Why Planets Orbit Faster When They Are Closer to the Sun

Why planets orbit faster when closer to the Sun: Kepler's second law requires them to sweep equal areas in equal times, so speed increases at perihelion and decreases at aphelion. This speed-distance relationship emerges from orbital geometry and Newton's law of gravitation, with Mercury showing the most dramatic variation in the solar system.
