This is a wise decision.
Pluto was always a nutty anomaly, with its orbit, and later its asymmetric appearance.
It always seemed more like an asteroid.
Personally I would consider an object with an atmosphere that orbits the sun a planet. Moons would still be moons because they orbit planets.
Absolutely, this was the most reasonable decision. I was disheartened a couple of weeks ago when they were going to say there were 12 planets, including Pluto, and the Plutons, yadda, yadda. This definition makes the most sense.
Also, under this new system of categorization, a "dwarf planet" isn't considered a planet at all. It's bizarre. Only a very small fraction of the world's astronomers voted at all. Hopefully, this awful decision will be overturned soon and we can get something like terrestrial, gas giants, and plutons/dwarf planets, ALL of which should be considered planets. Thank God an intelligent astronomer is leading the charge to overturn this farce.
