What is magnetosphere?
Artistic rendition of a magnetosphere. Sizes are not to scale.
The magnetosphere refers to the region of magnetic influence of a celestial body. This varies depending on the size of the body and the magnetism it generates. Earth's magnetosphere is defined by the region in which the motions of charged particles are largely determined by earth's influence. This effect extends out to about 10 earth radii (63,731 km or 39,123 mi). Certain bodies known for their magnetism, such as magnetars, a form of pulsar, have magnetospheres tens of millions of miles wide. Not every astronomical object has a magnetosphere. All planets in the solar system do, except for the possible exception of Pluto.
