Space has been reset

so last night the game froze on me will I was farming. I had just clicked the sort button, and my entire computer completely froze. Re-opened Starbound today and while my character and my ship seem the same. Space has been completely reset. Nothing looks remotely familiar, cant find my home planet and all my bookmarks are gone. I dont seem to have access to the outpost. doubt there is a way to fix this but wondering if there is a way to revert to a previous save point.
