Jupiter is a giant among the planets. It is the second-largest body in the solar system after the Sun and the most massive of all the planets. Its visible surface is not solid but the colorful top layer of a deep, thick atmosphere. An extensive family of moons orbits around Jupiter, and a thin faint ring of dust and particles encircles it.

The Great Red Spot
Jupiter's cloudy atmosphere is dominated by storms. The smallest are like Earth's largest hurricanes. The biggest, the Great Red Spot, is bigger than Earth itself. On the left is the shadow of the moon Europa.

Little Red Spot
In late 2005, astronomers witnessed the birth of Jupiter's second red spot, and second-largest storm - about 70% of the size of Earth. It formed between 1998 and 2000 when three white, oval-shaped storms emerged.

Galilean moons
Jupiter's four largest moons are collectively known as the Galilean moons. These spherical bodies made of a mix of rock and ice are worlds in their own right. By contrast, most of the other moons are small and irregular in shape.
