The popular Jupiter Shield theory proposes that the planet acts like a giant space shield due to its huge mass causing it to suck in or deflect dangerous debris.
However, this shield theory is slowly falling out of favor and one of the leading critics is space expert Kevin Grazier. [Kevin R. Grazier, Ph.D.]
He's published several papers explaining why he thinks Jupiter is a "sniper rather than a shield".
Recently, he's been aiming to prove how this 'sniper-like' process works.
Grazier's extensive work could put the Jupiter Shield theory in jeopardy.
He told Gizmodo: "Actually, I wouldn't say that it's in jeopardy -- I would say that it has been laid to rest.
"Our simulations show that Jupiter is just as likely to send comets at Earth as deflect them away, and we've seen that in the real solar system."

OMG!
She was about to feed the lions, there was a problem with the latch, and, well, there's a new help wanted on Indeed.
That’s more like it.
Turns them into harmless Dingleberries. Heh.
Since he has much more than an inkling, I'll stick with his view.
Are you saying this guy’s for real? If so, this could be scary...
Thank goodness Jupiter has a bad aim.
The orbital position of Jupiter (and Saturn) are on the opposite side of the solar system currently.

The gravitational effects of the planets are certainly variable over time and could be both shield or sniper. We can only hope and pray.
That’s called ‘appeal to authority’ and is an excuse not to think critically for one’s self.
“If a mile-wide asteroid hits the Earth, we’re done. Probably one a half-mile wide (circa 1/8 the mass) would do it.”
1 Mile wide asteroid hits the Yellowstone Caldera!

Just need to elect Bite-Me and it will stop.
Really? You expect anyone that has ever lined up any kinda sights to actually believe that? There's only ONE trajectory to the target. How many trajectories are NOT on the target?
Sounds more like they are grifting to get some Pols kids on their board of trustees at an exorbitant salary of course.
We need more asteroid control laws.
Maybe a Red Spot law to disarm Jupiter before it does it again.
That's why he's a scientist and you're not.
I blame the Commies in Jupiter’s Giant Red Spot.
Vaquero, I’m curious as to why you think Saturn is not also a contributor. Is it because of the distance. Although next in order from Earth, it is still a lot farther out there than Jupiter. (These distances are stunning, really. But, minuscule in the scheme of the universe.)
Batter up!
“Super girl, the early years!” :)
I think that he, Glazier, is correct. The concept that Jupiter acts as a shield is only partially true. Jupiter’s mass does cause objects to be deflected but there are four possibilities:
1. Object is deflected away from the inner solar system (shield).
2. Object is deflected toward the inner solar system (sniper).
3. Object falls into Jupiter’s gravity well and becomes part of Jupiter or the Jovian system (capture, a subset of shield).
4. Object passes far from Jupiter and is relatively unaffected by Jupiter’s mass.
