Kepler's Laws of Motion

Planetary motion fundamentals

First Law (Ellipses)

Planets move in elliptical orbits with the Sun at one focus.

e = c/a

Second Law (Equal Areas)

A line joining a planet and the Sun sweeps equal areas in equal times.

dA/dt = constant

Third Law (Harmonic Law)

The square of the orbital period is proportional to the cube of the semi-major axis.

T² ∝ a³
