A black hole does not pull on nearby matter like a vacuum cleaner. It follows the same law of gravitation as any other object with the same mass. If the Sun were replaced, instantly and without debris, by a black hole of identical mass, the gravitational field at Earth’s distance would stay essentially unchanged.
Earth would keep almost the same orbital radius and period under that central mass. Newtonian gravity and general relativity both tie orbital motion to mass and distance, not to the composition or brightness of the central body. The event horizon of such a black hole would be far inside the current solar radius, so Earth would remain well outside that boundary, continuing its path through space rather than spiraling inward.
