  Considering probability distribution as a function of the average density
$\bar{\rho}$ computed for 424 extrasolar planets we identify three log-normal
Gaussian population components. The two most populous components at
$\bar{\rho}\simeq0.7$ g/cc and $\bar{\rho}\simeq7$ g/cc are the ice/gas giants
and iron/rock super-Earths, respectively. A third component at
$\bar{\rho}\simeq30$ g/cc is consistent with brown dwarfs, i.e., electron
degeneracy supported objects. We note presence of several extreme density
planetary objects.
