Once its knowed the value for the Astronomical Unity we can find the size of the orbit of any planet in the Solar System using the Kepler's Third Law. This law relate the orbital period of a planet, in years, with the axis of its orbit, in Astronomical Units.

In the attachments you can find an activity guide for the students and a teacher's guide.
