Jüpiter, the largest planet in our solar system, is a gas giant primarily composed of hydrogen and helium. It has a strong magnetic field and is known for its Great Red Spot, a massive storm larger than Earth that has been raging for centuries. Jüpiter has at least 79 moons, with the four largest being known as the Galilean moons: Io, Europa, Ganymede, and Callisto. Jüpiter orbits the Sun at an average distance of about 778 million kilometers and takes approximately 12 Earth years to complete one orbit. Its atmosphere features colorful bands and storms, making it a fascinating subject for astronomers. The planet's immense size and gravitational pull influence many objects in the Kuiper Belt and beyond.
