Jupiter is the largest planet in the Solar System, with over twice the mass of all other planets combined. It is composed primarily of hydrogen and helium, with bands of clouds swirling in its atmosphere. Below the clouds is a vast ocean of liquid hydrogen, with a dense core many times hotter than the sun's surface. Jupiter has over 60 moons, with the four largest known as the Galilean satellites. Its most iconic feature is the Great Red Spot, a massive storm twice the size of Earth.

2. Jupiter Jupiter is the 5th planet from the sun. It is 778.4 Km from the sun. Jupiter has more than twice the mass of all the other planets put together. Jupiter is the largest, most massive and fastest spinning planet in the Solar System.

3. The giant world of Jupiter is made manly of hydrogen (about 90%) and helium (about 10%) with a central molten rocky core. Tiny amounts of water, carbon dioxide, methane and ammonia are also present in the outermost layer.

4. Surface The surface hydrogen gas are spread out by Jupiter`s fast rotation in to bands of constantly swirling clouds-it takes the planet only ten hours to make one complete rotation. The cloud top temperature is -110°

5. The Interior Below the cloud there is no solid surface. The gas simply merges into a vast ocean of hot, liquid hydrogen. Scientist’s think the planet’s core is a ball of molten rock six times hotter than the surface of the sun.

6. The Great Red Spot Jupiter`s Great Red Spot is it`s most famous feature. It is a tremendous atmospheric storm twice the size of Earth. Turbulent winds circle around the hurricane, making ripples in the clouds. The Spot turns anticlockwise, taking 9 days to rotate.

7. Jupiter`s auroras Jupiter`s auroras that light up the poles, are caused by charged particles spewed out of volcanoes on Io, one of Jupiter`s moons. The particles are sucked into Jupiter`s poles by the planet`s intense magnetic filed.

8. Jupiter has a very faint ring around its equator. It’s made of microscopic dust particles that resemble black smoke. Jupiter`s Ring

9. Jupiter’s moons Jupiter’s massive gravity (2.36 x Earth’s gravity) holds in its power a set of 63 satellites. The four main moons are Io, Europa, Ganymede and Callisto. They are called the Galilean Satellites.

10. Can life exist on Jupiter? No there is no solid surface only traces of water on the surface and no oxygen to support life. The planet is mostly made of hydrogen and helium. The cloud top temperature is -110° C.
