How would you say “return to the stars” in Latin in the form of a command for instance. Does not need to be an aggressive version of the commas, simply a pleading.
For a straightforward translation, assuming you're addressing a single person:
Regredere ad astra.
Go back to the stars.
Regredī is a nice, classic verb for "return" or "go back". Ad astra also shows up in a few other phrases, like ad astra per aspera (to the stars through difficulties), which helps recognizability too.
