Deep dives

Jupiter as Earth's Bodyguard

Jupiter is often referred to as Earth's bodyguard due to its immense gravitational force, which plays a crucial role in protecting Earth from potential asteroid and comet impacts. The planet's strong gravity can pull in these space objects, preventing them from colliding with Earth. For instance, the comet Shoemaker-Levy 9, which could have caused significant damage if it had impacted Earth, was instead captured by Jupiter, demonstrating its protective capabilities. This function has led scientists to believe that Jupiter may serve as a shield against cosmic threats, helping to maintain the safety of life on Earth.
