  In 2010 the first planet was discovered around star HD 34445. Recently,
another five planets were announced orbiting the same star. It is a rather
dense multi-planet system with some of its planets having separations of
fractions of an au and minimum masses ranging from Neptune to sub-Jupiter ones.
Given the number of planets and the various uncertainties in their masses and
orbital elements, the HD 34445 planetary system is quite interesting as there
is the potential for mean motion and secular resonances that could render the
outcome of its dynamical evolution and fate an open question. In this paper we
investigate the dynamical stability of the six planet system in order to check
the validity of the orbital solution acquired. This is achieved by a series of
numerical experiments, where the dynamical evolution of the system is tested on
different timescales. We vary the orbital elements and masses of the system
within the error ranges provided. We find that for a large area of the
parameter space we can produce stable configurations and therefore conclude it
is very likely that the HD 34445 planetary system is real. Some discussion
about the potential habitability of the system is also done.
