Keck Observatory Donor Salon: Planet Nine from Outer Space
Dr. Michael Brown
Richard and Barbara Rosenberg Professor of Planetary Astronomy
California Institute of Technology
Five years ago, Dr. Brown and his team proposed that unexpected perturbations to the most distant known objects in our solar system could be explained by the existence of an unseen giant planet well beyond Neptune, gently tugging on these objects. Dr. Brown will provide an update on his progress in the search for Planet Nine, including new discoveries which continue to strengthen the hypothesis, new analysis which refines where to look, and new observations that will — sometime soon — reveal this hidden giant.
The staff and management of the W. M. Keck Observatory wish to offer our deepest gratitude to our Astronomy Talk Series sponsors, Rob and Terry Ryan.
