Gravity is just a distortion of space. Yes, black holes are very massive, and thus their gravitational pull is greater than every-day objects, but they don’t “pull” light. Think of it this way: If you place a bowling ball on a trampoline, the trampoline sags. If you were to roll a ball near the bowling ball, it would “orbit” it. From above, it might appear that the bowling ball is “pulling” on the other ball, but it isn’t. The bowling ball is just distorting the plane of the trampoline so that any line of travel the other ball takes will be influenced by it. Black holes are like bowling balls so heavy, that they distort the trampoline so much that, no matter what you do, the second ball always falls into the middle. No matter how hard you roll it, no matter where you roll it, the ball always ends up in the hole created by the bowling ball. The bowling ball isn’t “sucking” the other ball, it’s just distorting space such that it has no other place to go. Light doesn’t have mass, it can’t be “pulled” by gravity. It just travels in straight lines. But when those lines are bent, it travels around bent lines. Black holes are when those lines are bent so much that the light just ends up back where it started. Does that make sense?
Regardless, a black hole that small would have negligible mass and thus would have no effect.
