Unseen Objects in Our Solar System

Penn Science Cafe

Masao Sako will discuss his research on searching for new objects in the solar system. He will describe efforts to discover objects beyond the orbit of Neptune, some of which contain valuable information about the complicated dynamical history of the system. Dr. Sako will also discuss why astronomers think that there is a massive previously-unseen planet out there, called Planet Nine, and how it might be found.

Expert faculty from the University of Pennsylvania shed light on their research at the Penn Science Café. It's an evening of engaging, stimulating conversation, with a Q&A session following each talk.

Presented by Penn Arts and Sciences in partnership with the Office of University Communications, Penn Café events are free and open to the public, but RSVPs are encouraged. For more information or directions, contact Gina Bryan at 215-898-8721 or email at
