The Hunt for Planet Nine

Scientists have proposed that there is a giant planet lurking beyond Pluto, a Neptune-size world orbiting the sun about 20 times the distance of Neptune’s orbit, but so massive that it may have tipped the entire solar system a few degrees sideways. A race is on to discover this as yet unseen Planet Nine using classical astronomy and new computational techniques. In this presentation, Michael Medford will discuss why scientists believe that Planet Nine exists, how the search is being conducted, what has been learned so far in the quest to answer the question of whether Planet Nine exists or not.
