(largest planet in the solar system)
Jupiter is the largest planet in the solar system.
Jupiter has a surface feature called the Great Red Spot (GRS),
a visible red region presumed to be a storm in its atmosphere;
such a spot was first observed in 1665 and it has been continuously
monitored since 1830, apparently a storm that lasts for centuries.
Jupiter's moons include
(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. The resulting 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 were to remain 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:
Europa Clipper, and
The term Jupiter is also used to indicate
a Jupiter-like extra-solar planet, often
qualified, e.g., hot Jupiter.
