Jupiter

Jupiter is the fifth planet from the Sun and it is the is the largest planet in the solar system. It is approximately 143,000 kilometers (about 89,000 miles) wide at its equator. Jupiter is so large that all of the other planets in the solar system could fit inside it. More than 1,000 Earths would fit inside Jupiter.
Jupiter is like a star in composition. If Jupiter had been about 80 times more massive, it would have become a star rather than a planet.What is Jupiter? - NASA
==King of the Gods==
Jupiter was the Roman god of the sky, although he was first recognized as a god of storms, thunder and lightning. As time went on, Jupiter became known as a protector of the roman people.
Jupiter was the Roman equivalent to the Greek supreme god, Zeus.
==Atmosphere==
Jupiter is a giant gas planet. Its atmosphere is made up of mostly hydrogen gas and helium gas. The planet's surface is covered in thick red, brown, yellow and white clouds.
One of Jupiter's most famous features is the Great Red Spot. It is a giant spinning storm, resembling a hurricane. At its widest point, the storm is about three-and-a-half times the diameter of Earth. Jupiter is a very windy planet. Winds range from 192 mph to more than 400 mph.
Jupiter rotates, or spins, faster than any other planet. One rotation equals one day. Jupiter's day is only about 10 hours long. Jupiter's orbit is elliptical, or oval-shaped. It takes 12 Earth years for Jupiter to make one revolution around the Sun, so a year on Jupiter is equal to 12 years on Earth.
The temperature in the clouds of Jupiter is about minus 145°C (-234°F). The temperature near the planet's center is much, much hotter. The core temperature may be about 24,000°C (43,000°F).
If a person could stand on the clouds at the top of Jupiter's atmosphere, the force of gravity he or she would feel would be about 2.4 times the force of gravity on the surface of Earth. A person who weighs 100 pounds on Earth would weigh about 240 pounds on Jupiter.
Jupiter has an extremely powerful magnetic field, like a giant magnet. Deep under Jupiter's clouds is a huge ocean of liquid metallic hydrogen. As Jupiter spins, the swirling liquid metal ocean creates the strongest magnetic field in the solar system. At the tops of the clouds (tens of thousands of kilometers above where the field is created), Jupiter's magnetic field is 20 times stronger than the magnetic field on Earth.

The largest of Jupiter's moons is Ganymede. It is the largest moon in the solar system. Ganymede is larger than the planet Mercury and three-fourths the size of Mars. Ganymede is the only moon in the solar system known to have its own magnetic field. Ganymede and Callisto have many craters and appear to be made of ice and rocky material.
Io has many active volcanoes. The volcanoes produce gases containing sulfur. The yellow-orange surface of Io is most likely made of sulfur from the volcanic eruptions. Europa is the smallest of the Galilean satellites. Europa's surface is mostly water ice. Beneath the ice may be an ocean of water or slushy ice. Europa is thought to have twice as much water as Earth.
