Jupiter

Did You Know?
The planet Jupiter is the fifth planet out from the Sun, and is two and a half times more massive than all the other planets in the solar system combined. It is made primarily of gases and is therefore known as a “gas giant”.
It turns on its axis once every 9 hours and 55 minutes. The rapid rotation flattens the planet slightly, giving it an oblate shape.
The Great Red Spot is a huge storm on Jupiter. It has raged for at least 350 years. It is so large that three Earths could fit inside it.
