Current best Polaris trade spots:

[Sir-Derp's]

Not sure if every galaxy is the same no matter the seed, but I think it is the same no matter the seed but changes every update, if so; here is the title, in the Polaris System:

Sun: Barbuhara; Planet-Umditho=small smelter and waypoint station. Also; Planet-Eureet 1=orbital mining station.
-Buy iron, silicon, copper, cobalt, gold, neodymium, and xeno substrate, as well as all other ores on planet, and all ores with extra neodymium from the orbital station.

Sun: Naamimosh; Planet-Aiqq= assembly line, sanctuary with warehouse dealer, and medium smelter.
-Buy and sell small and large optical matrix and bridges for massive money, buy ores from waypoint station and medium smelter along the way on the motorbike, have a bed to reset merchant stock every 8 hours.

Hopefully that helps everyone know the fast start up way to getting lots of ores, money, and ammo, after selling sniper rifles to Bertrams on Omicron starter planet at the Polaris Sanctuary.

Names are randomized out, only few exceptions.

But in the Brotherhood of Farr systems i their territory is a polaris trade station one stop and shop type, in the trading sector of FARR territory. and also a brotherhood of Farr stations you can trade at when done with polaris pretty standard in offerings.. each star you go to in brotherhood of farr territory will have a trade sector and the two stations at least if lucky a ore processing type station also and a colonist station.

homeworld system of FARR doesn't have both stations in my game but the other farr territory systems do.
