Where Does the Solar System End?

William B. McKinnon, Ph.D.

Department of Earth and Planetary Sciences

Moderated by: Cynthia Wichelman, M.D.

Fortune favors the prepared mind.
Louis Pasteur, 1854

Fortune certainly favored William Herschel, who quickly recognized the “comet” he saw was actually a planet that eventually became known as Uranus; and likewise the German astronomers whose star chart allowed them to quickly locate the new planet predicted by Le Verrier (Neptune). The discovery of Pluto was more a matter of photographic technology and sheer Midwestern grit. And it is technology and determination that, over the past 25 years, have more fully revealed the trans-Neptunian Kuiper belt, but every time we seem to have detected the limit of the Solar System, the goal posts move. Is there a limit? Are any of the new worlds we keep finding “planets”? Will we ever actually see the Oort cloud?
