Consider a viscous incompressible flow around a body in article amssymb empty \mathbbR^3 rotating with constant angular velocity ω. Using a coordinate system attached to the body, the problem is reduced to a modified Navier‐Stokes system in a fixed exterior domain. This paper addresses the question of the asymptotic behavior of stationary solutions to the new system as| x|→∞. Under a suitable smallness assumption on the velocity field, u, and the net force on the boundary, N, we prove that the leading term of u is the so‐called Landau solution U, a singular solution of the stationary Navier‐Stokes system in article amssymb empty \mathbbR^3 with external force kωδ0 and decaying as 1/| x|; here article amssymb empty k∈\mathbbR is a suitable constant determined by N and δ0 is the Dirac measure supported in the origin.
