Unfortunately, despite a huge pile of mathematics, and a seeming score with Pluto, it turns out that case was actually spurious, Pluto is not sufficiently massive to have been noodled to exist via the maths. The Lowell Observatory had announced several possible locations for a ninth planet, so their assertions in regard to Pluto are somewhat diluted as a result, and then when the mass was determined, the Lowell Observatory predictions were all nulled out.
A really 'large' planet out there, and not in the plane of the ecliptic, is seemingly ruled out via dynamical effects not seen on the known planets, btw.
As for this 10 earth masser, Idunno. This prediction actually, to me, gets more plausible the further out it might be.
The problem I see is:
1. It is hard to imagine a planet that massive forming that far out, given the spareness of the available material even during formative years of the solar system.
2. If it formed close in and was somehow thrown to such an extended orbit through gravitational interaction with other planets, it's perihelion should still be somewhere close to where it's original orbit was. It's not clear to me what could have pumped its perihelion so far out from where it was formed.

Yeah, as far as I'm concerned Pluto should get planet status back, if only for reasons of tradition.
Then all the plutoids similar in size to Pluto should also get planet status. Definition should have real meaning besides nostalgia.

That's true; but I specifically stipluated reasons of tradition, rather than strict scientific accuracy. Basically the same sort of reason that The Plough is recognised as an entity in its own right, despite its more accurate status as an asterism of Ursa Major.
At the age of five, Skagra decided emphatically that God did not exist. This revelation tends to make most people in the universe who have it react in one of two ways - with relief or with despair. Only Skagra responded to it by thinking, 'Wait a second. That means there's a situation vacant.'

Which is better:
To die with ignorance, or to live with intelligence?
Truth doesn't accommodate to personal opinions.
The choice is yours.

That's a name, not a classification. A name can contain any degree of tradition desired. A classification should be useful first.
If any plutoids similar in size to Pluto qualifies as a planet, it reduces the usefulness of the planet classification, since Pluto is really a very minor body and probably quite average for a plutoids and there could well be hundred or even thousands plutoids not far smaller than Pluto.

And the term "atom" should be reserved for a truly indivisible object, because philosophical tradition!

No, silly.
The nemesis of Popeye!
Oh fuck, that's Bluto! I always wondered why I never saw Bluto woof and lick his own testicles while spinning on his axis and having his own Zodiac called "Nemesis of Spinachman".
What I just said makes perfect sense okay?

The IANA cares more about rational classifications than tradition - and I'm pretty sure they don't recognize The Plough / Big Dipper at all. AFAIK, they don't name asterisms.
