I don't want to overanalyze (wait a minute, thats all we do here) but, are all the planets in the star wars saga the same size and density? Or is there some magical aura that gives all the planets the 'same pull of gravity?' like, FOR EXAMPLE, (note: FOR EXAMPLE) we can pretend that tatooine and coruscant are different sizes. wouldn't the physics be different? They don't seem to be at all.
