Map from Earth to Sparta An even closer view of the neighborhood of Sol. The scale of this map is speculation, other than the distance from Sol to 82 Eridani. The tricky part lies in the fact that Alderson jumps are of varying size. Prince Samual's World and Makassar are 12 LY apart and only one jump apart. So I've allowed around 10 to 15 LY to each jump on this map, although this is clearly not going to be always the case.
Green lines represent single jumps.
The usual route from Meiji to Earth involves several jumps and passes by Colby. The stops from Earth to Sparta are explicitly given on GTS 149 . Tanith is on the standard routes from Sparta to Earth and from Sparta to New Washington. Going from Earth to New Washington would take 5 months if it were done via Tanith, but the sources don't say this is necessary, so it could be as short as 3 months if New Washington is in the other direction. As in the previous map, green lines represent single jumps and blue lines are more indirect routes.
