| Reached | - Uncrewed: 438, Giordano Bruno - Crewed: 588, Tsiolkovsky |
| Travel | Wormholes: Hawking Bridge (4,400 m) to Aksijaha (Alpha Lyrae) Vast Horizon (3,800 m) to Ran (Epsilon Eridani) Cycler Routes: several Beamrider connections especially near Hera Hazard Rating: varies by world and polity Visa Restrictions: varies by world and polity Freedom of Movement: varies by world and polity; the outer worlds are fairly restricted, due to Backgrounder secrecy Environmental Requirements: Nova Terra and many orbitals are baseline hu environmentally compatible. Some other colonies will require environment suits. |
