Black holes don't suck things in any more than an equivalent star would.

Popular imagery often shows black holes as cosmic vacuum cleaners pulling in everything nearby. In reality, a black hole’s gravity works exactly like gravity from any other object of the same mass, obeying the same laws that govern planets and stars. If the Sun were somehow replaced by a black hole of identical mass, Earth’s orbit wouldn’t change at all.

What makes black holes different isn’t the strength of their pull from a distance, but how compact they are. Because all that mass is compressed into an infinitesimally small point, you can get much closer to it than you ever could to a star before crossing the event horizon — the boundary past which nothing, not even light, can escape. Objects only get “sucked in” if they stray dangerously close to that boundary; from a safe distance, a black hole’s gravity is nothing unusual.
