Have you ever wondered whether a giant asteroid might hit our planet, like the one that may have wiped out the dinosaurs on earth?
The planet Jupiter "is our first line of defense" says Allan Boss, an astrophysicist at the Carnegie Institution of Washington. "It is something like 99.9 percent efficient at throwing dangerous space junk, asteroids, and meteorites back out to interstellar space."
How does that happen?
Jupiter is 318 times heavier than earth. Because of its mass, Jupiter creates a huge gravitational field that acts as a giant cosmic vacuum cleaner, drawing the "junk" that floats into the gravitational field toward it and away from other planets.
Jupiter displayed its protective power six years ago when a monster comet broke into fragments and bombarded the planet Jupiter with more destructive power than all the atomic bombs on earth. Not all space particles get deflected by Jupiter, but living in Jupiter's gravitational field minimizes the destructive forces that enter the earth's atmosphere.
Considering Jupiter's protective role, the ancient Romans unknowingly named the mighty planet well. In Old Latin, Jupiter means "Sky-Father."
