Not sure how you want this question answered, but here goes:\n\nThe solar system consists of the Sun, the 10 planets, the asteroid belt, The Kuiper belt, and the Oort cloud. The Sun is a main sequence G2 star that contains 99.86% of the system's known mass. Its two largest orbiting bodies, Jupiter and Saturn, account for more than 90% of the remainder; the Oort Cloud might hold a substantial percentage, but as yet its existence is unconfirmed.\n\nIn broad terms, the charted regions of the solar system consist of the Sun and its planetary system: the eight bodies in relatively unique orbits commonly called planets or major planets and two belts of smaller objects, which can be called minor planets, planetoids, meteoroids, or planetesimals. Pluto, the ninth planet, is also considered a member of the outer belt, and its status is currently uncertain, particularly since the discovery of 2003 UB313 (see below). Most objects in orbit round the Sun all lie within the same shallow plane, called the ecliptic plane, and orbit in the same direction. Many are in turn orbited by moons, and the largest are encircled by planetary rings of dust and other particles.\n\nThe major planets are, in order, Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, Neptune, and Pluto. Eight of the nine planets are named after or derived from gods and goddesses from Greco-Roman mythology.\n\nDistances within the solar system are measured most often in astronomical units, or AU. One AU is the mean distance between the Earth and the Sun, or 149 598 000 kilometres. Other units in common use include the gigametre (Gm, one million kilometres) and the terametre (Tm, one billion/milliard kilometres). Pluto is roughly 38 AU (5.9 Tm) from the Sun, while Jupiter lies at roughly 5.2 AU (778 Gm).\n\nUsing radiometric dating, scientists can estimate that the solar system is 4.6 billion years old. The oldest rocks on Earth are approximately 3.9 billion years old. Rocks this old are rare, as the Earth's surface is constantly being reshaped by erosion, vulcanism and plate tectonics. To estimate the age of the solar system scientists must use meteorites, which were formed during the early condensation of the solar nebula. The oldest meteorites (such as the Canyon Diablo meteorite) are found to have an age of 4.6 billion years, hence the solar system must be at least 4.6 billion years old.\n\nThe current theory of solar system formation is the nebular hypothesis, first proposed in 1755 by Immanuel Kant and independently formulated by Pierre-Simon Laplace. The nebular theory has been refined over many years and now has a great deal of evidence supporting it.\n\nTo briefly summarize, the nebular theory holds that the solar system was formed from the gravitational collapse of a gaseous cloud called the solar nebula. It had a diameter of 100 AU and was 2-3 times the mass of the Sun. Over time a disturbance (possibly a nearby supernova) squeezed the nebula, pushing matter inward until gravitational forces overcame the internal gas pressure and it began to collapse. As the nebula collapsed it began to spin faster to conserve angular momentum, and became warmer. As the competing forces associated with gravity, gas pressure, magnetic fields, and rotation acted on it the contracting nebula began to flatten into a spinning protoplanetary disk with a gradually contracting protostar at the center.\n\nGrains of dust (silicates and metals) and ice (hydrogen compounds) condensed from the gas, and began to accrete into larger and larger clumps, forming planetesimals. Inside the frost line, planetesimals were composed of rock and metal, because those are the only grains that can condense at those temperatures, and remained relatively small because they were only 0.6% the mass of the disk. The larger icy planetesimals beyond the frost line became massive enough to capture and hold onto helium and then hydrogen gases, which caused them to rapidly grow into jovian protoplanets.\n\nAft

NINE, I think senda is not the 10th planet (because of its small size). Nine planets are:\n\nMercury(Roman god of thieves)\nVenus(God of beauty)\nEarth\nMars(God of War)\nJupiter(Supreme Roman god)\nSaturn(God of agriculture)\nUranus(Ruler of the heavens, father of the Titans\nNeptune(God of the sea)\nPluto.

The newest planet is Sedna. It could be the 10th planet on our solar system.

