Did they really find a new planet in the universe called ub 313?

Yes. It's actually in our own solar system.  Whether it is a planet or not is the real question.  It is really small.  While bigger than pluto, it is still smaller than the Earth's moon!

A 10th planet has recently been found in our Solar System. It's designation right now is UB313. Check out the following website for more information:\n\nhttp://channels.isp.netscape.com/news/story.jsp?idq=/ff/story/0001/20060201/1301968801.htm&ewp=ewp_news_0106planet&floc=NI-slot1a

maybe you wanted to write 10th planet, not 11th planet.\n\nmaybe there was such a thing but i don't see any records of it on nasa-s site.\n\nWhat i do see is the report of the 10-th planet being discovered, maybe that's what u  were reffering to.\n\nhere's the link\n\nhttp://science.nasa.gov/headlines/y2005/29jul_planetx.htm

Possibly, as scientists have yet to make up their mind. One particular object, originally found in 2003 but confirmed two years later by Mike Brown (Caltech), David Rabinowitz (Yale University), and Chad Trujillo (Gemini Observatory), has renewed the old debate about what constitutes a planet since it is at least 5% larger than Pluto with an estimated diameter of 2400 km . It currently has no name, but has been given the provisional designation 2003 UB313, and has been nicknamed "Xena" by its discoverers, after the television character. It has many similarities with Pluto: its orbit is highly eccentric, with a perihelion of 38.2 AU (roughly Pluto's distance from the Sun) and an aphelion of 97.6 AU, and is steeply inclined to the ecliptic plane, at 44 degrees, more so than any known object in the solar system except the newly-discovered object 2004 XR190. Like Pluto, it is believed to consist mainly of rock and ice, and has a moon . Whether it and the largest Kuiper belt objects should be considered planets or whether instead Pluto should be reclassified as a minor planet has not yet been resolved.

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).

Actually, you're all wrong.  It's 2003 UB313 the recently discovered 10th planet which has not yet been given a perminent name.  As of July, 2005, the planet 2003 UB313 was approximately 97 AU from the sun, over twice the distance between the sun and Pluto (40 AU).\n\nIf you're actually wondering about the 2nd farthes planet (which may be the case as most people don't know about 2003 UB313), most of the time (including the present) it's Pluto, but Pluto has a crazy eliptical orbit (one of the reasons its status as a planet is debatable), and sometimes crosses paths with Neptune.  When I learned the order of the planets in 2nd grade, Neptune was farther away than Pluto, so instead of "my very educated mother just served us nine pizzas," we learned "my very educated mother just served us pistachio nuts."

When I was in school, there was 9.  \n\nMercury\nVenus\nEarth\nMars\nJupiter\nSaturn\nUranus \nNeptune\nPluto\n\nNow, there has been another "planet" found.  I am not sure if they have classified it as a planet in our solar system just yet.

Largest known to date is the "puffy planet" HAT-P-1b orbiting the sunlike star ADS 16402 B, one of a binary pair of G0 V stars 450 light yeard away, in the constellation Lacerta. Our sun is of spectral class G2 V i.e. a little cooler than ADS 16402 B.\n\nHAT-P-1b has a radius of 1.36 x the radius of Jupiter. \n\nIt was discovered on 13 September 2006 and is 450 light years away. It has the lowest density of any known extrasolar planet. It also has the name Krais.\n\nIt was announced as follows:\n\n"Using small automated telescopes in Arizona and Hawaii, the HATNet project has detected an object transiting one member of the double star system ADS 16402 AB. This system is a pair of G0 main-sequence stars with age about 3 billion years, at a distance of ~139 parsecs and projected separation of ~1550 AU. The transit signal has a period of 4.46529 days."\n\nNote: Only the radii of transiting planets are known.

no the fourth planet from the sun.put me on best answer please!\n\nHappy Trails ♥!

Not yet. They are still arguing about it. They may decide to call these new objects planets, or they may demote Pluto to a KBO, or they may just keep arguing.

Astronomers say they have discovered what appears to be an entirely new kind of planet, an extra-large gas giant unlike any known world in our solar system or beyond. \n\n"This questions our understanding of how giant planets are formed and evolve," said Robert Noyes, a senior physicist at the Harvard-Smithsonian Center for Astrophysics (CfA). \n\n\nThe planet, dubbed HAT-P-1, is located some 450 light-years from Earth in the constellation Lacerta. \n\nIt is the largest planet ever discovered and boasts a radius nearly 1.4 times larger than Jupiter's. \n\nHAT-P-1 is also the least dense of all known planets. \n\n"This planet is about one quarter the density of water," said Gaspar Bakos, a Hubble fellow at CfA. \n\n"In other words, it's lighter than a giant ball of cork. Just like Saturn, it would float in a bathtub if you could find a tub big enough to hold it, but it would float almost three times higher." \n\nUnlike more familiar gas giants, including those in our solar system, HAT-P-1 does not appear to have a solid core.

First of all, it is not galaxy you are talking about, it is solar system. Secondly, a lot of people here are saying why ask such a stupid question. What most of them probably don't know is that while pluto is the smallest of our "officially classified" planets it has come to light in recent months that we may have more planets. \n\nThe debate has been raging on in the space exploration community that recently discovered bodies past pluto may actually be planets in our system as well. They are also saying they may take pluto off the official planet list because it is looking more and more like a captured asteroid compared to these new planets.\n\nFor those who want to read more about these new planets, do a search for the planet Xena (which is the temporary code name for the new planet). \n\nIn short, Pluto is "currently" the right answer but if it is removed from the list, then mercury will be the smallest planet.\n\nHope this helps!

There are actually several "planet like" objects beyond Pluto in an area called the Kuiper belt that contains thousands of objects that circle the sun.\n\nAt present none of them have been officially recognized as new planets. \nThe discovery of these new planet size objects including  2003 UB313 (nicknamed XENA), Sedna(in 2004) and Quaoar(in 2002 by the same team) have triggered a re-evaluation of the necessary criteria to call something a planet.\n\nIt is likely that this team at Caltech will  discover other objects to be added to the list of potential "planets" in our solar system.\n\n2003 UB313(nicknamed XENA unofficially) is larger than Pluto which leaves officials in a bit of dilemna.  How can they recognize Pluto as a planet and not this object?

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.

I think youd see a new planet ;)

we already found a 10th planet in our solar system, but it's still unclear if it's considered as planet (some say it is too small).\nThe name of the "10th planet" is Sedna.
