Nah.. they could have put a bigger sign on it or used smaller letters..
Somehow I just think that the name "northern star" was used for it somewhere in the past.. otherwise it wouldn't be around that much. No one calls the OS the Oceanic Star by mistake either.
So it must have had the wrong name.. possibly in the vessel list in the game, or in the editor... or something like that. Too many people use it, so it's not coincidence if you ask me.
