The recent suggestion of evidence of a massive ninth planet in the outer solar system has set off a worldwide search to find this latest member of our planetary family. Mike Brown, professor of planetary astronomy at California Institute of Technology and discoverer of several Kuiper Belt objects, will explore the evidence of Planet Nine and the prospects for the search now underway.
The Exploring Space lectures are made possible by the generous support of Aerojet Rocketdyne and United Launch Alliance.
