From Dragon Ball Encyclopedia, the ''Dragon Ball'' wiki
Planet Jupiter (木星, Moku-sei) is a planet in the North Galaxy.
Planet Jupiter appeared in "Mysterious Yunzabit! The Search for Kami-sama's Spaceship". It was the fifth planet from the Sun in Planet Earth's Solar System, just like its real world counterpart. It was a "gas-giant" and most notable for its "Great Red Spot". The Great Red Spot was referred to by Raiti when the group came upon the tornado on Fake Planet Namek. He stated that the storm never died, just like Jupiter's Great Red Spot. The planet may have had four rings, but in the anime they were presumably hidden or not shown at all.
