Jupiter is the largest planet in our solar system and is known as a gas giant. ¹⁾

It is named after the Roman king of the gods. ²⁾

Jupiter has a diameter of about 86,881 miles (139,822 kilometers), which is more than 11 times the diameter of Earth. ³⁾

The planet has the shortest day of any planet in the solar system, with one day lasting only 9 hours and 56 minutes. ⁴⁾

Jupiter has a very strong magnetic field, 14 times stronger than Earth's. ⁵⁾

It has at least 79 moons, the four largest of which are called the Galilean moons: Io, Europa, Ganymede, and Callisto. ⁶⁾

Jupiter's atmosphere is made up mostly of hydrogen and helium, with traces of other gases like methane, ammonia, and water vapor. ⁷⁾

The Great Red Spot, a giant storm on Jupiter's surface, has been raging for at least 400 years and is larger than the size of Earth. ⁸⁾

The first spacecraft to visit Jupiter was Pioneer 10 in 1973. ⁹⁾

The Juno spacecraft has been studying Jupiter since 2016 and has discovered new information about the planet's structure and magnetic field. ¹⁰⁾

Jupiter has a very faint ring system, discovered in 1979 by the Voyager 1 spacecraft. ¹¹⁾

The pressure at Jupiter's core is so intense that the hydrogen gas there is squeezed into a liquid metallic state. ¹²⁾

Jupiter's atmosphere is responsible for producing some of the most powerful lightning in the solar system. ¹³⁾

It takes Jupiter about 12 Earth years to orbit the sun once. ¹⁴⁾

Jupiter's mass is so large that it actually affects the orbits of other planets in our solar system, particularly the inner rocky planets like Earth. ¹⁵⁾
