So a bit of necroposting on my part, but how did that adventure end up turning out for you? Because I just found the same system in my game, with the same crazy range to reach.
I'm planing on going there myself, but instead of just sending a survey craft, I'm thinking of shipping a few orbital habitats out there.
Worst comes to worst, they don't end up as great planets, but I still have a couple habitats literally trillions of miles off the beaten path, nice and safe. (Srsly, can't even track that far out with sensors) But I am curious. Could end up with a great little cluster of worlds out there. Go way out there and start building up its own little civilization (might have some trouble, but even asteroid colonies can turn out their own infrastructure after a while, and I'd bring ~50k of it with me, along with assorted minerals, few construction brigades, everything needed to basically start a new civ.
I wonder if over time they'll turn out their own civilian shipping fleet that just goes back and forth around that star.
