"Each planet, while vastly different from one another in almost every respect, is exactly the right size to suit its distance from the Sun so that it is able to maintain a more or less circular ellipse around its governing body—the Sun. The Sun is exactly the right size to exert just enough influence on its orbiting subjugates to keep them bound in a not too confining framework which allows them the freedom to further subjugate their respective moons and rings as they see fit, but keeps them from smashing into each other and bringing the whole system down in a cataclysmic orgasm of hydrogen, carbon and puppies. If the Sun were to be any smaller, the planets would secede from the system and drift to another after smashing through the Oort Cloud like a 95 year-old plowing his Plymouth through a Florida flea market. If it were any larger, they would all be pulled into warm, gooey center, kicking and screaming as they were swallowed up by their hegemonic blast furnace of an overlord.
You can probably see where I'm going with this." ~Dante's Infuego
