Solidad is the starting planet in Andromeda Heart. No defending fleets. A hot jungle planet dense with life.
With fewer exploitable resource types here and later planets you will need to ship resources in from the Perseus Arm including uranium and methane early on but especially hydrogen.
Its default gate destination makes Solidad a natural hub planet. However its other than central position in trade lanes may make it more convenient to move your hub to Seal of War or Seal of Death.
