What is the name for the newly discovered planet?
150912
The newly discovered planet that rotates our sun is called 2003 UB313, but this question is causing a stir because since theres so many objects that are the size of pluto that rotate our sun scientists are trying to define what the term "planet" exactly means.\nfor more information look at the website below from "NASA"

(Vulcan- no longer there, refer to first article), Mercury, Venus, Earth, Mars, (Minerva- another defunc planet now an asteroid belt), Jupiter, Saturn, Uranus, Neptune, Pluto and tenth planet.\n\nI believe the 10th planet(Planet X) is temporarily called Xena, and its moon(let) Gabrielle. I don't know when the Astronomy Body of Scientists responsible for naming the heavenly bodies will formally announce the name and nature of the planet as, up to now, they are even questioning if it is a planet or merely an overly large asteroid.

They discover new planets in the universe everyday. But 10th planet in our solar system has been discovered. It has been couple of months, though. You can read more here: http://www.nasa.gov/home/hqnews/2005/jul/HQ_05209_10th_Planet.html

The most recent planet discovered in our our solar system is named Cedna after the Inuit goddess of the sea. It is even smaller than Pluto.

According to NASA's Planet Quest Atlas, most of the the extrasolar planets are labeled as the name of the star followed by 'b' for the first planet, 'c' for the second, etc.\n\nFor example:  The planet found around the star HD 102195 is called HD 102195 b.

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:)

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.

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.

Yes there is a tenth planet out there but they haven't named it yet, all we know is that its a kuiper belt object, and larger than pluto

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! ;)

Venus.\n\nAnd since no one else is citing an authoritative source:\n\nhttp://antwrp.gsfc.nasa.gov/apod/ap950815.html\n\n" Venus: Earth's Sister Planet"

My guess would be Pluto

Often many people get involved in discovering a "planet" as several observations are required to verify and calculate the orbit.  Exactly what a planet is is subject to debate as even Pluto is not completely accepted as one.  The debate includes the question "how big does a rock have to be for us to call it a planet as opposed to an asteroid?"  Planet X was one possibility that seemed to just fade out of the news.  "Buffy" is the nickname of the latest "unusual" object out there (see my source article).  Heheheh, yes, "Xena" came public a few days before "Buffy."  Both are among the many rocks in the Kuiper Belt, including Pluto.  NASA's launching a probe called "New Horizons" to check out Pluto and the Kuiper Belt.

Pluto is officially a planet. Although if it were discovered today it would almost certainly NOT get planet status.\n\nBecause of all the confusion with the recent spate of Kuiper Belt Objects, the International Astronomical Union (they are in charge of naming stuff) declared Pluto a planet for historical reasons.\n\nOf course, for astronomical research it doesn't matter too much what you call it...

UB313, the 10th "planet" that is said to be bigger than Pluto.\n\nI'm not lying, read all the sources.\nBTW, the CNN news which adds support to the discovered planet is dated February 2, 2006.

The new things they discovered are Sedna and Quaoar. So there could be 11 planets\nThe planet Quaoar  is the 11th  planet in the meridian solar system . Its orbit is different than the other planets in our solar system.  The surface of Quaoar is barren it consists mainly of hard rock and ice there is a light atmosphere around the planet Quaoar but it's not fit for humans. There are no life forms on the surface of Quaoar it is a dead planet and you could say the planet Quaoar is a large rock trapped in the darkness of the Kuiper belt in a orbit around our sun. \n\nThe planet Sedna is the second most reddish planetary body in the Solar System, after Mars. Although inclined by only around 11.9 degrees from the ecliptic where the eight major planets orbit, Sedna's distant orbit is extremely elliptical indicating that its formation and orbit may have been influenced by by a passing nearby star during the early years of the Solar System, when Sol formed out of a molecular cloud with many other closeby stars around 4.6 billion years ago. There is indirect evidence (an unexpectedly slow 40-day rotation) that Sedna has its own moon, which astronomers hope to confirm with the Hubble Space Telescope (more information and images from NASA. The icy object will move closer to the Sun over the next 72 years -- to 76 AUs of Sol -- before receding back towards the inner Oort Cloud. \n\nThis is about their discoveries: http://science.nasa.gov/headlines/y2005/29jul_planetx.htm\nhttp://news.bbc.co.uk/2/hi/science/nature/3511678.stm
