Ok, I was thinking you could zoom in to any planet, but it only works the other way around. (You can zoom out to see the entire galaxy from a planet.) I thought a planet was listed as "unexplored" if you hadn't been to it yet. That's the way it is in ME2, and I thought I remembered the same for ME1.
