We study nonstationary spherically symmetric solutions of the Einstein-scalar field system with a massless scalar field minimally coupled to gravity. We use a method for constructing nonstationary configurations of a spherically symmetric scalar field, based on the separation of one invariant equation written in terms of the characteristic function. The behavior of this function makes it possible to interpret the solution as a black hole, wormhole, or naked singularity. Numerical and exact analytical nonstationary solutions are presented. Special attention is paid to the class of asymptotically flat solutions.
