Jupiter possesses the largest magnetic field of any solar system planet

If visible from Earth Jupiter magnetosphere would appear larger than the Moon

Jupiter's liquid metallic hydrogen interior acts as a giant dynamo, generating a magnetosphere 20,000 times stronger than Earth's magnetic field. Spanning over seven million kilometres towards the Sun, if Jupiter's magnetic envelope were visible to human eyes, it would cover an area larger than the full Moon in night skies.
