A rendering of the magnetic field lines of the magnetosphere of the Earth. In astronomy and planetary science, a magnetosphere is a region of space surrounding an astronomical object in which charged particles are affected by that object's magnetic field. [1] [2] It is created by a celestial body with an active interior dynamo.
This template should be used to present information on both intrinsic and induced planetary magnetospheres belonging to both Solar System and extrasolar planets. For the parameters see example template on the right.
This diagram uses embedded text that can be easily translated using a text editor. This SVG diagram contains embedded raster graphics . [1] Such images are liable to produce inferior results when scaled to different sizes (as well as possibly being very inefficient in file size).
English: Artist's concept of the Earth's magnetosphere. The rounded, bullet-like shape represents the bow shock as the magnetosphere confronts solar winds. The area represented in gray, between the magnetosphere and the bow shock, is called the magnetosheath, while the magnetopause is the boundary between the magnetosphere and the magnetosheath.
A simulation of a charged particle being deflected from the Earth by the magnetosphere. Thus in the "closed" model of the magnetosphere, the magnetopause boundary between the magnetosphere and the solar wind is outlined by field lines. Not much plasma can cross such a stiff boundary. [1]

Despite its name, the magnetosphere is asymmetric, with the sunward side being about 10 Earth radii out but with the other side stretching out in a magnetotail that extends beyond 200 Earth radii. [28] Sunward of the magnetopause is the bow shock, the area where the solar wind slows abruptly. [27]
The magnetosheath is the region of space between the magnetopause and the bow shock of a planet's magnetosphere.The regularly organized magnetic field generated by the planet becomes weak and irregular in the magnetosheath due to interaction with the incoming solar wind, and is incapable of fully deflecting the highly charged particles.
