Wow, that is impressive. Best I ever saw in any kind of sci-fi game was a triple star system. I hope I find Manchester too someday.
The Sorium there is surely in a gas giant and as such not totally worthless as you could use it for fuel harvesters - the best fuel production method in the game. You could find better, but then again maybe not 1 jump from Sol, and it will definitely suffice for the first 100 years or so.
Should you manage to play to around 150-200 years in, then the Gallicite may become very valuable too, as it is by far the rarest resource later on, so even single deposits might be worth it if you never find better.(actually happened to me in my last game) Multi-Millions at 0.4 is pretty good at that point. But only if you really start to need it.
