If it is a black hole then won’t the nearest planets get sucked into it?

The main difference between a primordial black hole at about the Earth's mass and a planet at about the Earth's mass is the presumed density of dark matter around it. And I'm guessing there's more hawking radiation coming from the black hole than the planet. But small black holes with the same mass as the Earth have the same sucking power as the Earth since it's the mass that does the sucking.
- dreamcompiler 3y agoIf our sun magically turned into a black hole of the same mass tomorrow, nothing would change on earth or in our solar system, except it would get very dark. Nothing would get "sucked in". We'd all freeze to death in a few days, but the earth would go right on orbiting as if nothing happened. If our moon turned into a black hole of its same mass tomorrow there would be even less of an effect. We'd notice we could no longer see the moon, but we'd still have tides just like before.
