  In this paper, analytical solutions describing static and spherically
symmetric sources in the decoupling limit of massive gravity are derived. We
analyze the model parameter range and specify when a Vainshtein mechanism is
possible. Furthermore, we use gravitational lensing and velocity dispersion
data from galaxies to put constraints on the mass scale of the graviton. The
result for the inverse graviton mass scale lambda_g = h/(2pi)/(c m_g), in units
of the Hubble radius r_H=c/H_0, is of the order lambda_g/r_H > 0.01-0.02 at 95%
confidence level.
