This book describes Radiation Pressure Force on Non-spherical (Disk-type) Dust Particle for Equivalent Radii Aeff from 0.01 mm to 1.0 mm of Water Ice in Comparison with Magnetite and Silicate Using Discrete Dipole Approximation (DDA) Method. Here we present the time dependence of direct and perturbation forces by the Sun on solid bodies with radii from 0.1 ?m to 100 m in the interplanetary space, caused by the long-scale time variation of solar radiation/solar wind intensities. We found, when the Sun was very young (<0.4 Gyr in age), the solar wind pressure exceeded the solar radiation pressure in the size region of solid bodies of interest. Furthermore, it is shown that the perturbation effect by the solar wind (pseudo-Poynting-Robertson (PR) effect) was dominant in that time, compared with the PR effect by radiation.
