BOONE, NC (March 2, 2017) By Ellen Gwin Burnette of ASU News…The Morgan Lecture Series of Science will host Dr. Michael Brown, a solar-system astronomer and professor of planetary astronomy from California Institute of Technology (Caltech). He will give a free, public lecture titled “Planet Nine from Outer Space” on Thursday, March 23, at 6:30 p.m., in the Blue Ridge Ballroom of the Plemmons Student Union.
The Morgan Lecture Series in the Sciences was created by an endowment from the G. William Morgan Family. Additional sponsors for this event are the College of Arts and Sciences and the Department of Physics and Astronomy.
“Recent evidence suggests that a massive body is lurking at the outskirts of our solar system, far beyond the orbits of the known giant planets. This object, at a distance approximately 20 times further than Neptune and with a mass approximately 5,000 times larger than Pluto, is the real ninth planet of the solar system,” Brown said.
He will discuss the observation that led to the evidence for Planet Nine and how so massive an object could have been hiding in the outer solar system for so long, as well as the international effort to pinpoint this newest member of our planetary family.
Brown’s memoir, “How I Killed Pluto and Why It Had It Coming,” is on the discovery of Eris and the reclassification of Pluto. It is an award-winning best seller.
Brown will also give a technical talk in the Department of Physics and Astronomy, as well as meet with students, during his visit March 23 from 2 to 3:15 p.m., in Garwood Hall Room 112. His talk will be on “Tales from the Outer Solar System.” He will discuss the discoveries and new views of giant collisions, stellar encounters and planetary rearrangements that are being identified through research and study.
“The past few years have seen an explosion in the discoveries of Pluto and nearby Pluto-sized bodies in the outer solar system, giving rise to a new classification of “dwarf planets,” stated Brown. “Like Pluto, each of these largest dwarf planets has a unique story to tell about the history and evolution of the solar system.”

About the Morgan Science Lecture Series
The Morgan Science Lecture Series was established with a gift from the G. William Morgan Family. Morgan was a 1934 graduate of Appalachian and a health physicist with the U.S. Atomic Energy Commission. The series stimulates scientific understanding and research among the sciences by bringing researchers to campus. Previous speakers include David Suzuki, award-winning geneticist and broadcaster, evolutionary biologist Stephen J. Gould, population ecologist Paul Ehrlich, former U.S. Secretary of Energy Steven Chu and oceanographer and underwater archaeologist Robert Ballard.
