Kepler's Second Law
A line segment joining a planet and the Sun sweeps out equal areas during equal intervals of time. This means planets move faster when closer to the Sun (perihelion) and slower when farther away (aphelion).
The colored sectors demonstrate this principle - despite different shapes, they represent equal areas swept in equal time periods.
