Some astronomers believe that one reason Earth is habitable is that the gravity of Jupiter does help protect us from some comets. Long-period comets, in particular, enter the solar system from its outer reaches. Jupiter’s gravity is thought to sling most of these fast-moving ice balls out of the solar system before they can get close to Earth. So long-period comets are thought to strike Earth only on very long timescales of millions or tens of millions of years. Without Jupiter nearby, long-period comets would collide with our planet much more frequently

answer is yes … and no. Some astronomers believe that one reason Earth is habitable is that the gravity of Jupiter does help protect us from some comets.

In addition, in recent decades, astronomers have been able to see signs of comets that have crashed into Jupiter. There was Comet Shoemaker-Levy 9 in 1994. And, in 2009, astronomers observed a dark gash in one side of the giant planet, likely caused by a comet.
