Question about Sailor Pluto?
368840
correct me if im wrong, but i thing she already guard the door since before the war between moon and earth, so i think she's much older. it said that after reach age 20 year (i think), they wont get old, look at mamoru and usagi in their future, and look how the earth change alot, so i think setsuna already reach her age limit, and with that look, she cant be still a junior high school like the other.

There is debate over whether Pluto should even be classified as a planet.  It seems out of place with the gas giants of the outer solar system beyond the rock belt.  Also, other similar bodies are being found beyond Pluto that are not being made "planets".  Finally, Pluto has a satellite, or "moon", Charon, which is actually almost as big as Pluto istelf, and orbits very, very close to Pluto.  From Earth, they barely resolve (depending on the quality of the instrument) and appear joined at the hip as it were.  Pluto takes 248 years to orbit the sun.  Since it was discovered in 1930, man has not even observed one of its completed orbits around the sun.  Pluto follows an extremely exaggerated elliptical orbit, which actually crosses paths with the orbit of Neptune.  Thus, sometimes Neptune is the furthest planet from the sun, other times it is Pluto.\n\nUranus rotates about its own axis which is "sideways" (a relative term), at 98 degrees tilt.\n\nNeptune has a Great Dark Spot, which is a storm similar to the Great Red Spot of Jupiter.

read http://en.wikipedia.org/wiki/Pluto\n\npluto is neither a planet nor a comet.\n\npluto does orbit the sun, is ball-shaped, does not have an isolated orbit (a bunch of other similar bodies have similar orbits.), and is not a satellite so it is not a planet.\n\ni have been waiting for this since i was about ten.  i knew that pluto didn't fit the pattern set by the major bodies in the solar system so it was an anomaly.  it just felt "out of place".  now that astronomers have found hundreds of other bodies with similar orbits, classifying "134340 pluto" as a planet is even more irrational.  i feel somewhat satisfied, but i don't know how long this will drag on tho.  this was the right thing to do, believe me.  this does not change anything about pluto or the solar system.  this just corrects the mistake of classifying pluto as a planet initially.\n\nmany astronomers consider pluto and charon to be a binary system, but two small bodies orbit that system.  they are called nix and hydra.\n\nincidentally, "134340 pluto" was never a moon of neptune.  neptune did capture triton. this is why triton has a retrograde orbit.

Nope.  That's my professional (astronomer) opinon.  Here is why:\n\nPluto is a member of a large collection of similar sized objects that orbit the sun in the same region as it.  This is the same situation that Ceres, the largest asteroid is in.  Pluto was simply the first of these icy bodies to be found, we have since found almost 1000 other objects that share orbital space with Pluto.  Many of them are almost the same sice as it, and one (2003 UB313) is in fact larger than Pluto.\n\nNo good defination of planet exists that allows for pluto to be a planet without admitting about 10-100 other objects in as planets as well, unless you simple state that Pluto is a planet in an ad hoc manner.\n\nThe definition that I generally use in my work is that a planet is an object that has cleared it's orbital space of all other small bodies.  All of the main 8 planets satisfy the criteria.  Pluto, 2003 UB313, Ceres and other small bodies do not.

It could happen someday, but it's more likely that Neptune, since it's so much bigger, would just cause Pluto to alter it's path. Gravity bounce, or something like that. Paths can cross without an intersection.

Pluto is the smallest planet, recent reports says that pluto is not further considered as one of the planet cause it is actuallay only 3/4 of the moon...........Pluto has one moon named Charon

Because yesterday evening Mickey Mouse has left Pluto outside of the house door and he has spent the whole night under the open sky. Pluto hadn't either a dog house to keep warm and now is cold because is completely frozen!!!\nIf you mean the other Pluto is very simple;it's cold because it's much too far from the Sun being the farthest away planet of our solar system. Also there is no activity in its inside and that's why ,on the whole, it's extremely cold.

First of all, Charon (Pluto's moon) is not bigger than Pluto.\nPluto has a diameter of about 2274 km and a mass of about 1.27 E22 kg.\nCharon has a diameter of about 1212 and a mass of about 1.90 E21 kg.\n\nBut even if a moon is larger than another celestial body, it should not automatically be bumped up to "planet status".\nAfter all, our moon ("the moon") is larger than pluto, but it is not a planet.

