Pluto, Eris, and the Dwarf Planets of the Outer Solar System
Exploring Space Lecture webcast live on Tuesday, March 20, 2007
Speaker Mike Brown
Mike Brown is Professor of Astronomy at Caltech and the discoverer, along with colleagues, of Eris (formerly known as 2003 UB313), Sedna, Quaoar, and other TNOs (Trans-Neptunian Objects). We now have the capability of detecting Kuiper Belt Objects, at least the larger ones, directly, using Earth-based telescopes. Speaker Brown and colleagues have discovered several of them, including Sedna, Quaoar, and Eris. Pluto has lots of company! But are these really "planets," or was Pluto merely the first discovery of an entirely new class of objects? In 2006, the International Astronomical Union, the gatekeepers of astronomical nomenclature, re-defined the term "planet" to reflect our much-increased knowledge about our Solar System and, in the process, Pluto lost its planetary status. Its not a matter of discrimination; our knowledge growth merely exceeded the limitations of existing terminology.
