There are only enough planets and ships for 5 players, however this can be remedied. Use something simple for the planets, 5 objects of some type, then use 20 coins or buttons, cubes, something small, for the ships.The main problem you'll run into is the destiny deck. There are only 5 colors in the deck, but there are 3 "special destiny" cards. You can use those to represent your 6th player, and then not have the special destinies.
I will mention that if you buy any of the expansions, you get everything you need for a 6 player game, but I know that comes with an extra price tag.
Hope this helps.
