The Solar System is much more than a collection of planets, moons, comets, and asteroids. It is our home in the cosmos. The Solar System's only star, which we call the Sun, plays a role in nearly every aspect of our cosmic neighborhood. The 8 planets, including Earth, all revolve around the Sun. No two planets are alike. There are hundreds of moons in our Solar System, many are intriguing worlds waiting to be explored. Comets are Solar System interlopers, bringing information from the very edge of the Solar System. Our Solar System resides in a spiral arm of the Milky Way Galaxy, where our Sun is one among billions of other stars. The search for evidence of life, past and maybe even present, is the study of astrobiology. From Earth to the Solar System (FETTSS) provides a few snapshots of the wonders contained within this unique system, the likes of which we have yet to discover anywhere else in the Universe. credit: NASA source: http://chandra.harvard.edu/resources/animations/solar_system.html
