Giants That Shaped Everything

Jupiter and Saturn are far more than oversized planets:

• Jupiter outweighs all the other planets put together
• The Great Red Spot is a storm wider than Earth
• Saturn's rings span 282,000 km but average only 10 meters thick
• Europa and Enceladus both hide subsurface oceans that could harbor life
• Titan has liquid hydrocarbon lakes on its surface

Jupiter's gravity has acted as a cosmic shield, deflecting dangerous asteroids away from the inner solar system. Without these gas giants, Earth might have been bombarded far more heavily, leaving complex life less time to evolve.
