Adding thumbtacks for Saturn’s orbit

Adding thumbtacks for Jupiter’s orbit

Under construction–the inner four planets; notice the strings hanging from the sun to give proper radii.

The four rocky planets; notice the “A” in “Asteroid belt” at the top, center of the photo.

Our final whiteboard showing approximate orbits and lab tables.

First step in the construction was to place dots at the location of each planet every week/month
