  • Penn Cafe Event: "Unseen Objects in Our Solar System"

    World Cafe Live 3025 Walnut Street

    Masao Sako (U of Penn)

    Masao Sako will discuss his research on searching for new orbits 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.
