That deff is quite unclear, How do we know a comet from a planet? size? well we have found Kuiper belt objects (Astroids beound pluto) 2/3s of pluto's size, which leaves room for bigger ones. What about shape, size and orbit in one? If it is spherical (or close to that), large enough to have a gravitational pull that keeps a (somewhat) steady atmosphere and makes an orbit that could be described as circular, is it not exactly what we're looking for?

not all planets have a steady atmespere, Plutos freezes solid each of its winter then thaws again later. other planets also have thin atmespheres like mercury and mars. Also some comets and astroids have thin atmespheres.
As for orbit the only planet that orbits diffrent then the others is pluto so far. No planets orbit is a trule curcle, closer to an oval and plutos is the most oval like of them all so far.
Also so many things make orbit this isent much of a way to tell.
So all areas are in conflict, if we go to the minamum size a mass needs to be shaped sphereicly and have some gravatation it would raise the planet count to about 16

If they don't even have the definition for 'planet' yet?

becides Naoko said the series was done anyway, and since SM anime was based on the Manga mainly this makes it a bit hard to continue if the mnaga will not. That would be cool if she changed her mind ;D But don't expect for that to happen

Then how in the world can scientists define 9 planets in the solar system? Just continuing from what you said, being an advanced science and astronomy student, there have been a couple of rumours a few years ago suggesting that Pluto is not a planet. Pluto is small for a planet, but most people are used to reffering to Pluto as a planet, not a space rock or a moon of Neptune.

Well, it's definately not a moon of Neptune, because it doesn't orbit Neptune.

that's true, but people still aren't sure whether Pluto is actually a planet or a space rock.

It more than likely not going to happen that we shall have another Sailor Moon Season coming along in the future. It would be nice though..
And as far as Sedna, it was not confirmed as of yet... and also, Sedna would be a cool name for a Sailor Senshi too!
Maybe if we ever had another series of BSSM... the newly found planets should make another catagory of senshi. So then there will be the Inners, Outers, and maybe Super Outers! Lol!

Yeah pluto is a tough planet....wait let me restart.
Yeah pluto is a tough object floating in the sky. It orbits the sun so it would have to be part of the Solar System! right?

Well...a lot of things orbit the sun. Humans "orbit" the sun. Are we planets? For a closer (less chessier) example, comets orbit the sun too. That's why the come around every 100 (or so) years because of their orbits (they have hugeee orbits but still, its an orbit).
That would be so sad if Pluto was not a planet. It would like totally break the Sailor Moon story XD.
I wouldn't want a new planet anyway. Besides, there is a limitation (not defined tho) of..."a planet" in a solar system. There are like thosands of particles and just crap orbiting our Sun. But its nice to think we only have 9 planets (because of Sailor Moon). I think scientists are just stretching it a bit to call Sedna a planet. (I'm sure its a "planetoid" tho)
Anybody notice something is just "bubbling" with this Sailor Moon thing? Sailor Moon ended, (count em) 8 years ago. Why is Japan suddenly doing a live action series? Why is the Sailor Moon site...being...all updated XD? Why is there a new kind of Sailor Moon art (Takeuchi is using CG now in her art). It just seems like there's a Sailor Moon revival.
I also believe Sailor Moon was the best selling series for Nakayoshi...maybe because Nakayoshi is losing money they want to bring back Sailor Moon to get more profit? Then it could be very likely Sailor Moon to have some new continuation.

I wouldn't want a new planet anyway. Well, a new planet would have to sides, a good and a bad. The good side *for me* would be that I love anything new and exciting, and for me, if any of you read earlier, I'm a science and atsronomy student, I love finding out about new planets, and a new planet would be awesome to create a new character for. The bad side would be that there'd be more information to remember (like for tests and things) and it would also wreck the balance of the planets.

90377 Sedna is classified as a planetoid, meaning planet-like, is an old synonym of asteroid.
Prior to the 1990s only nine planets were known (all of them in our own solar system); as of the 3rd of November 2004, 133 are known, with all of the new discoveries being extrasolar planets, sometimes known as "exoplanets"
Sedna is a 1180–2360 km (730-1470 miles) diameter object. The diameter is still uncertain but believed to be between 1/2 and 3/4 of Pluto's. Several news sources have already reported Sedna as the tenth planet. But that is not generally accepted by astronomers. Another possible planet is Orcus, an object with an orbit and mass similar to Pluto's. Other candidates include Quaoar and Varuna.
