Jupiter's magnetosphere is actually larger than Jupiter itself and extends up to 7 million kilometers (4.3 million miles) in the Sun's direction and 2-3 million kilometers (1.2-1.8 million miles) in the opposite direction. If visible, it would appear several times larger than the full Moon in the night sky.
