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 ...
Solar System belts are asteroid and comet belts that orbit the Sun in the Solar System in interplanetary space. [1] [2] The Solar System belts' size and placement are mostly a result of the Solar System having four giant planets: Jupiter, Saturn, Uranus and Neptune far from the sun. The giant planets must be in the correct place, not too close ...
The magnetosphere of Jupiter is the largest planetary magnetosphere in the Solar System, extending up to 7,000,000 kilometers (4,300,000 mi) on the dayside and almost to the orbit of Saturn on the nightside. [17] Jupiter's magnetosphere is stronger than Earth's by an order of magnitude, and its magnetic moment is approximately 18,000 times ...

Peak flux for this electron radiation is 10,000 times stronger than the maximum radiation around the Earth. [45] Pioneer 10 passed through the inner radiation belts within 20 R J, receiving an integrated dose of 200,000 rads from electrons and 56,000 rads from protons (in comparison, a whole body dose of 500 rads is fatal to humans).

A period of weeks or months following the belt's disappearance, a white spot forms and erupts dark brownish material which is stretched into a new belt by Jupiter's winds. The belt most recently disappeared in May 2010. [53] Another characteristic of the SEB is a long train of cyclonic disturbances following the Great Red Spot.
Jupiter radiates more heat than it receives through solar radiation, due to the Kelvin–Helmholtz mechanism within its contracting interior. [70]: 30 [71] This process causes Jupiter to shrink by about 1 mm (0.039 in) per year. [72] [73] At the time of its formation, Jupiter was hotter and was about twice its current diameter. [74]
Aurorae on Ganymede—auroral belt shifting may indicate a subsurface saline ocean. The permanent magnetic moment carves a part of space around Ganymede, creating a tiny magnetosphere embedded inside that of Jupiter; it is the only moon in the Solar System known to possess the feature. [95] Its diameter is 4–5 Ganymede radii. [96]
