Titan is smaller than Mars. There are no moons in the solar system that are as big as Mars. Ganymede is the biggest out of Jupiter's moons (Callisto is second) and also in the solar system. Titan is the second biggest moon in the solar system, and Callisto is third. Ganymede and Titan are the only moons in the solar system that are bigger than Mercury. Callisto is slightly smaller. I hope this helps.

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

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.

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.

The largest "planet" by mass currently known is HD 168443 c, which orbits the star HD 168443, a sunlike star located 123.5 light years from our own solar system. HD 168443 c orbits its star at a distance of 2.87 AU (430.5 million km) and completes one orbit of its star every 1739.5 days. Its mass is known to be at least 17.1 times that of Jupiter, and is suspected to be 34 times that of Jupiter (there is, as you can see, a lot of uncertainty in the measurment). This means that technically, it's considered a small brown dwarf rather than a planet, although the distinction is somewhat academic.\n\nP.S. it's Jupiter, not Jupitar.

Jupiter is just the largest planet in our solar system-that's like saying uncle Joe in the largest person who ever lived, cause he is the largest person in the family!  We have already identified over a dozen planets much larger than Jupiter in other solar systems.  We havent even identified all the galaxies in the universe (each of which contains around 100 billion stars, each star of which may contain 10 or so planets), let alone seen all the planets there are..

There is no actual picture of the entire solar system. If one could be made, it is very unlikely that you would be able to see all the planets. I am sure you would only see The gas giants Jupiter and Saturn - as dots; maybe you will see Neptune and Uranus, that is about it. From earth if you look at Jupiter in the night sky it is as big as a star - though one of the brightest objects in night sky. From a position where you could see all the planets (the solar system is bigger than that, but let us restrict ourselves to only Pluto's orbit) you would see it as much smaller. Jupiter is 1,600 times bigger than earth (volume). Sun is a million times bigger. From most cities you can see Mars, Saturn, Jupiter and Venus. From a position where you could take a picture of all the planets you wont see all of them.\n\nEDIT: btw, I just remember I was talking about visibility of sun and planets. Actually if a photograph were taken jupiter and sun will be visible. The Sun is a star it will be visible not due to its size but due to the amount of light it gives. If we plotted it on a graph based only on its size and not its luminosity, it will be as visible as anything on the graph and no more. So if we drew an illustration 1024 pixels wide (most 17 inch computer screens are 1024x768 pixels) and put sun on the left most pixel and Neptune on the right most pixel - none of them will be visible. The distance between sun and earth is 1 AU (1 astronomical unit). Sun's Diameter is 1/150 AU, Neptune is 30 AU away from sun. If we scale 30AU to a 1024 pixel screen every pixel is equal to 0.029 AU, anything smaller than 0.029 AU can not be represented on this screen, the sun is 0.006AU wide - 1/5th of a pixel. If you open MS Paint and put a dot with a pencil that is one pixel imagine 1/5th of that - that is sun's size scalled to a 1024x768 screen.\n\nAnyway, Cronides' second link is the answer you are looking for.

Pluto is the farthest planet from the sun. Its average distance from the sun is 3,670,050,000 miles (5,906,380,000 kilometers).

Saturn is the sixth planet from the Sun and the second-largest planet in our solar system. Only Jupiter is larger. In spite of it's giant size, though, Saturn doesn't weigh very much. In fact, as a whole,Saturn is lighter than water and would float in a bathtub if you had one big enough (of course the water bill would be extremely high).

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.

Jupiter is the largest planet in the solar system. Its diameter is 88,846 miles (142,984 kilometers), more than 11 times that of Earth, and about one-tenth that of the sun. It would take more than 1,000 Earths to fill up the volume of the giant planet. When viewed from Earth, Jupiter appears brighter than most stars. It is usually the second brightest planet -- after Venus.\n\nJupiter is the fifth planet from the sun. Its mean (average) distance from the sun is about 483,780,000 miles (778,570,000 kilometers), more than five times Earth's distance. Ancient astronomers named Jupiter after the king of the Roman gods.\n\nAstronomers have studied Jupiter with telescopes based on Earth and aboard artificial satellites in orbit around Earth. In addition, the United States has sent six space probes (crewless exploratory craft) to Jupiter.\n\nAstronomers witnessed a spectacular event in July 1994, when 21 fragments of a comet named Shoemaker-Levy 9 crashed into Jupiter's atmosphere. The impacts caused tremendous explosions, some scattering debris over areas larger than the diameter of Earth.\n\nPhysical features of Jupiter\n\nJupiter is a giant ball of gas and liquid with little, if any, solid surface. Instead, the planet's surface is composed of dense red, brown, yellow, and white clouds. The clouds are arranged in light-colored areas called zones and darker regions called belts that circle the planet parallel to the equator.\n\nOrbit and rotation\n\nJupiter travels around the sun in a slightly elliptical (oval-shaped) orbit. The planet completes one orbit in 4,333 Earth days, or almost 12 Earth years.\n\nAs Jupiter orbits the sun, the planet rotates on its axis, an imaginary line through its center. The axis is tilted about 3¡. Scientists measure tilt relative to a line at a right angle to the orbital plane, an imaginary surface touching all points of the orbit.\n\nJupiter rotates faster than any other planet. It takes 9 hours 56 minutes to spin around once on its axis, compared with 24 hours for Earth. Scientists cannot measure the rotation of the interior of the giant planet directly, so they have calculated the speed from indirect measurements. They first calculated the speed using an average of the speeds of the visible clouds that move with interior currents, except for a more rapid zone near the equator.\n\nJupiter sends out radio waves strong enough to be picked up by radio telescopes on Earth. Scientists now measure these waves to calculate Jupiter's rotational speed. The strength of the waves varies under the influence of Jupiter's magnetic field in a pattern that repeats every 9 hours 56 minutes. Because the magnetic field originates in Jupiter's core, this variation shows how fast the plant's interior spins.\n\nJupiter's rapid rotation makes it bulge at the equator and flatten at the poles. The planet's diameter is about 7 percent larger at the equator than at the poles.\n\nMass and density\n\nJupiter is heavier than any other planet. Its mass (quantity of matter) is 318 times larger than that of Earth. Although Jupiter has a large mass, it has a relatively low density. Its density averages 1.33 grams per cubic centimeter, slightly more than the density of water. The density of Jupiter is about 1/4 that of Earth. Because of Jupiter's low density, astronomers believe that the planet consists primarily of hydrogen and helium, the lightest elements. Earth, on the other hand, is made up chiefly of metals and rock. Jupiter's mix of chemical elements resembles that of the sun, rather than that of Earth.\n\nJupiter may have a core made up of heavy elements. The core may be of about the same chemical composition as Earth, but 20 or 30 times more massive.\n\nThe force of gravity at the surface of Jupiter is up to 2.4 times stronger than on Earth. Thus, an object that weighs 100 pounds on Earth would weigh as much as 240 pounds on Jupiter.\n\nThe atmosphere of Jupiter is composed of abou
