Why is Jupiter called Earth’s bodyguard?

This Brains On! episode explores whether Jupiter acts as Earth's protector from asteroid impacts.

However, they also present counterarguments suggesting Jupiter might inadvertently bring some space debris closer to Earth. The podcast features a fictional talk show segment with Earth and Jupiter debating this very topic, highlighting the complexities of this scientific question. Ultimately, the episode concludes that the role of Jupiter in protecting Earth remains uncertain, emphasizing the ongoing nature of scientific inquiry.
