What is the newest planet discovered,in placed of pluto?
820302
Given that pluto has been demoted from the premier league of solar bodies, and no-one else has been promoted to replace it, the most recent planet discovered in our solar system is Neptune on September 23, 1846.\n\nHowever, planets have been discovered orbiting distant stars, 28 have been discovered in 2006, according to the list on the second website below. But these don't have very exciting names - things like HD 86081 b, with HD 86081 being the name of the star, and 'b' denoting the second body in that system (the first being the star itself)

talk about pluto. Even though that was a couple of months ago it is still current.

10 planets have been discovered so far. 9 of them have been registered. The 10th one was discovered in 1930 & has been claimed to be larger than pluto & rocky in nature. 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. The object was so far away, however, that its motion was not detected until they reanalyzed the data in January of this year. In the last seven months, the scientists have been studying the planet to better estimate its size and its motions.

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.

It's current name is 2003 UB313.  It is larger than Pluto.\n\nBut is not yet officially recognized as a 'planet'.\n\nThat may change later this year as the International Astronomical Union (IAU) firms up the definition of a planet.\n\nAt that point, it will probably be renamed.  The discoverers of the object have submitted confidential names to the IAU.  Some people call it Xena or Lila, but these are not official names, and are not among the names submitted to the IAU.  \n\nIt is not 'Planet X' ... this is a generic name for a theoretical large planet not yet discovered.  (Pluto was once thought to be 'Planet X', but it is too small.)  The Planet X theory has been disproven.\n\nSedna is a smaller object (smaller than Pluto), and may also be reclassified as a planet ... but I don't think it's likely.\n\nOne thing is for sure though ... Pluto will not lose its classification as a planet ... astronomers are sentimental too.

New planet, discovered by the Samuel Oschin Telescope at the Palomar Observatory near San Diego, Calif., on Jan. 8, 2005,  is yet to be formally named.\n\n(This  newly-discovered object is more distant than the mysterious planetoid SEDNA discovered in 2003. Sedna is designated 2003 VB12.)\n\n Is at least as big as Pluto and about three times farther away from the Sun than Pluto. It is very cold and dark.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. \n\nThis places the new planet more or less in the Kuiper Belt, a dark realm beyond Neptune where thousands of small icy bodies orbit the sun. The planet appears to be typical of Kuiper Belt objects--only much bigger. Its sheer size in relation to the nine known planets means that it can only be classified as a planet itself

An object larger than pluto has been discovered but it will be up to the International Astronomical Union (IAU) to give it official planet status and to name it.

yes.there is entirely a newly discovered solar system.there are 3 planets,all revolving around the star upilisone androemedae,and all of them are bigger than jupiter!and NASA has sent satellites which will go to pluto and beyond.hope we find the answers then!

A new object, 2003 UB303, was discovered in orbit beyond Pluto. It's preliminary name is Lila. There is still debate as to whether or not it is actually a planet or a large asteroid. This is the same as the current debate about Pluto.

2003 UB-313 (tentatively named "Xena") was discovered, or more specifically, confirmed, back in 8-January 2005 and was the first TNO (Trans-Neptunian Object) discovered that was larger than Pluto.  There has been ongoing debate about whether to classify it as a planet or not.  Reciprocally, there is a counter-push claiming that if 2003 UB-313 were to not be classified as a planet, then Pluto should also be removed from the IAU's "official list".\n\nAs of today, though, Pluto is still a planet, and Xena is not.\n\nNeither are 90377 Sedna and 90482 Orcus, two more candidate planetoids.  Though these two are both smaller than Pluto and Xena, they are still of roughly spherical shape and similar composition.

