Abstract
In this paper we provide estimates for mutual distances of periodic solutions for the Newtonian \(N\)-body problem. Our estimates are based on masses, total variations of turning angles for relative positions, and predetermined upper bounds for action values. Explicit formulae will be proved by iterative arguments. We demonstrate some applications to action-minimizing solutions for three- and four-body problems.

ACKNOWLEDGMENTS
(K.C.) It is my great honor and pleasure to contribute to this special issue dedicated to Alain Chenciner on the occasion of his 80th birthday. Alain’s research works greatly inspired my research directions, his constant support and vigorous communications greatly influenced my research career, and his versatility (in languages, caricatures, etc) greatly changed the stereotype about mathematicians (at least among people in my neighborhood). I also thank the RCD editorial team for their invitation. The second author (B.P.) wishes to express his gratitude to Ya-Lun Tsai for his generous support through his grant at the National Science and Technology Council in Taiwan.
