Jupiter is the largest planet in the solar system. It is 365 million miles away from Earth. Jupiter has many unique qualities. Its qualities distinguish it from other planets. Here are some fun facts about Jupiter:
Fun Fact #1
The giant red spot on Jupiter is a persistent storm that is larger than Earth! This is known to have been in existence since 1655.
Fun Fact #2
Jupiter’s rotation is the fastest of all the planets in the Solar System. It completes a full rotation in less than 10 hours.
Fun Fact #3
Jupiter has the biggest moon in the Solar System, Ganymede. It is even bigger than Mercury and Pluto.
Fun Fact #4
In 1994, pieces of a comet called shoemaker-Levy 9 broke apart and crashed into Jupiter. This left patches in Jupiter’s atmosphere that lasted for many months.
Fun Fact #5
Its rings are composed mainly of dust particles ejected from some of Jupiter’s smaller worlds during impacts from incoming comets and asteroids. The ring system begins some 92,000 kilometers above Jupiter’s cloud tops and stretches out to more than 225,000 km from the planet. They are between 2,000 to 12,500 kilometers thick.
Fun Fact #6
It turns on its axis once every 9 hours and 55 minutes. The rapid rotation flattens the planet slightly, giving it an oblate shape.
Fun Fact #7
Jupiter has a liquid metal ocean (metallic hydrogen) at its center, surrounded by thousands of kilometers of hydrogen and helium gas.
Fun Fact #8
Jupiter is the planet with the strongest pull of gravity in the Solar System. If we were able to stand on the surface of Jupiter, we would weigh three times as much as we would weigh on Earth. The only other object in the Solar System with a stronger pull of gravity is the sun.
Fun Fact #9
The mass of Jupiter is 318 times the mass of the Earth. In fact, Jupiter has 2.5 times the mass of all the other planets in the Solar System combined.
Fun Fact #10
That’s right, all those beautiful whirling clouds and storms you see on Jupiter are only about 50 km thick. They’re made of ammonia crystals broken up into two different cloud decks. The darker material is thought to be compounds brought up from deeper inside Jupiter, and then change color in sunlight. But below those clouds, it’s just hydrogen and helium, all the way down.
Fun Fact #11
If you were to descend into Jupiter, the thin, cold atmosphere becomes thicker and hotter, gradually turning into a thick, dark fog. In the blackness about 1000 km down the pressure squeezes the atmosphere so hard that it becomes like liquid.
Fun Fact #12
At the center of Jupiter is a rocky core, slightly bigger than Earth, but weighing about 20 times more.
Fun Fact #13
The giant red spot on Jupiter is one of the planet’s defining traits. It is known to have existed for at least 300 years, and hasn’t shown any signs of dying down. And while it appears small compared to the immense size of its host planet, the storm would swallow the Earth whole without even a second thought.
