  We present a new family of exact solutions of dissipative fireball
hydrodynamics for arbitrary bulk and shear viscosities. The main property of
these solutions is a spherically symmetric, Hubble flow field. The motivation
of this paper is mostly academic: we apply non-relativistic kinematics for
simplicity and clarity. In this limiting case, the theory is particularly
clear: the non-relativistic Navier-Stokes equations describe the dissipation in
a well-understood manner. From the asymptotic analysis of our new exact
solutions of dissipative fireball hydrodynamics, we could draw a surprising
conclusion: this new class of exact solutions of non-relativistic dissipative
hydrodynamics is asymptotically perfect.
