[ExI] RES: Planets galore!

<BillK> We estimate that there may be up to ~10^5 compact objects in the
 range 10^{-8} -10^{-2} solar mass per main sequence star that are unbound
 to a host star in the Galaxy. We refer to these objects as nomads; in the
 literature a subset of these are sometimes called free-floating or rogue
 planets. Our estimate for the number of Galactic nomads is consistent with
 smooth extrapolation of the mass function of unbound objects above the
 Jupiter-mass scale, the stellar mass density limit, and the metallicity of
 interstellar medium.

This makes perfect sense to me. Considering that a star happens when enough
gas is gathered in a sphere to ignite nuclear fusion, it makes sense that
the amount of failed stars must be bigger than the amount of successful
ones. They just couldn't gather enough gas.
