The disturbance force can be expressed simply as

$$F_{SR} = -p_{SR}c_{R}A_{\odot}r_{\oplus\odot}$$

where:

$$F_{SR}$$ - Force contributed by the solar radiation pressure $$p_{SR}$$ - Force per unit area exerted by the solar radiation $$c_{R}$$ - Coefficient of reflectivity of the object. $$c_{R}=1$$ for absolute black body and is generally greater than 1 for other cases. Note: $$c_{R}$$ should not be confused with albedo or Reflection coefficient ! $$A_{\odot}$$ - Area of the object exposed to the solar radiation $$r_{\oplus\odot}$$ - radial unit vector between object and the Sun

Radiation pressure depends on optical properties of surface: For opaque bodies, $$C_{R_a}+C_{R_s}+C_{R_d}=1$$.
 * $$C_{R_a}$$ - coefficient of absorption;
 * $$C_{R_s}$$ - coefficient of specular (mirror) reflection;
 * $$C_{R_d}$$ - coefficient of diffuse reflection
