Great Red Spot
Jupiter is the fifth planet in the Sol system, between the asteroid belt and Saturn. It is a the largest planet in the system, a gas giant with 60 known moons. It's primary feature is a large red spot in the atmosphere, which is actually large storm that had never stopped. It rotates counter to the planet's rotation.
In Roman mythology, Jupiter was the king of the gods, and had power over the sky and thunder, and is often pictured with lightning bolts, which is featured in several of Sailor Jupiter's attacks. Her wreath of oak leaves, which appears in the manga, is also a symbol associated with Jupiter in Roman mythology.
