I'm not an expert but I thought Jupiter is the Roman equivalent of Zeus. The Romans have the same amount of gods that can do the same thing but with different names. Hera's Roman equivalent is Juno.
Zeus Roman counterpart!! god of the sky. Also known as Zeus, he was the king of gods, and the god of sky, weather, law, and fate
Because jupiters the biggest planet therefore the king of gods in greek (Zeus) or the king of gods in roman (Jove) shows there power.
It is the god of Zeus, God of Sky and Storm
Jupiter is named after the god of the sky and storms.
