An exact analytic solution based on the Kompaneets approximation is found for a shock wave expansion from a point explosion within a preexisting interstellar gas cavity with a power-law gas density distribution. An obvious shock deviation from the spherical symmetry is revealed for the off-center explosion. It is assumed this may give a reason for the complex morphology that is observed in some supernova remnants.
