The present paper is concerned with the existence of radially symmetric stationary solutions for exterior problems in $\mathbb{R}^n (n \geq 2)$ to the compressible Navier–Stokes equation, describing the motion of viscous barotropic gas without external forces, where boundary and far field data are prescribed. For both inflow and outflow problems, the existence of a unique radially stationary solution is shown in a suitably small neighborhood of the far field state. The estimates of algebraic decay rate toward the far field state are also obtained. Furthermore, it is shown that the boundary layer of the density appears as the velocity data tend to zero in the inflow problem, but not in the outflow problem.
