The sun is about 26,000 light-years from the center of the Milky Way Galaxy, which is about 80,000 to 120,000 light-years across (and less than 7,000 light-years thick). The Planets The nine planets that orbit the sun are (in order from the Sun): Mercury, Venus, Earth, Mars, Jupiter (the biggest planet in our Solar System), Saturn (with large, orbiting rings), Uranus, Neptune, and Pluto (a dwarf planet or plutoid)
How Big is the Solar System?
It should be a unit that will make a good story afterwards like "All the way from the flagpole to the Japanese garden!" Put the Sun ball down, and march away as follows. Leaving aside the entirely distinct natures of the bodies and the orbits, there is a difference in relative sizes: the spaces within the atom are even larger a hundred times larger-than the spaces within the solar system! The distance from the Sun out to Mercury is about 45 Sun-widths

This logistically complicated experiment is a pathfinder: It is teaching us how to build a whole network of launch sites to monitor Earth's atmosphere on continental scales. Automated software maintained by NASA's Meteoroid Environment Office calculates their orbits, velocity, penetration depth in Earth's atmosphere and many other characteristics

Search for Other Earths In an astronomical breakthrough, scientists have begun discovering planet after planet circling around distant stars as the search narrows for a world like our own. When Pluto is near the sun, it has a thin atmosphere, but when Pluto travels to the outer regions of its orbit, the atmosphere freezes and collapses to the planet's surface
The Incredible Design of the Earth and Our Solar System
In fact, nearly all large planets have been found to be closer to their stars than the earth is to the Sun (which would remove all rocky planets in the habitable zone from those systems). If most of the crust of the earth had not been blown away during the formation of the moon, the earth would have no continents, but would be completely covered by water (see The Moon And Plate Tectonics: Why We Are Alone from spacedaily.com)
Solar System Facts: A Guide to Things Orbiting Our Sun
Credit: NASA View full size image The solar system is made up of the sun and everything that orbits around it, including planets, moons, asteroids, comets and meteoroids. Short-period comets that complete their orbits in less than 200 years are thought to originate from the disk-shaped Kuiper Belt, while long-period comets that take more than 200 years to return are thought to come from the spherical Oort Cloud
The Solar System: The Sun, Planets, Dwarf Planets, Moons, Asteroids, Comets, Meteors, Solar System Formation - Windows to the Universe
Solar system formation began billions of years ago, when gases and dust began to come together to form the Sun, planets, and other bodies of the solar system
the Outer Planets The inner planets (those planets that orbit close to the sun) are quite different from the outer planets (those planets that orbit far from the sun). They are mostly huge, mostly gaseous, ringed, and have many moons (again, the exception is Pluto, the dwarf planet, which is small, rocky, and has four moons)
That means you could easily fit all of the planets between the Earth and the moon, although this is strongly advised against as it would wreck Earth pretty quickly.

An Overview of the Solar System, it's alignment and pictures
The eight bodies officially categorized as planets are often further classified in several ways: by composition: terrestrial or rocky planets: Mercury, Venus, Earth, and Mars: The terrestrial planets are composed primarily of rock and metal and have relatively high densities, slow rotation, solid surfaces, no rings and few satellites. With a few exceptions, the planetary satellites orbit in the same sense as the planets and approximately in the plane of the ecliptic but this is not generally true for comets and asteroids

Planet Order from the Sun; Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus and Neptune Our knowledge of our solar system is extensive but it is far from complete. Please visit our Astronomy news section which gives news, notes and general observations, we also have an interactive tour of the solar system (loads in a new window) All planets can be seen with a small telescope or binoculars and private observatories continue to provide useful information
Comets: 3,354 Orbiting spacecraft such as SOHO have raised this tally in recent years by catching the comets as they plunge toward the Sun - and sometimes vaporize. Dwarf Planets: 5 This new class of worlds helps us categorize objects that orbit the Sun but aren't quite the same as the rocky planets and gas giants in our solar system
