Magnetosphere
A magnetosphere is a region around a planet where its magnetic field dominates and protects it from charged particles from space, like the solar wind.
TECHNICAL DEFINITION
A magnetosphere is the region of space surrounding an astronomical object (e.g., a planet or star) in which charged particles are controlled by that object's magnetic field, shielding its atmosphere from solar wind and cosmic rays.
BACKGROUND
Outer space, or simply space, is the expanse that exists beyond Earth's atmosphere and between celestial bodies. It contains ultra-low levels of particle densities, constituting a near-perfect vacuum of predominantly hydrogen and helium plasma, permeated by electromagnetic radiation, cosmic rays, neutrinos, magnetic fields and dust. The baseline temperature of outer space, as set by the background radiation from the Big Bang, is 2.7 kelvins.

USAGE NOTE
Earth's magnetosphere protects us from harmful solar radiation.
