The question is does this object consitute a planent ? Depending on your point of veiw, what di you think consitutes a planet, as opposed to an asteriod, comet, or piece of debris

isn't a planet, by definition, anything orbiting a star? cause aren't some of juipters moons bigger than pluto? so size doesn't matter...

Yes. Kuiper Belt objects do orbit the sun, all of them no mattter what the size, about every 11, 000 years. So do asteriods between Mars and Jupiter.

So size and orbiting them sun do not solely define a planet. Maybe the combination ??? I do not know.

Maybe it's something to do with how elliptic the orbit is...

I have a question about this: wasn't the tenth planet discovered a while back and named 'Charon' after the ferryman on the Styx river?

What does the new name mean - I don't recognise it from mythology...

Charon is Pluto's moon.

(i think do not quote me on that)

isn't there also a so-called "planet X", which distorts pluto's orbit? something about pluto's orbit being all weird so there's gotta be another planets gavity working on it or something like that?...*isn't too sure*

seems a bit odd though, having an Inuit deity out there with all those Roman ones. Is it because it's so cold, being so far from the sun?

I just saw an ABC news report saying that is was the 'most distant' object ever found in our solar system.

It's because the new "planet" consists largely out of ice.

yes Genius, pluto's orbit is being altered by the so called Planet X. They think it might be a dead star.

My Very Educated Mother Just Showed Us Nine Planets, Suckah'!

Edit! genius

I've also heard this planet X theory... I heard just what you did, something is pulling and no one knows what. I can't find anything on line about it... I didn't look.

Yeah, it's what you do with your planet that counts 😉

The 'new' planet is actually called 'Sedna'. It is the Inuit Goddess of the Sea. That would explain why they didn't choose the Roman/Greek name, it's already taken. 😀 See also: [url]http://www.inuitgallery.com/sedna.shtml[/url]

Counting the planets...

Around 1800, Hegel published a metaphysical proof that there are exactly 7 planets in our solar system, just weeks before Gauss predicted the orbit of the minor planet Ceres, which was later confirmed by observation.

Cosmic ph*ckup or the dialectic at work 😉?