Yes there are nine in our solar system, and as someone else mentioned Pluto is not really meeting the requirements to be defined as a planet. But the problem is rewriting the history books which won't happen so they will leave it as a planet... a "historical planet".\n\nIf we are talking about all known planets we have discovered, there are many. Extra solar planets have been found around distant stars for several years now. Not actually seen but found by measuring that planets gravitational pull on it's star. Of course we can't get an accurate count of all planets in the universe but we can use the "Drake Equation" to get a good idea.\n\nThe Drake Equation is:\n\nN = N* fp ne fl fi fc fL\n\nN* represents the number of stars in the Milky Way Galaxy \nAnswer: Current estimates are 100 billion.\n \nfp is the fraction of stars that have planets around them \nAnswer: Current estimates range from 20% to 50%.\n\nForget about the rest of the equation because it doesn't apply (looking for intelligent life)\nKeep in mind this equation is for our galaxy. They estimate 100 billion Galaxy's in our Universe (not to mention other planets that exist in other dimensions that we have discovered as a result of trying to solve the "unified theory" of everything) so…\n\nYou do the math!!!

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

According to the authority of the IAU, there are nine planets in our solar system. In increasing distance from the Sun they are (with the astronomical symbol in brackets):\n\nMercury (☿) \nVenus (♀) \nEarth (♁) with one confirmed natural satellite, Luna (the Moon) \nMars (♂) with two confirmed natural satellites, Phobos and Deimos \nJupiter (♃) with sixty-three confirmed natural satellites \nSaturn (♄) with forty-six confirmed natural satellites \nUranus () with twenty-seven confirmed natural satellites \nNeptune (♆) with thirteen confirmed natural satellites \nPluto (♇) with three confirmed natural satellites, Charon, S/2005 P 1 and S/2005 P 2 \nHowever, there is some pressure for Pluto to be reclassified as a Kuiper Belt object, especially in light of the discovery of 2003 UB313. This object, however, has not yet received a definitive classification from the IAU.\n\nSedna was widely touted as a planet when it was discovered in 2003, as it was the largest object found since Pluto. However, mainly due to its size still being smaller than Pluto's, it did not achieve planetary status from the IAU. However, the discovery in 2005 of 2003 UB313 (nicknamed Xena), with a size and mass larger than Pluto seems to have forced the issue. As of January 2006 it has not yet been accepted as a planet, but the IAU is expected to announce a definition of a planet soon, which will likely either see 2003 UB313 become a planet, or have Pluto stripped of its status.

There are more stars than we can count.  Most of them have planets.   Most of those planets have moons.

There are ten planets in our solar system namely mercury,venus,earth mars,jupiter,saturn,uranus,neptune,pluto\nand\n2003-UB313 is the official name of the object that is considered to be a contender for the title of "10th planet". As of August 1st, 2005 the IAU has yet to confirm whether this object will be officially be recognized as the 10th planet in our solar system. This little page will follow events and provide more information when available.\nOfficial Name:  2003 UB313  \nProposed Name:  Unknown\nThe name Xena is rumored to be the name submitted to the IAU for approval, althought there is no official confirmation of the name. "..that was our tongue-in-cheek internal name, never intended for public consumption," says Professor Brown \nDiscovered By: Michael Brown, professor of planetary astronomy at California Institute of Technology (Caltech) and colleagues Chad Trujillo of the Gemini Observatory and David Rabinowitz of Yale University.\n\nFirst photographed in 2003 using a 122cm telescope at the Palomar Observatory. \n \nEstimated Size:  approx 2700 km (1,700 miles) in diameter\nThis is the estimate as of August, 2005. From Wikipedia - Although the object's diameter is not yet well determined, it is estimated to be between 2,390 and 3,550  km . The amount of light it reflects (its albedo ) seems to be quite high, and initial observations show that methane ice is present on the object's surface. Both these properties make it more similar to Pluto than previously discovered large outer solar system planetoids .  \nOrbit: 560 years \nestimated one solar orbit per 560 years.  \nDistance from Sun:\n approx 9 billion miles / 14.4 billion km\nThis is around 100 times the Earth's distance, or 3 times Pluto's distance from the Sun. \nWhere is it Now?  At present, it is near its farthest point from Earth, but in about 280 years, it will be as close as Neptune, (the eighth planet, discovered in 1846).
