Do we know what these are? It's seems obvious they have something to do with the "closer to the stars", maybe the celestial creatures in the mission. If so, can we assume Tyria is one of these planets or moons? If that is true, there are four or five other planets in the solar system and a dozen or so moons (does something live/hail from them, like the builders of the Eye, humans, the Gods, the Seers?)
Assuming they got the gravity right in motion (obviously not scale) it's certainly a complicated, chaotic system, like something out of Firefly.
