I've been working in /r/worldbuilding on a science fantasy project that involves Anglo-Saxon mythos. However I've finished working on my main world and am trying to working out the history of the actual humans and how they got to that planet. But i realized I don't have accurate names for prominent stars or the different planets in our solar system.

Do we have a record of what they called them or are they lost to history because Google didn't answer too many things for me.
