Solved
The trophy does not unlock: A Galaxy Far Far Away
I fully explored all the planets but the trophy did not unlock for me (ps4)
I think I accidentally solved this: close the game completely (or turn off the console), then use the ship travel to each planet. Don't use the hologram on the ship to check the progress, open the minimap each time when you land on each planet to check your progress, it will show you the true progression.
