Same with me in 6.xx. The Aquarii System had a secondary star about 25 trillion out, and since the central one was so promising in resources, I decided to purpose build a special craft to go there and back. (the ship design was named "Aquarii Project" to make that clear)
It flew about 9 years to get there and then another 9 back, barely making it on fuel. Sadly the second star did not seed so many resources, but maybe it was for the better. Designing a freighter to get stuff there and back would maybe not have been much economic.
