      You would need something with the mass of 3 Suns in the space less than the size of Earth to make a stable black hole. The center of the black hole is theoretically infinitely dense but we aren’t sure if it would be in real life. It would be very high density though. Something like that would be relatively small (the radius of Earth, maybe even smaller) but would easily tear up the Earth.
