Jupiter is the largest planet in our solar system, boasting a diameter of about 86,881 miles (139,822 kilometers), making it more massive than all other planets combined.
As a gas giant, Jupiter is primarily composed of hydrogen and helium, with no solid surface. Its thick atmosphere features swirling clouds and fierce storms, including the Great Red Spot.
Jupiter has the strongest magnetic field of any planet in the solar system, 20,000 times stronger than Earth's, influencing its numerous moons and radiation belts.
Jupiter has at least 79 known moons, with the four largest—Io, Europa, Ganymede, and Callisto—collectively known as the Galilean moons, discovered by Galileo in 1610.
The Great Red Spot is a colossal storm larger than Earth, persisting for at least 350 years. It showcases Jupiter's dynamic atmosphere and extreme weather patterns.
Jupiter has the shortest day of all planets, completing a full rotation in just about 10 hours. This rapid spinning causes its equatorial bulge and unique weather systems.
Jupiter lacks a true surface; its gaseous atmosphere gradually transitions into liquid hydrogen and metallic hydrogen at greater depths, making it an intriguing but unapproachable world.
NASA's Juno spacecraft, launched in 2011, has been studying Jupiter since 2016, providing valuable insights into its atmosphere, magnetic field, and potential for hosting life on its moons.
