Kepler's Third Law

This activity, from the Royal Observatory Greenwich, illustrates Kepler’s Third Law for our own Solar System using graphical methods, with a further look at how the same law can be used to derive information about the orbits of exoplanets around their parent stars.

The activity could be extended to allow students to research the latest confirmed data on exoplanet periods and associated stellar masses, and to plot these to find the orbital radii.
