Jupiter is the biggest object orbiting the Sun.
Jupiter is mainly composed of gases, mostly hydrogen and helium.
In this image, Jupiter's moon Io is the 'bead' just above the Great Red Spot.
The Great Red Spot is bigger than Earth. Studies have indicated that the Great Red Spot is travelling around the planet.
The Great Red Spot is a storm bigger than Earth, and has been seen since Jupiter was first examined through telescopes hundreds of years ago.
It appears to be shrinking.
