Also interesting, The Game Lore at Cannon mentions Alec Ryder's two sons, Oberon and Neptune.
I have been playing with the Galaxy Map, entering names. Soonstill is mentioned, and there is a system by that name.
If you put in Oberon, you get Sol. Of course, we know where Neptune is. There are also many of the Greek Gods in the Galaxy, Apollo, Zeus, Artemis, Athena, Detemer, Hephaestus, Hera, Delphi, Poseidon...
This I expected since the Greeks named stars after their gods, but I'm working on a theory of triangulation between them since most of us believe Raxxla to be in the bubble, with a distance which could be reached in a Sidney.
The Dark Wheel is another legend of Elite Dangerous that stretches back to the dim and distant past, perhaps second only to the legendary planet Raxxla in its elusiveness.

Also, The GM is a database connected to the location of all the stars in the galaxy. I try different queries and see what pops up. The Oberon pointing to Sol is just one I have found. Cirag unfortunately does not show up and neither does Raxxla spelled in different ways.
With "no clues" and "its in there and Fdev knows where it is", we should look in every nook and cranny in the game. I even search the "credits" once in a while.
