If you wanted to place satellites or asteroids in circular orbits such

Orbits would not be stable because of gravitational wave radiation.

ian, why can't you distinguish what you're quoting from what you're
writing? Stability is arbitrary: Make satellites as uniform ring
wedges that circle the hole, eventually locking into place.
