The Case of the Disappearing Planet looks into the changing status of objects we call “planets.”

It not only covers Pluto, but the temporary planetary status of asteroids as well. The tally of “planets” in our Solar System has been going up and down for hundreds of years!

Have fun with this program as it features a sly, street-smart gumshoe called Skye Watcher. After a frenzied phone call from a 3rd grade teacher, she collects clues to find out what happened to Pluto.

This show is excellent as a school program that highlights the scientific method as well as understanding our Solar System.
