Yes, the general consensus appears to be that another planet has been found, which is currently designated 2003 UB313, it is about 2,800km across - a world of rock and ice and somewhat larger than Pluto. Scientists say it is three times as far away as Pluto, in an orbit at an angle to the orbits of the main planets. \n\nThough it should also be understood that the scientific community are also considering a redefinition of planet, which might reclassify not only this new 10th planet and Pluto has not being planets.

by the name pluto and uranus\n\nummmm emailance i really don't think ur gonna get a story at the end

Heck no.  We are going to the moon that year.  Pluto is a long way away.  If your thinking about thye robotic "new horizons" program, that will land on pluto in July, 2015.  Thats 5 years later.  I apolligize, but no.\n\nThe key is timing.  Only once every several hundred years can the planets align for a rocket to be sent to pluto.  It will last a while, but after that, your waiting for a long time.  I estimate we will return there in...say...2567 or something around that.  If we ever go to there...\n\nUnless I hibernate in my studies and become a god of wisdom and knowledge so i can path a path of good and truth to walk/teleport faster than anyone to get there.

The first spacecraft to visit the planet Pluto lifted off from Earth in January of 2006 and is expected to reach Pluto on July 14, 2015.  Pluto is so far from Earth that not even the Hubble Space telescope is able to take clear pictures of it.  Pluto's distance from the sun varies between 30 AU and 49 AU.  One AU is the distance between the Earth and the sun.  Pluto is so distant that man will very likely not visit for many 100's of years yet to come as we do not possess the technology to make the voyage to Pluto within an acceptable period of time.  Compare this to the distance between Earth and Mars which is only 0.37 AU (35 million miles).

I have been doing a presentation on Pluto is not a planet.\n\nI put up a bulletin board with the pictures of the planets with special pages showing Ceres, Pluto, and Eris.

NO, WHEN PLUTO WAS FORMED IT WAS STRAIGH AWAY GIVEN NAME PLUTO WAS DISCOVERED BY  Clyde W. Tombaugh \nDiscovered on February 18, 1930 \nABT THE MISTRY OF PLANET-X THEN ITS THE PLANET SOMEWHERE FAR FROM PLUTO.

*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.

Nice links. I would think that Pluto is still a planet. Its mean radius relative to earth's radius is approximately 0.46. So the diameter at equator might be some 3600 miles. By comparison, a satellite like Nereid, which orbits the planet Neptune, is no more than 200 miles in diameter. At its size Pluto must be a planet.\nI am not sure about Sedna. If we think about the 10-th planet, or the "X" planet, it was thought to be three times as massive as Saturn, and nearly six billion miles from the earth. It looks to me that Sedna might not be our 10-th planet. But then again, perhaps we just have to wait and see.

http://en.wikipedia.org/wiki/Pluto\nhttp://www.iau.org/fileadmin/content/pdfs/Resolution_GA26-5-6.pdf\n\non 24 august 2006, the international astronomical union reclassified pluto.\n\npluto does orbit the sun, is ball-shaped and is not a satellite, but it does not have an isolated orbit (a bunch of other similar bodies have similar orbits.) so it is not a planet.\n\ni have been waiting for this since i was about ten when i learned 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. many planetary astronomers are satisfied that the definition is rigorous enuf. i can accept that the definition is flawed, but i can not accept that "134340 pluto" is a planet.\n\nthis 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\nthis same thing happened has happened before.  in 1800, an astronomer found a body orbiting the sun between the orbits of mars and jupiter and thought it was a planet.  astronomers finally stopped classifying them as planets after they found several other bodies with similar orbits, and no one thinks ceres, pallas, juno, and vesta are planets today.\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

Depends on how long ago you were in school -- Pluto is so far away that for many years we thought it was larger than it has turned out to, in fact, be.\n\nThe most recent value I have for the diameter of the two planets is:\nMercury = 4879.4 km\nPluto = 2302 km\n\nThen, of course, there's the debate about whether or not Pluto is even truly a planet . . .

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.

To answer your second question first (I'm just an ornery cuss), Pluto is still a member of the Solar System. It's no longer considered a planet, though. It is now called a dwarf planet because of its size and extremely anomalous orbit (so look it up already).Just like the moon. asteroids, etc. it is still part of the Solar System.\n\nAs to the 1st part of your question-------Usually, as long as Mickey gives him table scraps instead of that crap from the can.Woof!Woof!

Pluto (planet), ninth planet from the Sun and outermost known member of the solar system. Pluto was discovered as the result of a telescopic search inaugurated in 1905 by the American astronomer Percival Lowell, who conjectured the existence of a distant planet beyond Neptune as the cause of slight perturbations (see Orbit) in the motions of Uranus. Continued by members of the Lowell Observatory staff, the search ended successfully in 1930, when the American astronomer Clyde William Tombaugh found Pluto near the position Lowell had predicted. The new planet’s mass, however, seemed insufficient to account for the perturbations of Neptune, and the search for a possible tenth planet continues.\n\nPluto revolves about the Sun once in 247.7 years at an average distance of 5.9 billion km (3.67 billion mi). The orbit is so eccentric that at certain points along its path Pluto is closer to the Sun than is Neptune. No possibility of collision exists, however, because Pluto’s orbit is inclined by more than 17.2° to the plane of the ecliptic and never actually crosses Neptune’s path.\n\nVisible only through large telescopes, Pluto is seen to have a yellowish colour. For many years very little was known about the planet, but in 1978 astronomers discovered a relatively large moon orbiting Pluto at a distance of only about 19,000 km (12,000 mi) and named it Charon. The orbits of Pluto and Charon caused them to pass repeatedly in front of one another from 1985 to 1990, enabling astronomers to determine their sizes fairly accurately. Pluto is 2,284 km (1,420 mi) in diameter, and Charon is 1,192 km (740 mi) in diameter, making them even more like a double-planet system than are the Earth and its moon. Pluto was also found to have a thin atmosphere, probably of methane, exerting a pressure on the planet’s surface that is about 100,000 times weaker than the Earth’s atmospheric pressure at sea level. The atmosphere appears to condense and form polar caps during Pluto’s long winter. The first map of Pluto’s surface was made by the Hubble Space Telescope. It shows vague light and dark regions of unknown origin.\n\nWith a density about twice that of water, Pluto is apparently made of much rockier material than are the other planets of the outer solar system. This may be the result of the kind of cold-temperature/low-pressure chemical combinations that took place during the formation of the planet. Some astronomers have suggested that Pluto may be a former satellite of Neptune, knocked into a separate orbit during the early days of the solar system. Charon would then be an accumulation of the lighter materials resulting from the collision.

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...

July 29, 2005: "It's definitely bigger than Pluto." So says Dr. Mike Brown of the California Institute of Technology who announced today the discovery of a new planet in the outer solar system.\n\nThe planet, which hasn't been officially named yet, was found by Brown and colleagues using the Samuel Oschin Telescope at Palomar Observatory near San Diego. It is currently about 97 times farther from the sun than Earth, or 97 Astronomical Units (AU). For comparison, Pluto is 40 AU from the sun\nThe planet's temporary name is 2003 UB313. A permanent name has been proposed by the discoverers to the International Astronomical Union, and they are awaiting the decision of this body before announcing the name. \nAm I right U_EVERYONE_K

Yes. Pluto has an eliptic orbit (not perfectly circular) which means that sometimes it will be closer to the sun than Uranus and therefore the 8th.
