Jupiter as of now has 63 recognised moons.  Dr. Scott Shepard maintains a wonderfull webpage detailing all of them, their names, physical data and discovery.  Rather than just copying and pasting a large block of text I recomend that you check out his web page for all the info you request.

http://home.case.edu/~sjr16/jupiter_moons.html These are the four Galilean satellites. They are named so because they were the only four moons that Galileo was able to see. They are also the largest of Jupiter's moons. From top-left in a clock-wise direction, they are Ganymede, Callisto, Europa, and Io.\n\nIf Ganymede were not bound to Jupiter, it would be considered a planet in its own right. It is actually bigger than Mercury, being 390 km (234 miles) larger in diameter. It has heavily cratered dark regions, with lighter expanses in-between. Geologists think that it used to have plates, like the Earth, but they froze together soon after Ganymede's birth.\n\nCallisto, the outermost of the Galilean moons, is almost an exact twin of Mercury in size and appearance. Every square mile is covered with craters or other signs of bombardment. Other than that, there are no distinct characteristics\n\nEuropa, closer to Jupiter than Ganymede, is the smoothest natural body in the solar system. It resembles a billiard ball until seen very close-up. At that distance you can start to see dark, deep, and narrow cracks. In scale, though, the relief is no bigger than a line on a billiard ball made with a felt-tipped marker. Geologists think that Europa has liquid water underneath the icy surface - and possibly life.\n\nIo, closer yet, is commonly compared to a pizza. Its volcanoes make it the most active world in the solar system. They spew out the sulfuric acid that gives Io its many colors. They also make Io one of the only three moons with an atmosphere in the solar system. Saturn's Titan and Neptune's Triton are the other two moons. Io is similar in size and composition to our moon. Io is caught in the middle of a tug-of-war between Jupiter and the other moons. Tension has melted the interior and raised the surface temperatures so high that scientists calculated that it generates the most heat for its size of any body in the solar system, except for the sun.\n\nOther Moons\n\nThere are 57 other moons that have been discovered around Jupiter. There are four closer than Io. Their names, in order from Jupiter are Metis, Adrastea, Amalthea, and Thebe. Still in order after the Galilean Satellites are recently discovered Themisto, Leda, Himalia, Lysithea, and Elara. Then there are four more recently discovered moons, Ananke, and three more moons, of which scientists know little about. After these seven come Ananke, Carme, Pasiphaë, and Sinope, with two more moons in-between Pasiphaë and Sinope. After Sinope, 12 more moons are found.\n\nThe outer 33 moons all orbit Jupiter in a direction opposite (except for J/2003 J20) to that which Jupiter spins, which leads scientists to believe they are captured asteroids.\n\nThe largest non-Galilean moon is Amalthea, being 262 km (163 miles) at its widest diameter.\n\nThe innermost two moons, Metis and Adrastea, patrol the outer edge of the rings, their small gravity being enough to keep the particles from flying out.\n\nNearly all of the moons that have been discovered in the last few years orbit retrograde to the direction of Jupiter's rotation , indicating that they are most likely not native to the system. They are also very small. Those that have not yet been given names will eventually be given names by the International Astronomical Union, the only official naming group.

There are 9 bodies in our solar system officially recognized as "planets" by the International Astronomical Union (IAU).\n\nThere are a number of large bodies, such as asteroid Ceres (between Mars and Jupiter), and Sedna (way out beyond the Kuiper Belt) that are considered candidates, but are unlikely to ever be recognized as planets.  Pluto is sometimes considered too small to be called a planet, but just for historical reasons, the IAU is unlikely ever to "downgrade" it.  \n\nIn 2003 a large body was discovered outside the orbit of Neptune, currently called UB313, and appears to be larger than Pluto.  The IAU is reviewing the definition of "planet" and is scheduled to make a decision in September of this year (2006) as to whether UB313 is officially the 10th planet.  Hopefully then they will give it a cool Greek name. :-)

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

Designated 2003 UB313 (it hasn’t been officially named yet), this “planet” is slightly larger than Pluto, has a small moon and takes more than 500 Earth years to orbit the Sun.\nA planet is a body large enough that, when it formed, it condensed under its own gravity to be shaped like a sphere. It orbits a star directly and is not a moon of another planet.\n To simplify things, some scientists propose that the size of Pluto be designated the smallest size for a planet. If that argument carries the day, we now have 10 planets, since 2003 UB313 meets all the criteria.

Well it sounds like they all have their very own opinion. I found this wonderful site, it is trust worthy ... it's an on line encyclopedia and was just updated May 30th.\n    Jupiter has at least 63 natural satellites (also called moons!) \n    Saturn has a large number of moons, however no one will ever be certain of the precise number because the floating chunks of ice in Saturn's rings technically count as moons and it is difficult to draw a distinction between a large ring particle and a moon. One cool thing about Saturn is that it has the moon named Titan, which you have probably heard of because it is the only moon in our solar system that has a dense atmosphere. \n   If you decide to check out this site, just scroll down and click on the planet of your choice and it will take you to all the info on that planet, then click on natural satellites. Best of luck to you and search for the truth about these moons!

There's really only one 'icy planet', and that's Pluto.  Mercury, Venus, Earth, and Mars are all terrestrial planets, while Jupiter, Saturn, Uranus, and Neptune are all jovian.  That leaves Pluto, and maybe that new one if they decide to call it a planet.

I assume that the question is How many planets do not HAVE moons. If that is the case, then the answer is 2, Mercury and Venus. All of the other planets have at least one moon.

52 Europa, diameter 289 km, was discovered on February 4, 1858 by H. Goldschmidt. It is named after Europa, one of Zeus's conquests in Greek mythology.\n\nEuropa may be the seventh largest known asteroid (it cannot currently be ranked relative to 3 Juno) and is very dark in color. It belongs to the Hygiea asteroid family.\n\nIt should not be confused with Jupiter's moon Europa.\n\nNasa is preparing plans for a possible mission to Europa ( the MOON) that would put a lander on the surface. It has even been suggested that a mission could be devised that would drill through the ice layer and release a probe into the liquid underment. This is the "hydrobot" concept.\n\nWater or ice? Liquid or slushy or frozen solid? Ever since the Voyager spacecraft missions flew through the Jupiter system in 1979, planetary scientists have wondered about the layer of ice surrounding the second moon of Jupiter.\n\nEuropa's ice surface makes it one of the brightest, and smoothest, objects in our solar system.\n\nRecent Galileo spacecraft images have provided evidence that Europa had a liquid ocean underneath the frozen crust sometime in its history, but it is not clear if this ocean still exists. Of the various explanations proposed by scientists, most scenarios of Europa's evolution have the water layer freezing solid earlier in its history. The moon's surface is -260° F, which could freeze an ocean over several million years. But scientists think that the warming caused by a tidal tug of war with Jupiter and neighboring moons could be keeping large parts of the ocean liquid.

Jupiter is definitely a planet, a gas giant type. Sometimes the Jovian system - the huge planet with its moons, taking their number and size of the largest ones, is referred to "LIKE a mini solar system". Jupiter is not a star though, and it is not a brown dwarf. Though Jupiter has a major gas atmosphere it still has a metallic core. A browm dwarf, an intermidiary between a star and planet, is totally made of gas, so there is a full convection between its outer and inner layers, unlike Jupiter.
