i feel somewhat vindicated. i have known since i was about twelve that pluto does not have the physical and orbital characteristics that fit the pattern set by the major bodies in the solar system. later, after the discovery of hundreds of similar bodies with similar orbits, i knew this was inevitable.
the international astronomical union defined three terms "planet", "dwarf planet", and "small solar system body". this does not change anything about the solar system or pluto. it just corrects the mistake of classifying pluto as a planet initially.
because pluto orbits the sun, is round, orbits the sun with a bunch of other similar bodies with similar orbits, and is not a satellite it is a dwarf planet.
(1) A planet is a celestial body that (a) is in orbit around the Sun, (b) has sufficient mass for its self-gravity to overcome rigid body forces so that it assumes a hydrostatic equilibrium (nearly round) shape, and (c) has cleared the neighborhood around its orbit.
(2) A dwarf planet is a celestial body that (a) is in orbit around the Sun, (b) has sufficient mass for its self-gravity to overcome rigid body forces so that it assumes a hydrostatic equilibrium (nearly round) shape, (c) has not cleared the neighborhood around its orbit, and (d) is not a satellite.
(3) All other objects orbiting the Sun shall be referred to collectively as "Small Solar System Bodies".

Poor Pluto. First a stupid dog. Now a Dwarf planet.

happy as Larry. Pluto has joined its rightful family, like a kid who had been kidnapped being returned to his rightful family.
It is great news.
Please stop all this silly nostalgia - most of the people complaining have never given Pluto a thought from one year to the next.
And these people who say "what gives them the right?" What an idiotic thing to say. All kinds of re-classifications go on in science all the time, as new knowledge comes to light.
I ask, how come people who know next to nothing about the planets or astronomy in general, can complain. It is really idiotic.

yeah of course its been our planet for 76 years, ever sinc eits discovery in 1930.
However despite my love for Pluto, i really think that it was a mistake to even include it in the first place.
What i hope for right now is that Pluto will still be respected and remembered even after it leaves the Planet Club.
GoodBye Pluto!

No. Why would anyone have an emotional attachment to a planet anyway?
It does kinda suck now though, because I'll be thinking there are still 9 planets for a while now, and I'll sound stupid when I say 9 instead of 8.

Not sad at all. Pluto is still Pluto. A rose by any other name is still a rose. Pluto is still out there. Not something to get your knickers in a twist about.

No one asked PLUTO? ......I think they should have asked first before giving him the boot.....really PLUTO has always been around and why spoil our enjoyment of having this little planet in our solar system...PLUTO didn't do anything to hurt anybody....bring PLUTO back !!!......no matter what they say...I'll always think of PLUTO as being a REAL 100% PLANET....

Nope. It was the right decision, otherwise we'd be stuck with an ever-growing list of new planets - way too messy!

Yes. The definition they came out with earlier was better.

Pluto doesn't care so why should I?
