Learn about the precession of perihelion phenomenon in planetary motion through this 31-minute lecture that explores how the closest point of a planet's orbit to the Sun gradually shifts over time. Examine the classical mechanics behind orbital precession, understand the factors that contribute to this astronomical phenomenon including gravitational perturbations from other celestial bodies, and discover how Einstein's theory of general relativity provides additional corrections to the classical predictions. Analyze specific examples of perihelion precession in our solar system, with particular attention to Mercury's orbit which provided crucial evidence for Einstein's theory, and explore the mathematical frameworks used to calculate and predict these orbital changes.
