Jupiter is the fifth planet from the Sun and the largest in the Solar System. It is a giant planet with a mass one-thousandth that of the Sun, but two and a half times that of all the other planets in the Solar System combined. Jupiter is a gas giant, along with Saturn. (Uranus and Neptune are ice giants.) Jupiter was known to astronomers of ancient times. Jupiter has 67 natural satellites. The Romans named it after their god Jupiter.
Zeus (Ancient Greek: Ζεύς, Modern Greek: Δίας, Días) was the sky and thunder god in ancient Greek religion, who ruled as king of the gods of Mount Olympus. His name is cognate with the first element of his Roman equivalent Jupiter.
