SUMMARY
Leading astronomers officially reclassified Pluto as a non-planet during the 26th General Assembly of the International Astronomical Union (IAU) in Prague, reducing the number of recognized planets in the solar system from nine to eight. The new definition states that a planet must clear its orbital neighborhood, a criterion Pluto does not meet due to its location in the Kuiper Belt. This decision has sparked debate regarding its implications for education, astrology, and future astronomical classifications. The classification of celestial bodies, including Pluto and Ceres, reflects their physical history and evolutionary context.

Are we being just a bit geocentric about the Solar System?

Such bad puns can't be ignored.

"Plutoed" chosen 2006 word of the year

"Plutoed" was chosen 2006 Word of the Year by the American Dialect Society at its annual meeting on Friday.
To "pluto" is "to demote or devalue someone or something" much like what happened to the former planet last year when the General Assembly of the International Astronomical Union decided Pluto didn't meet its definition of a planet.

That has such a nice ring to it, it really adds to the list of possible phrases:
"This is the hardest thing a manager has to do..."
"We've decided to use you as our on-call busboy." (How my first ever real job ended).
"You remember what happened to Pluto? When you think about it, that wasn't so bad, and now that you mention it..."

So I guess that probe flying in space somewhere showing 9 planets is obsolete...
