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 ...
The plasmasphere, or inner magnetosphere, is a region of the Earth's magnetosphere consisting of low-energy (cool) plasma. It is located above the ionosphere . The outer boundary of the plasmasphere is known as the plasmapause , which is defined by an order of magnitude drop in plasma density.
Artistic representation of Earth's magnetosphere. The plasma sheet is highlighted in yellow. In the magnetosphere, the plasma sheet is a sheet-like region of denser (0.3-0.5 ions/cm 3 versus 0.01-0.02 in the lobes) [citation needed] hot plasma and lower magnetic field located on the magnetotail and near the equatorial plane, between the magnetosphere's north and south lobes.
Diagram of IMAGE spacecraft Launch of IMAGE spacecraft aboard of Delta 277.. IMAGE was the first spacecraft dedicated to imaging the Earth's magnetosphere. [10] IMAGE was a spacecraft developed by the Medium-class Explorer (MIDEX) program, and it was the first spacecraft dedicated to observing the magnetosphere of the Earth, producing comprehensive global images of plasma in the inner ...
The magnetosphere is roughly shaped like a hemisphere on the side facing the Sun, then is drawn out in a long wake on the opposite side. The boundary of this region is called the magnetopause , and some of the particles are able to penetrate the magnetosphere through this region by partial reconnection of the magnetic field lines.
Schematic view of the different current systems which shape the Earth's magnetosphere. Earth's ring current is responsible for shielding the lower latitudes of the Earth from magnetospheric electric fields. It therefore has a large effect on the electrodynamics of geomagnetic storms.

Short video featuring commentary by David Sibeck, project scientist for the THEMIS mission, discussing a visualization of reconnection fronts. A substorm , sometimes referred to as a magnetospheric substorm or an auroral substorm , is a brief disturbance in the Earth's magnetosphere that causes energy to be released from the " tail " of the ...
