Earth Doesn’t Orbit the Sun

The video explains Newton's third law of motion, emphasizing that every action has an equal and opposite reaction. This principle applies to gravity, where both objects exert forces on each other. The Earth and the sun, for example, orbit around a shared center of mass called the barycenter. This concept is crucial in understanding planetary orbits and has implications for astronomy, such as discovering exoplanets and measuring gravitational waves.
