Not impossible, just very difficult, and I shouldn't happen naturally
:-)
Anything can be made into a black hole if you squeeze it hard enough -
however, small ones don't last very long ;-)

Wandering off at a slight tangent, an old friend of mine proposed a
fictional hyperdrive where the safe 'jump' points were at the Lagrange
points (specifically the L4 & L5 ones) of a planet's (or moon's) orbit.

So, they'd be close in, but in a predictable position.
