What Makes a Planet?


Subject:
Astronomy , Planets

Description:
Brief introduction for the layperson about the definition of what is a planet and about the 2006 controversy about whether Pluto is a planet. This site notes "there are many things that make Pluto quite different from the [other eight] planets," so that it is "very hard to classify Pluto with the rest of the major planets." From a professor in the Department of Astronomy at Cornell University.
