Sorry, Pluto: You’re really not a planet

What does this article tell us about the roles of definitions and language in the natural sciences?

“What finally led the International Astronomical Union to reconsider Pluto’s status was Brown’s discovery of another Kuiper belt object, Eris, that was actually a bit more massive than Pluto. Aware that this would probably just be the first of many, the IAU voted to approve a new definition that would eliminate all of these objects from the list of planets — rather than continue to add more and more planets in future years.”

  1. As it turned out, Pluto is far more interesting than scientists had hoped for; and with the added “controversy?” What better way to exact a little retribution for astronomers daring to venture into his underworld realm?
