Why Jupiter is so important

Jupiter dominates the outer Solar System because of its great size and strong gravity. It influences many smaller objects and helps shape the wider system around it.

Jupiter is covered by cloud bands in different colors. One of its best-known features is the Great Red Spot, a giant storm that has lasted for a very long time.

Why its moons matter

Jupiter has many moons, including large ones that are worlds in their own right. Studying Jupiter often means studying a whole family of fascinating objects.
