My childhood plan has been to become rich and famous so that I can then afford to become a space tourist and make a miniature world all of my own... however, it is possible that my dream is in fact impossible thus I pose this question in hope of rescuing myself from potentially wasting several hundreds of millions; if I took with me a sphere of dirt with a bar magnet through its middle to give it a north and south pole, and once in zero gravity gave it a little spin then threw a handful of iron filings at my miniature planet could I possibly create a tiny world with an orbiting ring like Saturn's?
