what's name of  10th  planet?
89889
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

Our own solar system has 10 planets that we know of:\nMercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, Neptune, Pluto, and the newly discovered 2003 UB313.  That last one is still being contended, and why that debate gets so heated is beyond me.\n\nThere are actually 155 known extrasolar planets, and that number is only going to rapidly increase.  You can find a list on the California & Carnegie Planet Search site below:

Pluto - 1930.\n\nPluto is still considered a planet and all the objects that Mike Brown et.al. have been finding (Sedna, 2003UB313, etc.) have not been granted planetary status, no matter how often Mike Brown says that 2003UB313 is a planet, quite simply it is not.\n\nThe IAU's Division of Planetary Science is currently working on the whole planet issue, and we are supposed to have some sort of resolution to this issue by august of this year.  Right now it seems that we are leaning to either strip Pluto of its planetary status, through making an actually definition of the word "planet," or to make Pluto the arbitrary cut-off line.  This would mean that 2003UB313 would become the 10th planet, but Sedna (being smaller than Pluto) would not.\n\nAs of right now there is no official motion in place to remove planetary status from pluto, although it may loose it through the adoption of a new definition of what a planet is.\n\nAlso, no matter how catchy the name sounds, or how often the BBC calls it that, the official name of 2003UB313 will not be "Xena," that was simply Brown's code name for that object.

Currently, we have discovered 10 planets (Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, Neptune, Pluto, and Sedna), but there are smaller planets called transneptunian objects that are very small and cannot be detected by current technology. Carla is probably a transneptunian object.

no there is no 10th planet.\n\nwell scientists argue that pluto is small and should not be called a planet.\n\nso when they discovered Sedna( the 10th planet), it was smaller than pluto and so was considered as a mini planet.

Over 2 years ago, scientists DID find a 10th planet beyond Pluto, and it's even larger than Pluto. The planet is a typical member of the Kuiper belt, but its sheer size in relation to the nine known planets means that it can only be classified as a planet. Currently about 97 times further from the sun than the Earth, the planet is the farthest-known object in the solar system, and the third brightest of the Kuiper belt objects. \n\nFor images and info, check the NASA web site: http://www.nasa.gov/vision/universe/solarsystem/newplanet-072905.html

THere is an argument among astromoners as to whether classify the bodies beyond pluto as planets... consider that in the asteroid belt there are many objects orbiting the sun... do we call them all planets?\n\nCurrently there are officially only 9 planets:\nMercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, Neptune, and Pluto.

10 planets dont forget xena

Sol (our solar system) consists of 9 planets, over 140 moons (to date) and several small cosmic objects (comets and asteroids).\n\nMercury (0 moons)\nVenus (0 moons)\nEarth (1 moon)\nMars (2 moons)\nJupiter (63 moons as of 2004)\nSaturn (34 moons)\nUranus (21 named moons, 6 unnamed moons)\nNeptune (8 named moons, 5 unnamed moons)\nPluto (1 moon)\n\nThere have been discoveries of more "planetary objects" beyond Pluto, but they have not been declared to be planets in the same sense as the others.

The nine planets are Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, Neptune(sometimes Pluto), and Pluto(sometimes Neptune).

Nine in our solar system - Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, Neptune, Pluto.

The tenth planet is like really great, thanks for asking.  He spins around and around and makes one revolution around the sun about once every several thousand thousand years.  Therefore you might call this tenth planet (he doesn't mind) a chunk of ice, and not really planet-like at all.  But wait, you're saying, Pluto is a chunk of ice and also a planet!  Well, Pluto actually (he's telling me now) doesn't even consider himself a planet, as he's really just a large ice-chunk in the Kuiper Belt.  The tenth planet (we'll call him "Frank", that's what he prefers) is a little peeved that Pluto gets a thousand-brother belt to wear and all he's got is the occasional through-comet.  We can't help you, Frank, I'm sorry.  We're like, a billion miles away.

My favorite planet is the 10th planet, 2003 UB313, discovered to be larger than Pluto last year, and is also known as "Xena". (If you think im full of it read up on it yourself)

8 - Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, and Neptune.  Almost assurdly there are no more big ones.  There are also a class of planets called "dwarf planets", including Pluto and a couple of others.

Well, there's nine so far - Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, Neptune, and Pluto.  However, scientists have discovered other planets that orbit our Sun that are even further out than Pluto!  So there's a possibility that we may update our information involving the solar system sometime in the future....

In the last few years, there have been three bodies each reported as being a new tenth planet. Their provisional names are: 50000 Quaoar, 90377 Sedna and 2003 UB313.\n\nEach time a new planetoid discovery is named, it reignites discussion on whether Pluto itself, currently considered the solar system's ninth planet, is truly a planet at all.\n\nIn fiction, tenth planets are quite common: one of the most famous was created for the British television science fiction series, Doctor Who, in 1966. In that story, the tenth planet was Mondas, originally a sister planet to Earth, which somehow left our solar system for a while. To survive, the humans on the planet started replacing their body parts with cybernetics -- over time turning the whole planet's population into Cybermen.

None, but there are nine planets in the solar system that Earth is part of.
