Does anyone know any interesting facts about Uranus, Neptune and/ Pluto?

The only thing I know and I keep telling all my scientist neighbors is that Pluto probably isn't a planet.

Jupiter has 63 moons, Saturn 56, Uranus 27 and Neptune 13.\n\nSaturn's ring system is best known and the most prominent. Though all four gas giants have rings. Though this is not well known.\n\nI suspect you are working from old information. i.e. out-of-date totals of moons and rings that have since been surpassed by further discoveries. That makes it a bit of detective work as to which planet's historical record you have been reading.\n\nSATURN  \n\nIn 1980 Voyager 1 increased the number of known Saturnian moons from 11 to 19. With Atlas being Saturn XV to be discovered. There appear to be 12 major rings (but many minor ones) and two of those are of recent discovery so perhaps your sources have not caught up with the latest Huygens-Cassini flybys and Hubble telescope surveys,\n\nNEPTUNE\n\nhas five, possibly six other rings and four ring arcs (incomplete rings) within the Adams ring. In order outwards:\n\nGalle \nuncertain    \nLeVerrier \nLassell  \nArago  \nunnamed    \nAdams \n\nArcs in Adams Ring \nFraternité  \nÉgalité  \nLiberté  \nCourage \n\nIn addition to its 13 moons, as of November 2006, there are five known Trojan asteroids of Neptune which have the same orbital period as the planet. They lie in the elongated, curved regions around the L4 and L5 Lagrangian points 60° ahead of and behind Neptune. These are 2001 QR322, 2004 UP10, 2005 TN53, 2005 TO74 and 2006 RJ103. But these are not moons: they rotate with the planet around the Sun.\n\nURANUS\n\nFive large moons (Titania, Oberon, Ariel, Umbriel and Miranda) were known in 1948. The flyby of the Voyager 2 space probe in January 1986 led to the discovery of a further 10 inner moons, bringing the total to 15. But 12 more have emerged since then.\n\nWikipedia lists 13 Uranian rings and NASA lists 10, but both state that two further rings were then found in 2005.\n\nJUPITER\n\nhas too few rings to meet the description provided.\n\nThe main ring is made of dust from the satellites Adrastea and Metis. \n\nInside the main ring is a torus of faint particles known as the halo. The gas torus consists of ions generated by Io's vulcanism that contributes significantly to radiation levels in Jupiter's vicinity.\n\nTwo wide gossamer rings encircle the main ring, originating from Thebe and Amalthea. \n\nFinally, there is a distant and very faint outer ring circling Jupiter backwards—retrograde of its spin. It is not known for sure where the material for this outer ring comes from, but it may be captured interplanetary dust.\n\nCONCLUSON\n\nAs Jupiter has too few rings and Neptune too few moons, you must mean Uranus or Saturn,\n\nI incline towards Uranus as its total of moons stopped at 15, and according to one account its total of rings stopped at 10 for a few years.

http://en.wikipedia.org/wiki/Pluto\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 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

Venus, Uranus and Pluto\n\nI agree with the answer above about Uranus.

in relation to the other planets in our solar system... our moon is bigger than pluto but smaller than the other planets.\n\nin relation to other moons of other planets in our solar system... it is the 5th largest out of all the other planetary satellites.\n\nthe exact figures are at the link below:\n-(this other link might help as well)

Ten. A new planet has been discovered that is approximately the same size as Pluto. It has not yet been formally named. Check http://www.nasa.gov/vision/universe/solarsystem/newplanet-072905-images.html for more info:)

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

UB-313 (also known as "Xena"). This is the only "tenth planet" that has a moon and is larger than Pluto.\n\nThere are several other "planetoids" or "plutinos" including Sedna, Quaoar, Ixion, Varuna, and Orcus.

There are a few things which distinguish the planet from all others, the most obvious is it's blueish appearance.\n\nNeptune is the eighth or, occasionally, the ninth planet from the Sun due to Pluto's eccentric orbit, and the outermost gas giant in our solar system. Although the smallest of the gas giants, Neptune is more massive than Uranus: its stronger gravitational field has compressed it to a higher density. The planet is named after the Roman god of the sea because of its blue methane clouds. Its astronomical symbol is a stylized version of the god's trident (♆).\n\nFaint dark colored rings have been detected around the blue planet, but are much less substantial than those of Saturn. When these rings were discovered, it was thought that they might not be complete, but this was disproved by Voyager 2. Neptune also has 2,500 km/h winds of hydrogen, helium, and methane that gives the planet its blue appearance.[citation needed] At the time of the 1989 Voyager 2 flyby, it had in its southern hemisphere a Great Dark Spot comparable to the Great Red Spot on Jupiter. Neptune possesses nine confirmed moons and four awaiting confirmation. Neptune's largest moon, Triton, is notable for its retrograde orbit, extreme cold (38K), and extremely tenuous (14 microbar) nitrogen/methane atmosphere.\n\nDiscovered on September 23, 1846, Neptune has been visited by only one spacecraft, Voyager 2, which flew by the planet on August 25, 1989. In 2003, there was a proposal to NASA's "Vision Missions Studies" to implement a "Neptune Orbiter with Probes" mission that does Cassini-level science without fission-based electric power or propulsion. The work is being done in conjunction with JPL and the California Institute of Technology.[1]

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.

many favor the reclassification of the bodies in the solar system into three groups, the rocky terrestrials, the gas giants, and the ice dwarfs.  there are hundreds of bodies that orbit the sun farther than neptune known.  these include bodies like pluto, quaoar, sedna, and 2003 UB313.  this is also called the kuiper belt.  pluto was the first kuiper belt object discovered.
