Kepler's Second Law

The Law of Equal Areas

The radius vector joining planet to Sun sweeps out equal areas in equal times; describes how the planet must continuously vary its speed as it follows its orbit, moving fastest at perihelion and slowest at aphelion.

Kepler's Third Law

The Law of the Harmonies

The square of the orbital period of each planet in years is proportional to the cube of the semimajor axis of the planet's orbit; gives the relationship between the planets' average distances from the Sun and their periods of revolution.
