The fifth planet in our solar system Jupiter a gas giant is actually a small star in composition as it consists mostly of hydrogen and helium just like the sun. But the size and mass is too small for hydrogen fusion, but still the largest planet in our solar system. The Romans named the planet after the Roman god Jupiter.

Jupiter has a very powerful magnetic field and spins at an amazing speed of one revolution in just 9.9 hours. It also have several moons orbiting the planet.

Jupiter's appearance is a tapestry of colorful cloud bands and spots. Great Red Spot is a gigantic storm (bigger than Earth) that has been raging for hundreds of years.

Jupiter is thought to consist of a dense core with a mixture of elements, a surrounding layer of liquid metallic hydrogen with some helium, and an outer layer predominantly of molecular hydrogen
