I was intrigued by this question: Would touching a black hole of a small mass (the mass of an apple) cause you to spiral in and get dead? until several answerers pointed out that a black hole with the mass of an apple would just have the gravitational pull of an apple and so would not be very interesting from a gravitation perspective. (Although it could be interesting in other ways, notably Hawking radiation.)
I felt a bit stupid not thinking of that myself but also realized that subconsciously I (and perhaps the original poster of the original apple question?) was picturing a black hole with the size rather than mass of an apple. So now I'm stuck with the followup question:
What would it be like to have an apple sized black hole somewhere here on earth, and what happens when you get too close to it?
Using the formula's in the accepted answer to the other question (and some fruit statistics I found online) I figured that the apple size black hole would have a mass of roughly 4.5 earth masses, live extremely long (ca 3.5 times the age of the universe) and be extremely cold (close to absolute zero) so that the horror scenario of that answer would not occur. But does that mean that everything round the apple black hole is nice and cozy, or am I being too optimistic?
