  We present Log N -- Log S distribution for close-by young isolated neutron
stars. On the basis of this distribution it is shown that the seven ROSAT
isolated neutron stars (if they are young cooling objects) are genetically
related to the Gould Belt. We predict, that there are about few tens
unidentified close-by young isolated neutron stars in the ROSAT All-Sky Survey.
The possibility that these seven peculiar sources contain a neutron star less
massive and more magnetized then in ordinary radiopulsars is also discussed. In
the aftermath of relatively close recent supernova explosions (1 kpc around the
Sun, a few Myrs ago), a few black holes might have been formed, according to
the local initial mass function. We thus discuss the possibility of determining
approximate positions of close-by isolated black holes using data on runaway
stars and simple calculations of binary evolution and disruption.
