In the Stokes approximation the photophoretic motion of large solid aerosol spherical particle is described theoretically. By consideration of the motion assumed that average temperature of the particle surface significantly differs from the temperature of gaseous medium. During solution process of gas-dynamic equations analytical expressions for the force and velocity of photophoresis obtained taken into account the dependence of gaseous medium density and viscosity and heat conduction on temperature .
