Abstract: This paper is concerned with the planar magnetohydrodynamics with initial data whose behaviors at far fields $x\rightarrow \pm\infty$ are different. Motivated by the relationship between planar magnetohydrodynamics and Navier-Stokes, we can prove that the solutions to the planar magnetohydrodynamics tend time-asymptotically to a viscous contact wave which is constructed from a contact discontinuity solution of the Riemann problem on Euler system. This result is proved by the method of elementary energy estimates.

Keywords:  Planar magnetohydrodynamics, Riemann problem, contact discontinuity, large time behavior, stability.
