We have studied the survivability of realistic satellite galaxies in different orbits around a host galaxy. Beginning with observed surface brightness profiles of a set of eight nearby satellite galaxies, we obtain 3D mass density profiles, assuming axisymmetry. We then place each of these satellites in the potential field of different analytic host galaxies built to span the range of galaxy types, and calculate the orbit evolution and subsequent mass loss due to dynamical friction and tidal stripping. We test various mass ratios of the satellite to the primary, different initial distances for the satellite, together with different orbital eccentricities, as well. In addition to helping us assess whether an observed satellite is a newly-accreted member of a galaxy system and how susceptible it is to disruption, these simulations may help to constrain many proposed scenarios for galaxy evolution, including heating of disks, growth of bulges and halos, hierarchical growth of galaxies, formation of shells, generation of starbursts, bar and spiral structure, origin of globular clusters and the survival of the core fundamental plane parameters.
