1) While the black hole itself isn't radiating out much (Hawking radiation), any accretion disk would. Radiation being emitted by, even a vestigial accretion disk, would fry the neighborhood. 2) Where is the habitable zone around a black hole? There would not be any, is my guess. So: frozen Earth. 3) Comets and asteroids falling in the black hole (after all, would energize the accretion disk: more frying. 4) Black holes don't "suck" matter/energy. They fall in when matter/energy cross the event horizon. So, no, II am rather confident no habitable (as we understand "habitable") planet orbits a black hole, dormant or not, of any size.

hmmm.... ok, I understand the difference. I guess zero gravity is not experienced anywhere in the universe then. I can't come up with any location in the entire universe where there is pure "zero gravity."
