NEXT OCA MEETING
(FREE and open to the public)
Friday May 12th, 2006, 7:30pm
at Chapman University Directions.

Featured Speaker

Ken Croswell

TEN WORLDS: Everything That Orbits the Sun

Ten Worlds

With the discovery of a new world larger than Pluto and three times farther from the Sun, our solar system now has ten known planets. During this talk, astronomer Ken Croswell takes you on an up-to-date tour of them all, showing spectacular color images of the planets and their largest satellites. He focuses on the latest developments beyond Neptune: astronomers have spotted more than a thousand icy objects in the Edgeworth-Kuiper belt, whose largest members are Pluto and the newly discovered tenth planet, 9 billion miles from the Sun. Furthermore, we now know of three moons orbiting Pluto and one moon orbiting the tenth planet. What are these far-off planets and their moons like? What will the newly launched spacecraft to Pluto tell us? And do Pluto and the tenth planet even deserve to be called planets?

Ken Croswell earned his Ph.D. in astronomy from Harvard University and is the author of seven books, including Magnificent Universe and Ten Worlds--the only book with all ten planets. He lives in Berkeley, California.
