Anisotropic <thermal radiation> produces recoil that changes the <semi-major axis> of a rotating solid body. Finite <thermal inertia> provides the temperature lag. Large bodies have small acceleration per unit mass, while very small bodies become nearly isothermal. The <Yarkovsky effect> can supply bodies to dynamical escape regions.
