In this paper we study the stability of the 47 UMa planetary system in the framework of the N-body problem, with application of the MEGNO technique. The method makes it possible to distinguish rapidly between chaotic and regular evolution of a planetary system. Using the initial conditions of the 47 UMa system found by Fischer et al. ([CITE]) we estimate the dynamical bounds on orbital parameters that provide stable motions of the system. We analyze whether a telluric planet can survive orbitally in the habitable zone of the system.
