Jupiter is the fifth planet from our sun and the largest planet in the solar system. Jupiter's stripes and swirls are cold, windy clouds of ammonia and water. The atmosphere is mostly hydrogen and helium, and its iconic Great Red Spot is a giant storm bigger than Earth that has raged for hundreds of years. Jupiter is surrounded by 53 confirmed moons, as well as 16 provisional ones -- for a possible total of 69 moons. Scientists are most interested in the "Galilean satellites" -- the four largest moons discovered by Galileo Galilei in 1610: Europa, Callisto, Ganymede and Io. Jupiter also has three rings, but they are very hard to see and not nearly as intricate as Saturn's.

With a radius of 43,440.7 miles (69,911 km), Jupiter is 11 times wider than Earth. If Earth were the size of a nickel, Jupiter would be about as big as a basketball. From an average distance of 484 million miles (778 million km), Jupiter is 5.2 astronomical units away from the sun. One astronomical unit (abbreviated as AU), is the distance from the sun to Earth. From this distance, it takes sunlight 43 minutes to travel from the sun to Jupiter.
