I think Ive come up with something that might work. What i was thinking since friday is that the circle in the top represents a top down view of the planet and the circle in the bottom represents the side of the planet. I suspect the relic and orbs to triangulate in such a way with something to give us the coordinates were searching for. because both of these objects are place like the planets orientation on the galactic map.
Here is a image for my explanation.
on the top circle I first thought the zero reference(aka the yellow line in my drawing) to be the axis of movement. however that is for my new theory incorrect and the blue line is this axis of movement for the planet. If i measure the angle between this blue line and the relic. then i get a angle of ~ 31. assuming that the stripes in the ruins mean the area from which the sunlight comes this should then be - ~-31. It also tells us that this side is the negative side.
Looking at the bottom circle the orbs represent the the coordinates on the side. Triangulate the red line with the orb which represents the planet were searching for. then we get a angle of ~29. not knowing what could tell us this side is the negative side but knowing that the new ruins are on the negative side, we can assume this is the negative side.
Also I now think that the pyramid close to the relic represents that there is a moon close to the planet were the ruins are on. For the one in the middle in the top circle which then should be Synuefe XO-P c22-17. The pyramid could tell us that the planet were searching for orbits around a other one and the other 2 are lonely planets without moons.
Ofc the one who pinpointed the objects on that map could have put them slightly in the wrong place.
Then applying this theory to the other planets we get:
Synuefe XO-P c22-17: (~-2,~91)
Synuefe ZL-J d10-119: (~122.5,~-117)
IC 2391 Sector ZE-A d101: (~-12,~5)
of course this theory could be as much as the one next guy. But lets give it a shot!
