Trade Station

Trade Stations are treated as planets (have planet cards and have resources/influence) but cannot be landed on. 
A player gains control of a Trade Station by having a Spaceship in its system; at which point they place a control marker on the grey flag symbol to the right of the station on the system tile. If the system is invaded, the player with Spaceships in the system is now the owner and places their own control marker down 
Trade Stations can be refreshed for 2 trade goods
Distant Suns Domain tokens may not be placed on Trade Stations 
Capturing a Trade Station from an opponent does not break a Trade Agreement
