ah, okay, well, i guess you should try and see if you can get a few aligned so you can do flyby's, but if we're including moons it may add to the total if you happen to encounter one of the planets moons (unless said planet is Moho, Dres, or Eeloo.) especially at Jool (coughTylocough) if you can get lucky you can encounter a few of Jool's moons. you can also just fire the probe off into a solar orbit and wait, maybe an orbit going below Moho's and around Eeloo's orbit, eventually youll get an encounter with something, and as long as you dont crash into whatever it is your encountering youll encounter another, then another, and another, until you hit something or quit the game
