Jupiter

(largest planet in the solar system)

Jupiter is the largest planet in the solar system. Characteristics:

Jupiter's surface has a surface feature known as the Great Red Spot (GRS), a red region presumed to indicate a storm in its atmosphere's clouds: such a spot was first observed in 1665 and has been continuously monitored since 1830, seemingly a storm that lasts for centuries. Jupiter's moons include Callisto, Europa, Ganymede, and Io (the four known as the Galilean Moons). Since the late 19th century over 70 additional moons have been discovered as well as a ring system.

Jupiter's interior is of interest: it is presumed to be basically fluid, mostly metallic hydrogen, thus conductive, providing the material for a dynamo and magnetic field. Its strong magnetic field creates a substantial radiation belt (analogous to Earth's Van Allen belts) which emit microwave synchrotron radiation, allowing study of the belt, but also blocking microwave observation of the planet, and would significantly damage any space probe that remained in it. Whether Jupiter has a rocky core is of interest: some planet formation theories assume gas giants form around rocky cores, but analysis indicates all the transitions between Jupiter's internal layers are gradual, with no distinct boundaries.

Past and planned space missions to Jupiter include: Voyager, Galileo, Juno, JUICE, Europa Clipper, and Europa Lander.


The term Jupiter is also used to indicate a Jupiter-like extra-solar planet, often qualified, e.g., hot Jupiter.
