Magnetosphere

A magnetosphere is a region around an astronomical object, such as a planet. It is the region where charged particles are affected by the object's magnetic field.^[1][2] The magnetosphere of the Sun is called the heliosphere. Ions and electrons of the solar wind are deflected by the heliosphere.

Since a magnetosphere is magnetic, it is invisible. However, the Earth's magnetosphere makes the Aurora. This causes the famous "Northern Lights" that shimmer in the night sky near the North Pole.

The border between magnetospheres is called a magnetopause and includes the bow shock.
