Heh. Keeping to the 'Cosmic Irony' school of naming colonies, Barrayar would probably be doing quite well. After all, the recent few decades...

I still don’t think many humans would be that into making a Barrayar, though.

Plus I might get into trouble with Ms Bujold if I did name a Terran Colony ‘Barrayar’ or a recognisable facsimile thereof.

…but yeah. As chronicled in the books, the aliens would be looking for it because of what’s implied for the Time of Isolation. [“We can’t let cogniscents suffer like that! Not even Humans…”]

But in my universe, the mechanics are such that every planet has some degree of Isolation before re-entering the Galactic Scene [so as to avoid temporal paradoxes, you know]. This lets me invent as many Planet of the Hats as I want.