The International Astronomical Union decided that Pluto was no longer a planet.  Instead, they decided to classify it as a "dwarf planet".\n\nSee the details below.\n\nRESOLUTION 5A\nThe IAU therefore resolves that "planets" and other bodies in our Solar System, except satellites, be defined into three distinct categories in the following way:\n\n(1) A "planet" [footnote 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\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) shape [footnote 2] , (c) has not cleared the neighbourhood around its orbit, and (d) is not a satellite.\n\n(3) All other objects [footnote 3] except satellites orbiting the Sun shall be referred to collectively as "Small Solar-System Bodies".\n\n\nFootnote 1: The eight "planets" are: Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, and Neptune.\n\nFootnote 2: An IAU process will be established to assign borderline objects into either dwarf planet and other categories.\n\nFootnote 3: These currently include most of the Solar System asteroids, most Trans-Neptunian Objects (TNOs), comets, and other small bodies.\n\nRESOLUTION 6A\nThe IAU further resolves:\n\nPluto is a "dwarf planet" by the above definition and is recognized as the prototype of a new category of trans-Neptunian objects.

The 10th planet was discovered last summer.\n\nJuly 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. \n\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.

In our galaxy it would be Pluto, but in other galaxies I'm sure its a planet that has never been discovered yet.\n\nEdited to add: No I meant galaxy - as in The Milky Way. I didn't mention the new 'planet' as it hasn't been approved as one yet.\n\nAnd ps next time get the name right! ;)

It is not a planet.  \n\nIt is still classified as a trans-Neptunian object (TNO), even though it appears to be larger than Pluto.  In fact, some people wonder if Pluto is large enough to be considered a planet, but it's unlikely anybody will "downgrade" it.   I heard a lecturer at Berkeley say that Pluto should really be classified as a 'double-planet' with its moon Charon, which is almost half its size.\n\nIn September of this year (2006) the International Astronomical Union (IAU) will come up with a re-definition of how big something has to be to be called a "planet".  E.g. does it have to be large enough to support an atmosphere.  At that time UB313 may become a planet (and get a cool Greek name).

No. There have been a number of objects discovered recently in the outer solar system, including one which appears to be larger than Pluto. But unless something about the size of Neptune is found (which is possible) none of these are likely to gain official planet status.\n\nIn fact, in many respects Pluto should be "demoted," although that is not going to happen.\n\nThere isn't a real scientific definition of where the boundry is between a planet and, say, a moon, or a Kuiper object. For most objects it's clear what to call them, but for others the classification is ambigious. The reason being, of course, that our classifications are (somewhat) arbitrary and the solar system is composed of a continuum of objects of different sizes, in different orbits, etc.\n\nPluto was called a planet when it was discovered because a 9th planet was expected. Percival Lowell spent a long time looking for such a planet which he predicted from orbital irregularities he calculated with Neptune and Uranus. But he never found what he was looking for. Clyde Tombaugh, a couple of years later, resumed the search and eventually discovered Pluto. However, Pluto is much too small and in the wrong place to be Lowell's suspected planet. Lowell was probably just wrong in his calculations.\n\nBecause a 9th planet was expected and because in 1930 little could be told of Pluto's physical characteristics, I don't think anyone seriously doubted whether or not it should be classified as a planet. It seemed obvious, at the time, that it was.\n\nIn the 1950s and 1960s astronmers began to postulate that comets orginated from a vast pool of objects in the extreme distant regions of the solar system. This lead to the hypothesis of the Oort cloud, and the "closer" Kuiper belt (that being 50 - 100 AU from the Sun).\n\nIt wasn't until the 1990s that a lot of Kuiper-esque objects were actually discovered. (I hedge on the classification, because some objects similar in diamter, etc., have been found inside the orbit of Pluto.)\n\nIf in 1930 Clyde Tombaugh had an inkling of something like a Kuiper belt he probably would not have assumed that Pluto was a planet. If Pluto was discovered today it also would (probably) not be considered a planet.\n\nSo basically, if we could re-do history Pluto would be "demoted." On the other hand, there have been generations of kids who learned the whole 9 planets bit. Because of the the International Astronomical Union - the international organization in charge of naming things - has *officially* declared Pluto a planet. A link to their announcement is below.\n\nI suspect - and I am taking an educated guess - that the new objects in the outer solar system, even though slighly larger than Pluto - won't get "official" planet status.\n\nOf course the reality is more complex, and nature doesn't always fit neatly into human classification schemes.
