    Introduction

    Jupiter is the largest planet in our solar system with a diameter of 139,822 km. Named after the King of gods it is the 5th planet from the sun and the first of the Gas Giants. Jupiter is made up mainly of gas (90% hydrogen & 10% helium) meaning it does not have a solid surface, under its atmosphere there is a liquid ocean of water and hydrogen. Jupiter has four sets of rings, the halo ring, the main ring, the Amalthea gossamer ring and the Thebe gossamer ring, these are also referred to as the Jovian ring system. These rings are made up of dust particles. Jupiter is known for its great red spot, this spot is a storm that has lasted for over 300 years. Jupiter has a huge magnetic field stronger than any other planet in our solar system. It also has 67 moons, over 50 of these are known moons with a further 17 awaiting confirmation of discovery. The four largest moons are Io, Europa, Ganymede and Callisto and are called the Galilean satellites.