*Pluto: officially the 9th planet in our solar system\n*10th planet: nothing officially has this designation.\n\nIf you are talking about 2003 UB313, then there is a comparison to be made.  They both live in a similar part of the solar system, but it looks like UB313 seems to be a bit redder than Pluto.  Pluto is also known to have a transient atmosphere, not measurements of a potential atmosphere of UB313 have yet been published.

Pluto's atmosphere is super thin and transient, so I would call it's entire atmosphere a "special phenomena."  Pluto more than likely only has an atmosphere when it is at the point of its orbit that is closer to the sun (periheion).  As Pluto continues on its orbit it moves further away, and the flux of light from the sun will more than likely no longer warm the planet woungh for it to maintain the atmosphere.  What little thin atmosphere Pluto has now will freeze to the surface of the planet over next few decades.

The tenth planet is like really great, thanks for asking.  He spins around and around and makes one revolution around the sun about once every several thousand thousand years.  Therefore you might call this tenth planet (he doesn't mind) a chunk of ice, and not really planet-like at all.  But wait, you're saying, Pluto is a chunk of ice and also a planet!  Well, Pluto actually (he's telling me now) doesn't even consider himself a planet, as he's really just a large ice-chunk in the Kuiper Belt.  The tenth planet (we'll call him "Frank", that's what he prefers) is a little peeved that Pluto gets a thousand-brother belt to wear and all he's got is the occasional through-comet.  We can't help you, Frank, I'm sorry.  We're like, a billion miles away.

Let's try to see this from Pluto's point of view.\n\nPluto received news in 1930 that the folks on Earth had proclaimed him as a Planet, putting him in a very exclusive group of Solar System inhabitants.\n\nPluto was very flattered indeed.\n\nPrior to this, he had been minding his own business, hurting nobody, as you rightly pointed out.  Well, almost nobody...  There were those pesky little rocks in the neighborhood that he just had to shoo away, like the little toddlers that sometimes walk right up to you in the mall.  But it wasn't very often, and Pluto was generally very well behaved in his 3:2 resonant orbit with the local neighborhood big guy, Neppy-whats-his-face.\n\nBut hey, if the folks on Earth put Pluto with Neppy, more power to you guys!\n\nBut the truth is, Pluto has been around for a long, long time, quietly doing his rounds.\n\nNow, you Earthlings decide to take away - some say "dethrone" - his title as a Planet.  Oh, the audacity!...\n\nBut in reality, the insult is felt by Pluto's friends on Earth (including yours truly).  Pluto heard about the raucous in August, but you know what?\n\nHe's still doing his rounds in the cold, dark outer reaches of our stellar neighborhood quietly and without complaining.  He's been doing it for many millennia now.  Maybe, when the boredom gets to him - or perhaps when a fit of playfulness seizes him - he may send a icy piece of rock heading our way, but I'm sure he'll aim to miss.\n\nPluto is a nice guy.  He never hurt anyone except those pesky toddler rocks.  I'm sad for him, but he knows he has friends down here.  He and his chums in the Kuiper Belt are probably laughing at Earthlings who can't seem to make up our minds.\n\nI heard Xena was about to call a neighborhood party to celebrate her ascension.  She's pissed.  Maybe she's the one who'll hurl that rock at us...

All of the above are incorrect in terms of the semantics of what "officially" makes a planet a planet. You need to look at the IAU (International Astronomical Union) definition of planet to see why Pluto is now defined as a dwarf planet\n\nFirst, why does Pluto not fit the IAU planet defintion?\n\n(1) A "planet"1 is a celestial body that (a) is in orbit around the Sun, (b) has sufficient mass for its self-gravity to overcome rigid body forces so that it assumes a hydrostatic equilibrium (nearly round) shape, and (c) has cleared the neighbourhood around its orbit.\n\nPluto fails in "c".  Personally, I think "neighborhood" should be definined in terms of an orbital dynamics phase space since it never comes close to Neptune due to the 3:2 resonance  of their  orbits: my opinion and $3.95 will get you decaf latte at Starbucks. (Hmm... Neptune has not cleared Pluto out of ITS orbit either. . . maybe they know about some other icy bodies in Pluto's orbit?)\n\nPluto DOES meet the qualifications  for a dwarf planet.\n(2) A "dwarf planet" is a celestial body that (a) is in orbit around the Sun, (b) has sufficient mass for its self-gravity to overcome rigid body forces so that it assumes a hydrostatic equilibrium (nearly round) shape2, (c) has not cleared the neighbourhood around its orbit, and (d) is not a satellite.
