The n-body problem typically refers to the challenge of understanding the motion of a system of multiple material points that attract each other according to Newton's law of gravitation. This is a classic problem in mathematical natural science, with implications that extend far beyond its astronomical applications. Since the inception of celestial mechanics as a discipline, the n-body problem has been at the core of its study. As many celestial mechanics problems have transitioned into the realm of geophysics, the significance of the n-body problem has only grown stronger.
