Your parents and grandparents were most likely taught that our planetary system ended at Pluto, but our discovery of Kuiper Belt in 1992 changed all that. The Kuiper Belt is a large population of icy bodies left over from the formation of the planets — the unused material, so to speak. The discovery changed how we viewed our solar system, how we viewed other solar systems, and even clarified the nature of Pluto. This talk will describe the discovery process. I would like the talk to be interactive, so I will ask participants how they themselves would solve various problems if they were looking for the edge of the planetary system.
