placement in space: where are the off-world homeworlds?

[Mamorien]

Update: I took the habitability data on Myrr and Nea!son^ma from IST1 and ran it through the world-building steps in chapters 4 and 5 of Fourth Edition GURPS Space, plugging Epsilon Eridani's characteristics (mass, luminosity and so on) into the "Advanced Worldbuilding" portion of the process, and worked out that Myrr has to be orbiting at about 0.54 AU to have the stated temperatures. Also, Nea!son^ma's primary is probably a young G1, unless it's in NGC 6633 (the odd man out in terms of distance -- 375 pc actually equates to around 1200ly -- but in the right direction and old enough to support older stars), in which case it's probably a G4 which Nea!son^ma orbits at 0.88 AU.
