,Analytical Non-singularity Perturbation Solutions for Extrapolation of Earth’s Satellite Orbital MoIn the Introduction of this book, we describe that in the Solar System all motions of major planets and asteroids, and motions of natural and artificial satellites (such as Earth’s artificial satellites, the Moon’s satellites, Mars’s satellites, and other orbiting spacecraft) have only one main external force.
