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 magnetosphere is defined by the extent of Earth's magnetic field in space or geospace. It extends above the ionosphere , several tens of thousands of kilometres into space , protecting Earth from the charged particles of the solar wind and cosmic rays that would otherwise strip away the upper atmosphere, including the ozone layer that ...
Schematic of Earth's magnetosphere, showing the relative position of the magnetosheath. Scientific research into the exact nature of the magnetosheath has been limited due to a longstanding misconception that it was a byproduct of the bow shock/magnetopause interaction and had no inherently important properties of its own.
The magnetic field of a magnetic dipole has an inverse cubic dependence in distance, so its order of magnitude at the earth surface can be approximated by multiplying the above result with (R outer core ⁄ R Earth) 3 = (2890 ⁄ 6370) 3 = 0.093 , giving 2.5×10 −5 Tesla, not far from the measured value of 3×10 −5 Tesla at the equator.
These ejections can collide with Earth’s magnetosphere, the barrier protecting humanity from the harshest impacts of space weather, to produce geomagnetic storms. More geomagnetic storms may ...
The interaction between the CME and Earth's magnetic field, or magnetosphere, creates ribbons of light in the far northern skies that glow green, pink and other colors.
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.
“The magnetosphere Voyager 2 measured was only a snapshot in time. “This new work explains some of the apparent contradictions, and it will change our view of Uranus once again.”
