That is true, the observable Universe is only about 29 gigaparsecs in diameter (94,585,362,366 light-years). The currently known types of planets could just be several out of hundreds, so you can't categorize a planet as a Gas Giant when it may in fact be an unknown planet type.

Or you could argue that the GoF Universe is different from ours, and therefore our planet types don't apply in GoF.
