I'm a genuine proponent of renaming Uranus to "Caelus." It's the only planet (save earth) not named for a Roman god. It's named for a Greek god, and completely breaks the naming convention. Funny word play aside, I'd like to see it renamed Caelus.
Right? Such a cool name! I also would not mind if they renamed earth to Terra, though, to keep the trend. But if we keep Uranus, we should make earth Gaia, so Uranus won't be so lonely as the only Greek in the solar system.
I may, may, be anthropomorphizing our planets a bit
