Congratulations...you won. I don't know exactly "what" you think you have won...anyway...

If you really want to be involved in a "scientific victory", then you can start by answering the NUMEROUS questions asked of you in other threads. After all, now that you have "won" your victory, you should have plenty of spare time to devote to those questions.

Please don't be silly...there are no "scientific proofs" involved here...

Just a group of astronomers who felt it necessary to re-define the "labels" used when describing the objects in our solar system...

They are LABELS...that's all...

If I choose to call all the objects that orbit the Sun Spleegals, then my usage of that descriptive word is no better/no worse than any other "label"...

What we call something does not change what that something is...

The problem was that Pluto was always a weird one. Astronomers were uncomfortable and looked askance at it, with its diminuitive size and strange orbit. It just didn't fit in. It had to go.

That's not totally correct. There is the 28 February 2001 position statement on the definition of a planet from the IAU Working Group on Extrasolar Planets (link):

"1) Objects with true masses below the limiting mass for thermonuclear fusion of deuterium (currently calculated to be 13 Jupiter masses for objects of solar metallicity) that orbit stars or stellar remnants are "planets" (no matter how they formed). The minimum mass/size required for an extrasolar object to be considered a planet should be the same as that used in our Solar System.

2) Substellar objects with true masses above the limiting mass for thermonuclear fusion of deuterium are "brown dwarfs", no matter how they formed nor where they are located.

3) Free-floating objects in young star clusters with masses below the limiting mass for thermonuclear fusion of deuterium are not "planets", but are "sub-brown dwarfs" (or whatever name is most appropriate)."

This is consistent with the IAU definition for Solar System planets, which I anticipate will be used for extra-solar planets by analogy.

Who came up with the term 'dwarf planet'? Whatever happened to the much more elegant sounding 'planetoid?'
As they discover more I'm sure the usual joke names will be proposed. Sneezey, Dopey, Bashful....Gimli.

The irony of H_C claiming victory due to logic and clear thinking is simply astonishing.

That occured to me too. I liked the term Plutino!

H_C, youir claim of logic is so misplaced. If you honestly think that the New Horizons mission shouldn't be going to Pluto, then your own horizons are very narrow indeed. If you knew anything at all about science or astronomy, then you'd understand that the quest to explore is an integral part of it.

We know very little about Pluto and far less about the other Kuiper Belt objects. This is a massive area to explore and the secrets to our own Solar System formation may lie therein.

What is abundantly clear is that you have no desire to explore. You see this as being some competition and know very VERY little about any of the science involved with the exploration of the Kuiper Belt. Many people on this thread and others are waiting for some answers, rather than your pointless trumpet blowing at a decision which has very little impact on science.

Whatever Pluto is called (I think 'Dwarf Planet' means that the word 'Planet' is still in there, so where exactly is your 'victory' for logic?) it has nothing to do with what Pluto looks like, how it behaves or its what its surface temperature is etc. I for one can't wait to see its surface. Try and get involved in the science or go somewhere else with your boasts.

I'm sure this is going to be a stupid question, but is the barycentre of the earth luna system inside or outside the earth?

clop

inside

There are no stupid questions, only stupid answers!

But FYI, it's inside the earth.

Yes, the term "dwarf planet" is misleading. I would have liked if they had selected the venerable "planetoid" instead.

I think it was a bone tossed to the "Pluto is a planet" crowd. The important thing is not the nomenclature, but the classification scheme. Pluto is now classified with other trans-Neptunian objects which is has a lot more commonalities with. It doesn't matter to me if they are called KBOs, TNOs, Plutonians, Plutinos, or dwarf planets. They are rightfully classifying them as a class of objects different from the 8 "classical" planets. In addition, there is a lot of empirical data to support the notion of "clearing the orbital neighborhood", so I think this scheme is standing on solid, scientific legs.

It is also classified with one, and possibly more, non-trans-Neptunian objects, which it doesn't have a lot of commonalities with - namely, Ceres and possibly some of the other largest asteroids.

Also, is Pluto still a Trans-Neptunian object when it is inside the orbit of Neptune?

["dwarf planets"]
I basically subscribe to David Jewitt's comments on the resolution. His comment on 5A(2) hits the nail quite well, I think.

After resultion 6B failing 6A remains as a funny accident. Pluto is the prototype of KBOs and the prototype of plutinos. Well, I didn't need an IAU resolution to know this.

As the taxonomical brawl unfolded I found all of David's view on the several proposals quite entertaining.

That is true. I think that Ceres is physically very similar to Pluto, but orbitally it is completely different.

Before, Pluto was the "oddball" planet. Now, Ceres will be the oddball dwarf planet! LOL

If there is empiricism behind the idea of clearing the neighborhood then they have failed to present it. That seems to be the reason for giving special exemption to the classical planets... because they don't fit their own criteria.

Wasn't the Gingerich committee an attempt at this? They screwed up completely and will remain in my memory as those who, after two years of preparation, were unable two write down four bloody paragraphs in a remotely coherent fashion. But at least they had their proposal stuffed with a lot of meaningless gibberish.

And then we are presented this gem of irony:
Now, that's bold! While his critique is certainly not too far off the mark he and his group did as bad themselves. There are seven people who should refrain from talking about appropriate language for a while.

Other than the term "pluton" I think the first definition was the best. It was based on inherent properties --what an object is. THe one that god passed is based on sytemic properties, or how an object relates to other objects --where an object is.

And then they leave us without a definition of the criteria they want to use. How is "cleared the neighborhood" more scientific when they have not defined it empirically? Now, some people are trying to argue that "clear" means "dominant" or resonant. They still have not defined the range... so they would limit the range to .1AU for one object and 10s of AUs for other objects.

The first definition was confusing because it was new. If they had dropped the idea of "pluton" and listed subclasses then it would have been much better. Despite working with experts from other fields, they didn't present it well.
