  We consider spherically symmetric black holes with minimally coupled scalar
fields and concentrate our attention on asymptotically flat self-gravitating
configurations having the event horizons located at radii much smaller than
$2m$. We think of such configurations as rigorous mathematical models of the
gravitating objects, surrounded by dark matter, in the centres of normal
galaxies. It turns out that the radius of the event horizon of a scalar field
black hole always less than the Schwarzschild radius of vacuum black hole of
the same mass and can be arbitrary close to zero. In astronomical observations,
a key role in distinguishing between black holes, wormholes, and naked
singularities plays measuring parameters of bound quasiperiodic orbits, in
particular, the shape of an orbit and the angle of precession of its
pericentre. We consider a typical two-parameter family of compact scalar field
black holes and compute numerically the shapes of some bound orbits. We find
that a key feature of bound orbits around a compact black hole is that the
angle between closest pericentre points is either negative or, at least, less
than that for the Schwarzschild black hole of the same mass.
