I think we don't know anymore what's going on with Richard. I believe he would consume Earth almost instantly, including all satellites and maybe the moon.
Didn't do the math myself, but internet says 1 G would be at about 48 km radius.
The selective attraction exerted on the cat by the Richard black hole reveals that Richard is allergic to cats, as cats are attracted to people allergic to them [1].

The cat had the zoomies, was running toward Richard, got spooked, turned to run away digging their carpet destroying knife hands into the carpet, and this is the still shot of them primed to reach escape velocity going away from Richard
I think they're implying that a black hole the mass of a person has the same gravitational attraction that the person had before collapsing (negligible).
Hard to be completely sure.. but an earth mass black hole is roughly an inch across.
That's probably a Jupiter mass black hole.. things would be a lot more wild at that party.
Honestly this is an event horizon.. not the black hole itself and I'm too fucking lazy to do the schwazchild calculations maybe it matters at this scale.. maybe not.
