Jupiter's magnetic field is the strongest and second-largest contiguous structure in the Solar System, generated by eddy currents within the fluid, metallic hydrogen core. The solar wind interacts with the magnetosphere , extending it outward and affecting Jupiter's orbit.
Jupiter has a rock and/or ice core 10–30 times the mass of the Earth, and this core is likely soluble in the gas envelope above, and so primordial in composition. Since the core still exists, the outer envelope must have originally accreted onto a previously existing planetary core. [5]
The bulk of the hydrogen on Jupiter is solid hydrogen. [12] Evidence suggests that Jupiter contains a central dense core. If so, the mass of the core is predicted to be no larger than about 12 M E. The exact mass of the core is uncertain due to the relatively poor knowledge of the behavior of solid hydrogen at very high pressures. [10]
Cut-away illustrations of the interior of the giant planets. Jupiter is shown with a rocky core overlaid by a deep layer of metallic hydrogen. A giant planet is a massive planet and has a thick atmosphere of hydrogen and helium. They may have a condensed "core" of heavier elements, delivered during the formation process. [9]
Juno is also searching for clues about how Jupiter formed, including whether the planet has a rocky core, the amount of water present within the deep atmosphere, and how the mass is distributed within the planet. Juno also studies Jupiter's deep winds, [58] [59] which can reach speeds of 600 km/h. [60] [61]
Jupiter may be best known as the planetary titan of our solar system with a comparatively small red mark — that still dwarfs the entirety of Earth — and rows of striations going from pole to pole.
Jupiter radiation. Jupiter's magnetosphere is a complex structure comprising a bow shock, magnetosheath, magnetopause, magnetotail, magnetodisk, and other components.The magnetic field around Jupiter emanates from a number of different sources, including fluid circulation at the planet's core (the internal field), electrical currents in the plasma surrounding Jupiter and the currents flowing ...
