- Jupiter's iconic “Great Red Spot” is a massive storm larger than Earth.
- The Red Spot has raged for over 350 years — maybe longer!
- Winds in the Great Red Spot can reach 432 km/h (268 mph).
- Jupiter has at least 95 known moons.
- The four largest moons are called the Galilean moons.
- Galileo Galilei discovered the Galilean moons in 1610.
- Jupiter’s largest moon, Ganymede, is bigger than Mercury.
- Ganymede is the largest moon in the solar system.
- Europa, another moon, may have a subsurface ocean beneath its icy crust.
- Europa is considered a prime candidate for alien life.
- Callisto, one of Jupiter’s moons, is one of the most heavily cratered bodies in the solar system.
- Io, another moon, is the most volcanically active body in the solar system.
- Io’s volcanoes can shoot lava hundreds of kilometers high.
- Jupiter has a faint ring system made of dust.
- Its rings are much fainter than Saturn’s.
- Jupiter rotates extremely fast — one rotation takes about 10 hours.
- This fast spin gives Jupiter a noticeable equatorial bulge.
- Jupiter has the shortest day of any planet in the solar system.
- It takes Jupiter about 12 Earth years to orbit the Sun.
- Jupiter’s gravity is 2.5 times stronger than Earth’s.
- A 100 kg person would weigh 253 kg on Jupiter!
- Jupiter’s magnetosphere is the strongest of any planet.
- Its magnetic field is 20,000 times stronger than Earth’s.
- Jupiter has powerful auroras at its poles.
- NASA’s Juno spacecraft is currently studying Jupiter.
- Juno has provided stunning images of Jupiter’s cloud tops.
- Jupiter emits more heat than it receives from the Sun.
- This excess heat comes from gravitational contraction.
- Jupiter was likely the first planet to form in our solar system.
- It may have played a role in protecting inner planets from asteroid impacts.
- Some scientists think Jupiter once had a solid core.
- Its current core is likely a dense, fuzzy mix of rock and metal.
- Jupiter has bands of clouds moving in opposite directions.
- These bands create storms at their boundaries.
- The white and brown bands are made of ammonia crystals.
- Lightning on Jupiter can be 10 times stronger than on Earth.
- Its cloud layers include ammonia, ammonium hydrosulfide, and water.
- Jupiter's “zones” are light bands, and “belts” are dark ones.
- It was the first planet imaged by a space probe — Pioneer 10 in 1973.
- Voyager 1 and 2 sent back iconic images of Jupiter in 1979.
- The Galileo spacecraft orbited Jupiter from 1995 to 2003.
- Jupiter’s moons may have more water than all of Earth’s oceans combined.
- Some of its moons are thought to have subsurface saltwater oceans.
- Jupiter’s gravitational pull captures comets and asteroids.
- It played a key role in the impact of Comet Shoemaker-Levy 9 in 1994.
- The impact left Earth-sized scars on Jupiter's surface.
- Jupiter can sometimes be seen with the naked eye.
- It’s often the fourth brightest object in the night sky.
- Jupiter inspired myths in many cultures.
- Its name in Greek mythology is Zeus.
- In Hindu mythology, Jupiter is associated with the guru planet Brihaspati.
- Jupiter’s atmosphere contains trace amounts of methane and water vapor.
- It has a slight flattening at the poles due to its rapid rotation.
- Jupiter has multiple jet streams flowing at different latitudes.
- Storms on Jupiter can last for years or even centuries.
- Jupiter’s immense pressure crushes anything that tries to go too deep.
- It has been studied for over 400 years since Galileo's time.
- Juno's mission is expected to last until at least 2025.
- Scientists believe Jupiter's magnetic field influences its moons’ geology.
- Jupiter's mass makes up 70% of the planetary mass in the solar system.
- Jupiter has a very thin ring system, mostly made of dust from moons.
- The moons Metis, Adrastea, Amalthea, and Thebe contribute to its rings.
- Jupiter helps shape the asteroid belt’s outer edge.
- Some of its moons are captured asteroids.
- Jupiter’s trojan asteroids share its orbit around the Sun.
- More than 10 spacecraft have flown by or studied Jupiter.
- Jupiter has a subtle glow in infrared due to heat emission.
- In the early solar system, Jupiter may have migrated from its birth orbit.
- Jupiter is often used as a model to study gas giants in other systems.
- It’s a common reference point in the search for exoplanets.
- Jupiter’s atmosphere has storms called “brown barges.”
- Some of its smaller storms form and disappear in just a few days.
- Jupiter has “hot spots” — clear regions in its clouds.
- Its magnetic field traps radiation, creating dangerous radiation belts.
- Jupiter’s northern and southern hemispheres are not symmetrical.
- “Jupiter’s heartbeat” refers to oscillations seen in the planet’s magnetosphere.
- The planet’s radio emissions can be detected from Earth.
- Jupiter's moons may be colonization candidates in the far future.
- It is the best natural “vacuum cleaner” for the solar system — absorbing comets.
- Jupiter’s density is only 1.33 g/cm³ — just slightly denser than water.
- If it were just 80 times more massive, Jupiter could have become a star.
- Jupiter reflects about 52% of the sunlight it receives.
- Jupiter’s magnetosphere is so large it could fit the Moon’s orbit inside it.
- Its core may be 20 times Earth’s mass but is still a mystery.
- Jupiter has a powerful radiation environment that can fry spacecraft electronics.
- Juno's special orbit helps it avoid Jupiter’s most intense radiation zones.
- The Juno spacecraft rotates like a spinning top for stability.
- Jupiter continues to surprise scientists with every new mission.
- Even after centuries of study, we’ve only just begun to understand this giant world!
- Jupiter has cyclones at both poles that are arranged in geometric patterns, including pentagons and octagons.
- The planet’s auroras are powered not just by the Sun, but also by the volcanic activity of its moon Io.
- Some of Jupiter’s small moons have retrograde orbits, meaning they orbit in the opposite direction of the planet’s rotation.
- Jupiter was the first planet beyond Earth ever visited by a spacecraft — Pioneer 10 in 1973.
