We study spherically symmetric solutions of massive gravity. In particular, we concentrate on the decoupling limit, for which the Goldstone picture is especially useful. In the case of the spherical symmetry we find the equivalence between the ``standard'' and the Goldstone descriptions. A new Vainshtein-like solution is found. Numerical investigations shows that for some potentials a well-behaved solution exists, the asymptotic behavior of which is given either by the original Vainshtein's or by this new solution. We also discuss solutions of the full system (not in the decoupling limit).
