The Irish founding heritage is an early-arrival cross-corridor exception consistent with Wave 2 prospecting demographics, where individual prospectors of any background followed survey data rather than corridor cultural networks. "Drift" as a modifier is authentic mining vocabulary — the name is functional, which is the characteristic naming pattern of wave_2 extractive settlements. The loop member topology between Ross 154 and GJ 526 gives the system two transit connections without making it a routing hub, which is consistent with a mid-scale extractive system that is important to its immediate neighbors but not to the broader corridor. +## Celestial Bodies + + +| Orbit | ID | Name | Type | Inhabited | Pop | Mass | Gravity | Year (d) | Day (h) | Atmo | Biome | Hydro | Economy | Settlement | Industrial | +|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---| +| 1 | `GJ628b` | — | planet | no | — | terrestrial | 0.30g | 5 | 115.2 | none | barren | — | — | — | — | +| 2 | `GJ628c` | Brennan's Drift | planet | yes | 92K | terrestrial | 0.78g | 18 | 432.0 | standard | temperate_terminator | liquid_water | mining | urban_concentrated | mining_refractories | +| 3 | `GJ628-belt` | — | asteroid_belt | no | — | — | — | — | — | — | — | — | mining | — | — | +| 4 | `GJ628d` | — | planet | no | — | terrestrial | 0.44g | 95 | 21.6 | thin | frozen | — | — | — | — | +| 5 | `GJ628e` | — | gas_giant | no | — | — | — | 380 | 12.4 | gas_giant | — | — | — | — | — | +| ↳ 5.1 | `GJ628e-m1` | — | moon | no | — | dwarf | 0.10g | 5 | 124.8 | — | frozen | — | — | — | — | +| 6 | `GJ628f` | — | planet | no | — | terrestrial | 0.36g | 1200 | 30.4 | trace | frozen | ice | — | — | — | +| 7 | `GJ628g` | — | planet | no | — | terrestrial | 0.27g | 3200 | 38.6 | trace | frozen | ice | — | — | — | +| 8 | `GJ628h` | — | planet | no | — | dwarf | 0.11g | 7400 | 25.8 | none | frozen | ice | — | — | — | +| 9 | `GJ628-oort` | — | oort_cloud | no | — | — | — | — | — | — | — | — | — | — | — | + +### Stations & Facilities + +| ID | Name | Type | Orbits | Population | Economy | Governance | Docking | Gate | Districts | +|---|---|---|---|---|---|---|---|---|---| +| `GJ628-oort-S1` | Brennan's Drift Horizon | horizon | `GJ628-oort` | 620 | transit | — | major | yes | 1 | + ## Topology - **Hop Distance from Gateway:** 4
