I have no idea, but that sounds pretty wild that they found one only a few km wide! It's interesting to think about the consequences of even being near a black hole the size of a penny. It'd be chaos if it were nearby.
Not as far as I understood, no. Black holes do not suddenly start sucking all matter into them; they have the same gravity as the stars from which they resulted from.
If you compress a penny down to a black hole, it will still have the same mass and the same gravitational pull as the penny had before. (i.e.: not very much)
Oh wow, I didn't know that. I figured it would do exactly what you said it wouldn't, that it'd start sucking everything up. Interesting! Thanks for letting me know!

Thanks, that was a nice read! Fifteen miles across is tiny when you think of black holes.
