Kepler's Second Law

The shaded regions have equal areas. It takes equal times for $m$ to go from $A$ to $B$, from $C$ to $D$, and from $E$ to $F$. The mass $m$ moves fastest when it is closest to $M$. Kepler's second law was originally devised for planets orbiting the Sun, but it has broader validity.
