I just bought the game and went thru the tutorials, but I still cant figure out how to take over a unaccompanied astroid or planet. I get to it, but I dont seem to be able (or know how) to build stuff there to make it mine. I am playing a small map now, researched  the ice planet upgrade and went to the ice planet but I have no clue what to do now that I am there. Like I said I cant seem to figure out how to build something there to make it part of my empire.any help would be great, Thanks.
