Our solar system now has eight planets: Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus and Neptune.\nThey are arranged outward from the sun as I've listed them.\nThat is with Mercury closest to the sun.\n\nWe also have three "Dwarf Planets"\nCeres, Pluto, and Eris.\nCeres being closest to the sun.

The size wise order of the planets in our Solar system is as follows:-\n1) Jupiter, 2) Saturn,3) Uranus or Herschel,4) Neptune\n5) Earth, 6) Venus, 7)Mars,8)Mercury,9)Pluto.\nThe largest is Jupiter and the smallest is Pluto. Our moon is a natural satellite of the earth and not an independent planet. It is smaller than Pluto.

Pluto is estimated to have a radius that is no more than 1200 km.\n\nMoons in the solar system that are larger than this organized by planet:\n\nEarth - Moon (1738 km)\nJupiter - Io (1815 km)  \nJupiter - Europa (1570 km)  \nJupiter - Ganymede (2630 km)  \nJupiter - Callisto (2400 km)\nSaturn - Titan (2575 km)\nSaturn - Triton (1350 km)\n\nJust for comparison the largest asteroid in the solar system is Ceres (466 km).\n\nAlso Ganymede and Titan are larger than Mercury (2440 km).

There is only one solar system, and it is the one our planet is part of.\n\nThe solar system comprises the Earth's Sun and the retinue of celestial objects gravitationally bound to it. Traditionally, this is said to consist of the Sun, nine planets and their 158 currently known moons; however, a large number of other objects, including asteroids, meteoroids, planetoids, comets, and interplanetary dust, orbit the Sun as well. Astornomers are debating over the presence of a tenth planet.\n\nAlthough the term "solar system" is frequently applied to other star systems and the planetary systems which may comprise them, it should strictly refer to Earth's system specifically: the word "solar" is derived from the Sun's Latin name, Sol, and thus the term sometimes appears as Solar System. When talking about another stellar system or planetary system, including the stars and bodies associated with them through gravity, it is usual to shorten it to drop the term "stellar" and form names such as "the Alpha Centauri system" or "the 51 Pegasi system".

Since the diameter of the sun is 864,000 miles and the diameter of a typical basketball is about 9½ inches (they vary from 9¼ to 9½ inches), if we divide 864,000 miles by 9½ inches, we discover that in our model 1 inch represents roughly 91,000 miles. To see how everything else fits into our model we need only divide any other dimensions of our solar system by 91,000. For example, Mercury, on the average, is about 36,250,000 miles from the sun. If we divide 36,250,000 by 91,000 we find that in our model it is roughly 398 inches-or about 33 feet away from the basketball. And, if we divide Mercury' s diameter of 3050 miles by 91,000, we find that the Mercury in our model is just .034 inches wide-about 1/30 inch. This is smaller than a typical BB. \n\nIf you know your stride (mine is about 2½ feet) you can put the basketball on the ground and pace this off. Better yet, if you have access to a football field at a local high school or college, place a basketball on one of the goal lines and walk out to the 11 yard line. This is where Mercury is.\n\nScientists believe that the solar system was formed when a cloud of gas and dust in space was disturbed, maybe by the explosion of a nearby star (called a supernova). This explosion made waves in space which squeezed the cloud of gas and dust. Squeezing made the cloud start to collapse, as gravity pulled the gas and dust together, forming a solar nebula. Just like a dancer that spins faster as she pulls in her arms, the cloud began to spin as it collapsed. Eventually, the cloud grew hotter and denser in the center, with a disk of gas and dust surrounding it that was hot in the center but cool at the edges. As the disk got thinner and thinner, particles began to stick together and form clumps. Some clumps got bigger, as particles and small clumps stuck to them, eventually forming planets or moons . Near the center of the cloud, where planets like Earth formed, only rocky material could stand the great heat. Icy matter settled in the outer regions of the disk along with rocky material, where the giant planets like Jupiter formed. As the cloud continued to fall in, the center eventually got so hot that it became a star, the Sun, and blew most of the gas and dust of the new solar system with a strong stellar wind. By studying meteorites, which are thought to be left over from this early phase of the solar system, scientists have found that the solar system is about 4,600 million years old!

I suppose your question is: "The heaviest natural satellite of our stellar system?"\n\nThe answer:\nAstronomers declare that Ganymede, Jupiter's main galilean satellite, is the largest & the heaviest natural satellite in the Solar System, with a diameter of 5,268 km (3,273 miles). \nGanymede is larger than the planet Mercury.\n\n:-)

The Milky Way is the galaxy which is the home of our Solar System together with at least 200 billion other stars (more recent estimates have given numbers around 400 billion) and their planets, and thousands of clusters and nebulae.\nAs a galaxy, the Milky Way is actually a giant, as its mass is probably between 750 billion and one trillion solar masses, and its diameter is about 100,000 light years. Radio astronomial investigations of the distribution of hydrogen clouds have revealed that the Milky Way is a spiral galaxy.\nOur solar system is thus situated within the outer regions of this galaxy, well within the disk and only about 20 light years "above" the equatorial symmetry plane (to the direction of the Galactic North Pole, see below), but about 28,000 light years from the Galactic Center.

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.

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:)

i don't know about bigger but yeah they found another solar system

The asteroid belt is between Mars and Jupiter and is a huge belt composed mainly from rocks and ice, it's about 6 AU (Astronomical Units) in size, 1 AU is the distance from the Sun to the Earth or 87,000,000 Kilometers..☺

the "smart kid" is incorrect about the size of the sun.  It is only 109 times larger than the planet earth.  The Sun's diameter is 864,938 miles (1,391,980 km). This is almost 10 times larger than the planet Jupiter and about 109 times as big as the Earth. The volume of the Sun is 1,299,400 times bigger than the volume of the Earth; about 1,300,000 Earths could fit inside the Sun.
