead of the sun, despite the sun exerting more gravitational force on the moon. It explains the apparent size similarity of the moon and sun due to distance and size ratios. The sun's dominance in the solar system is highlighted, holding most of the system's mass. The concept of the Hill sphere is introduced, explaining how Earth's gravity dominates within this region, allowing the moon to orbit Earth.
