Which one are you thinking of? Out of the outpost planets I have, I find Tatooine and Dandoran the hardest - because they have vehicle or troop guard reserves respectively. I have successfully managed to take both at level 9. It's a 50/50 thing though - certainly not guaranteed. I'm level 7 (but a maxed out level 7).
