The Sun's 10th planet...?

[Sage]

Sedna could be the tenth.

"While NASA remains intentionally vague, promising only a news conference Monday, The Australian has the details. The new planet, dubbed Sedna after the Inuit goddess of the sea, is 3 billion km further from the sun than Pluto, and is slightly smaller at 2000km in diameter. This discovery has apparently reignited the debate as to how big a solar object must be in order to qualify as a 'planet', but it is significant nonetheless."

 

[Darin]

Pluto is not classified as a "planet" anymore.

 

[Famine]

Pluto IS classified as a planet, due to the fact it has a moon - Charon - orbiting it. Charon is the largest moon in terms of moon-to-planet size ratio, and is one of the larger moons in the Solar system - certainly waaaay bigger than Mars's jokes "Phobos" and "Deimos".

Some Kuiper Belt objects also have smaller moons orbiting them, which is nice and weird.

No its not. I read it in my sceince book. From what I read, they said Pluto is not classified as a planet due to the entire planet is ice. But it does have gravity, but still its entirly ICE.

That's the dumbest reasoning ever, Darin.

Famine is right.

I thought we already had 11 planets. I know there have been bodies beyond Pluto that some have classified at planets.

 

[The359]

Pluto is indeed a planet as of right now, at least officially. It has a moon and it is bigger then anything else we've found out there. The closest things out there are "planetoids". Planet-like but closer to asteroid sized.

I'd say that if we don't accept Sedna as a planet, then we might as well not include Pluto. They sound so similar that it'd be dumb just to accept one of them.

It would be nice if you would shut the hell up...

 

[Event]

who cares, it's not like we'll ever visit the planet...

Klostrophobic isn't exactly known for sugar-coating anything, you know.

On topic, Sedna sounds awfully small to be considered a planet, I'll leave the scientists to draw their conclusions anyway.
And just because Phobos and Deimos and all disfigured and look like something the cat coughed up, they're still not good enough reasons to mock them, Famine.

Yea, I know that. We all know he sucks. But im not going any further than that.

 

[Famine]

I'll mock them all I like. Just as I shall mock Uranus for not only having the silliest name, but for also being the only planet crappy enough to not have moons named after gods... Uranus's moons are all named after Shakespearean characters - how lame is that?

Very lame. Are they cool names like Othello, Rosencrantz and Guildenstern or lame names like Hamlet, Juliet and Horatio? I know I could probably research this information, but I'd rather ask you.

Rosencrantz and Guildenstern are dead.

 

[Famine]

I count:

Ophelia
Desdemona
Stephano
Juliet
Titania
Bianca
Cordelia
Rosalind
Belinda
Cressida
Portia
Puck (really)
Umbriel
Miranda
Ariel
Oberon
Sycorax
Caliban
Setebos
Stephano
Prospero

Then I run out of patience...

 

[daan]

You missed 1986U10

Must be from that well known Shakesperean play, 1986U10 and Puck

 

[Famine]

Imagine the astronauts of the future:

"We're orbiting Rosalind, at an altitude of approximately 120 miles"

"Orbiter to Puck Station"

"Errr, Juliet, we have a problem"

 

[daan]

And then they'll be attempting re-entry to Uranus.

(Sorry. Couldn't resist.)

ANYway....

Pluto is a planet officially. Your science book is written by an idiot.

didnt they think that there was a planet after pluteo like "Planet X" is it the same one they are talking about?

"Is there another planet lurking beyond Pluto, the planet farthest from the sun?

Some scientists think so.

According to space researcher Dr. John Matese, there may be a large and mysterious object circling the sun about TK light-years beyond Pluto. And it could be about three times the size of Jupiter, the biggest planet in the solar system!

The clues? Matese noticed iceberg-like lumps of rock known as comets

orbiting past Pluto that were moving in an unusual direction. If a comet passes by

a large object, the object’s gravity can tug the comet out of orbit. Dr. Matese thinks a large, undiscovered planet may be the cause of the comets’ bumpy ride.

No one knows for sure if a tenth planet really exists, but stay tuned for future reports on the mysterious Planet X."

ummmmmmmmmmmm...............i dont think so...

 

[Famine]

Pluto seemed to be exerting a bigger gravitational force than it ought to, so they came up with another planet, called "Planet X". That planet is Pluto's moon, Charon.

In fact, Pluto and Charon are often referred to as a "double planet", since Charon is so similar in size.

 

[Shadow]

but in that looney toons episode they mention pluto, its moon, and "PLANET X"

but thanks for clearing that up anyways

 

[Sleek Stratos]

I'd stand up and debate against you Famine, but I have far more important arguments to lose at. I jest, I jest.

Frankly, I had no idea Uranus had moons. It's bad enough it looks like it's tipped over.

 

[Jpec07]

I heard something in the news about a 10th planet a couple years ago. Unless this is a new one, then we have 11 (although the one I heard about was said to be more of an asteroid than a planet; mainly because of its size and supposed chemical makeup). Personally, I don't think that we have a shot at reaching planets beyond Jupiter before my life is up (and Jupiter's pushing it), so I don't really care about the planets beyond the nine I was taught in elementary school...

Until I saw this thread, I never knew Pluto had a moon.

now that made me laugh out loud in class! thanks!

some boffins were discussing this on the news....the scientific world is split as to whether they believe that pluto is a planet or not....officially it IS a planet, youre right but not all scientists agree....some believe its just a large lump of rock and ice...where as planets this far from the sun are just big lumps of rock and ice...see the difference?

 

[halfracedrift]

What's "TK" light-years?

And.. I have one question.. Coments like Halley's comet only come by Earth every 76 years or so. Why? (not so long.. why does it come back!) Does the sun extend it's gravitational pull beyond Pluto, to a point where it can slow down a coment and pull it backwards? If it is, then we really can't deny the POSSIBILITY of another planet, or even two existing..
