Jupiter barrier
# Jupiter barrier

The Jupiter barrier is the name for the region of the Solar System where the gravitational influence of Jupiter on passing interstellar and in-system objects such as asteroids and comets attracts those objects to the planet where they are either captured in its orbit or destroyed through impacting the planet. Because of this barrier, Jupiter has been nicknamed the Solar System's "cosmic vacuum cleaner" by astronomers, who have also speculated that the barrier reduces the likelihood of such objects from reaching the inner Solar System with potentially fatal consequences on the smaller planets in the inner Solar System such as nearly, if not completely, destroying all life on Earth.
