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.

About the Exploring Space Lecture Series: Giants of the Solar System and Beyond

Giant planets in our solar system lie beyond the asteroid belt. The Juno spacecraft has recently arrived at the largest, Jupiter.  Cassini will soon end its mission at Saturn.  Farther afield, tantalizing clues suggest the existence of Planet Nine, a rocky world ten times the mass of Earth.  And immense worlds called Super-Earths and Hot Jupiters orbit stars other than our own.  Join four distinguished speakers as they explore the unimaginably huge, stunningly beautiful, and sometimes bizarre giant worlds. Learn more. 

The Exploring Space lectures are made possible by the generous support of Aerojet Rocketdyne and United Launch Alliance.
