The central surface brightness of the dwarf spheroidal satellites of our own Galaxy is found to correlate with their distance from the Galactic Center (RGC). This observational evidence suggests that environmental effects could strongly influence their structure. This suggestion is further supported by a clear-cut correlation linking mu_V (0) to the galactic tidal force, both in a point mass approximation and assuming a logarithmic Galactic potential.
