Jupiter is a gas giant, which means it is made mostly of gas, not solid ground.

It is mostly made of hydrogen and helium (like the Sun).

Jupiter has a huge storm called the Great Red Spot.

This storm has been raging for hundreds of years!

It is bigger than Earth!

Jupiter spins very fast—one day lasts only 10 hours.

This makes it the fastest-spinning planet.

Jupiter has over 90 moons!

Some of the biggest are Io, Europa, Ganymede, and Callisto.

Ganymede is the largest moon in the whole solar system!

Jupiter has rings, but they are thin and hard to see.

Jupiter is like a giant protector—its strong gravity can help pull in space rocks that might otherwise hit other planets.
