Jupiter has the largest and most powerful magnetosphere in our solar system. It stretches millions of miles beyond the planet's surface, engulfing its moons and extending far beyond the orbit of Saturn.

Here are some facts about Jupiter's magnetosphere:

* Size: It's about 700 times larger than Earth's magnetosphere.

* Strength: It's about 20,000 times stronger than Earth's magnetic field.

* Source: It's generated by Jupiter's rapid rotation and its metallic hydrogen core.

* Impact: It traps charged particles from the Sun, creating powerful radiation belts that pose a hazard to spacecraft.
