sorry, i'm sure this has been asked but i couldn't find the thread again, and search function isn't working for me.

What's the defense of an undefended colony planet? i'm thinking of taking over what seems to be an inactive player. Do you think 12 battle cruisers would be enough? If not how many bc's would it take roughly? and while i'm at it what's the defense of an undefended outpost? i'm going to commit this info to memory this time. thanks! this would be good info for the wiki as well, or maybe i missed it there.
