terminology clarification (using any of these interchangably is asking for trouble):

• Stations are NPC-controlled entities which offer docking. some are of the kickout variety, i.e. they have such short undock runways that re-docking may be perilous
  • consider making instant-dock & undock bookmarks for stations you frequent
• Structures are one of eight player-owned & operated entities (e.g. Astrahus, Fortizar) which may or may not offer docking and tethering but still have docking radii, beyond which tether breaks
  • if you are AFK on tether, your ship can be bumped off tether and then destroyed. dock up if AFK! deep-tether bookmarks are also useful on structures you frequent
• Player-Owned Starbases aka POS are password-protected enclosed spaces placed at fixed locations by moons
