I think the discovery of Eris was a major deciding factor in the decision to define "dwarf planets." Eris is estimated 27% more massive than Pluto, so if Pluto was a planet Eris would have to be one too...

hmmm...

so A-E-I-O-U and sometimes Y (and W?)

and M-V-E-M-J-S-U-N and sometimes Pluto (and Eris?)

Wouldn't it make more sense for the whole phrase "dwarf planet" to be a noun in its own right, as is suggested by the Oxford Dictionary of English? Perhaps this would clearer if it was hyphenated.
You're probably right about that. But really, I rest my case. It's not incorrect, I think, just confusing to the general public. I don't like having to explain to people why a dwarf planet is not, in fact, a planet even though the word is right in there. It should be totally unnecessary.

That said, I'm not really losing sleep over it.

Yeah, but now I am! There's a grammatical nightmare afoot.

It's a red herring. Neither red, nor herring.

Sedna? Haumea?

Quaoar!

How can you deny a dwarfie named Quaoar?!

True...but Quaoar only has a cool name, Sedna has a pretty orbit and Haumea is beautifully oval:biggrin:

I hadn't realized until now that the Earth is trans-Neptunian.

I think I am too old. It doesn't look sexy to me.

You're not too old, you're just spoiled by Marzena.
 
Borek said:
This is ridiculous. How can a dog be a planet.

Well, if you feed it enough...

Perhaps you're more of a spherical guy?

What's next: you going to tell me that Cruithne is no longer our moon?

NO WAY! I never knew about this! Thanks Gokul, this completely blew my mind tonight.
