Curious; the galaxy map does not want to find and zoom in on the "second" one. You can find it by moving the map manually to the co-ordiantes (-374, -97, -459). That's quite remote, if you're just hopping about the bubble - it's 600 LY away from Sol, in the general direction of out past Sothis and the Pleaides. There are plenty of "green systems" much closer to Sol than that. Like Barnard's Star, for example.
