Jupiter
Discover amazing facts about Jupiter, the largest planet in our solar system and the king of the gas giants
Jupiter's Great Red Spot is a giant storm that has been raging for over 300 years
Jupiter is absolutely massive - it's the largest planet in our solar system and bigger than all the other planets combined! This incredible giant is so big that over 1,300 Earths could fit inside it. Unlike the rocky planets we've learned about, Jupiter is called a "gas giant" because it's made mostly of hydrogen and helium gas, just like the Sun. In fact, if Jupiter had been about 80 times more massive, it could have become a star instead of a planet!
One of Jupiter's most famous features is the Great Red Spot, a giant storm that's been raging for over 300 years. This storm is so big that three Earths could fit inside it! Jupiter also acts like a cosmic vacuum cleaner, using its powerful gravity to pull in asteroids and comets that might otherwise crash into Earth. That's why many scientists call Jupiter our "planetary protector" - it helps keep us safe!
Scientists have been fascinated by Jupiter for centuries, and Galileo was the first person to discover its four largest moons using a telescope in 1610. NASA has sent several spacecraft to study Jupiter, including the Galileo mission that orbited the planet for 8 years and even dropped a probe into Jupiter's atmosphere to study what it's made of.
Currently, NASA's Juno spacecraft is orbiting Jupiter and taking incredible close-up pictures of the giant planet's swirling clouds and storms. Juno is helping us understand how Jupiter formed and what's happening deep inside this gas giant. In the future, NASA plans to send missions to Jupiter's moon Europa, which might have an ocean under its icy surface where life could exist!
