The earth's magnetic field performs important functions: it protects us, for example, from charged particles from space and enables migratory birds, bees, and other animals to navigate.
That may mean the planet has a magnetic field that protects it in its perilously close orbit.
Earth is protected from a similar fate only by its strong magnetic field, which guides the solar wind around the planet.
Earth's inhabitants are largely protected from cosmic radiation by the planet's atmosphere and magnetic field, but long - term residents of the moon would be exposed to potential cellular and genetic damage without proper shielding.
Radiation levels on the ISS are 100 times greater than on Earth because the station is not protected by the planet's atmosphere and magnetic field.
