Jupiter

Jupiter, the largest planet in our solar system, is a giant ball of gas, mainly hydrogen and helium. It's so big that more than 1,300 Earths could fit inside!. Jupiter is also known for its Great Red Spot, a giant storm that has been raging for hundreds of years, and its many moons, including the largest moon in the solar system, Ganymede. 
Here's a closer look at some fun facts about Jupiter:
Size and Composition:
Largest Planet:
Jupiter is the biggest planet in our solar system, dwarfing all the others. 
Gas Giant:
It's primarily made of hydrogen and helium and doesn't have a solid surface. 
No Solid Surface:
The deeper you go into Jupiter, the more it gets compressed and heated, but it's unclear if there's a solid core or just a thick, super-hot, and dense soup. 
Moons and Rings:
Many Moons: Jupiter has over 90 moons, with four large ones called Ganymede, Callisto, Io, and Europa. 
Largest Moon: Ganymede is the largest moon in the entire solar system. 
Thin Rings: Jupiter also has rings, but they're faint and hard to see compared to Saturn's rings. 
Other Interesting Facts:
Great Red Spot: A huge, long-lasting storm that's larger than Earth. 
Shortest Day: Despite its massive size, Jupiter spins the fastest of all the planets, with a day that's less than 10 hours long. 
Third Brightest Object: Jupiter is one of the brightest objects in the night sky, only dimmer than the moon and Venus.
