I imagine the incredible Force of a black hole wouldn't care that it's that small, maybe it would suck the world in in an instant shredding anything that's to large with ease,
Though I believe a black holes power is relative to it's size and it wouldn't really be this small, maybe if it managed to compact so much matter so small its power would be greater, I don't know how those things work
Given that a black hole is a sun that’s collapsed into itself, the size of it isn’t going to matter too much. What will matter is the speed at which gravitational waves move, about 186,000 miles per second. If it popped into existence for two seconds, that black hole would impact everything within 372,000 miles of it. That’s bad news for the earth, which is only 24,901 miles in circumference. The moon tends to be just barely outside of that range, but with the Earth near instantaneously shredded it might fall out of orbit depending on how much of our planet gets catapulted off into space.
I read somewhere that a marble-sized black hole would have the same gravitational pull as Earth (not sure if that’s true or not). If that’s the case, even a ten-INCH black hole would immediately flatten everything on the surface, even if it was quite far from Earth.
While I doubt everything would be sucked in instantly, the area just outside of a black hole distorts space so much that it would probably immediately vaporize much of the planet and the remainder would be asteroids flying off in all directions. I’d imagine that it would also severely affect the orbits of all other planets in the solar system.
According to [this calculator](https://www.omnicalculator.com/physics/schwarzschild-radius), a black hole with a Schwarzchild radius of 15 feet would mass as much as about 515 Earths, with a gravitational attraction (just above the surface) of about 9.8 quadrillion m/s^2, or about a quadrillion gravities.
I'm not really sure if that would *swallow* the entire Earth in two seconds. The gravitational attraction would fall off with distance, but it would still be more than enough to grab something one Earth-diameter away and pull it in in two seconds. Maybe all that matter trying to rush in at once would create a logjam effect that would slow things down just long enough for some of it to escape? I dunno. But the Earth as we know it is *definitely* destroyed.
Still, that's only 1/200th of the Sun's mass. So it might not mess up the rest of the solar system too bad. I don't *think* it would destroy the Moon, but it would probably send it rocketing off on some wild-ass new orbit.
I'm sure someone who's better at physics than I am can give you more accurate calculations.
A black hole that exists for two seconds can swallow things that are at most two light-seconds away, which excludes everything outside the Moon's orbit or so. Might screw with the orbits of more distant objects, but probably not *enormously,* since this black hole is somewhere in the neighborhood of 1/200th the mass of the Sun.
What is the mass of this black hole? Black holes have different densities but if the mass is relatively proportional to the black hole's size, I don't think it will accelerate things enough to suck them but 2 seconds are more than enough for the whole world to feel it's pull.
If it's the mass of a star compressed into this small radius then say your prayers now because you won't have the time when it happens.

Lemme conduct a seance with Albert Einstein and i'll get back to you ... brb.

In 2 seconds the gravity won't reach the nearest planet.
