| 摘要≠ | N-body simulation is a computational method for modeling the dynamics of a system of particles under mutual gravitational forces. Originating from Newton's laws of motion and gravitation, it solves the fundamental equations of celestial mechanics. This technique is essential for understanding planetary orbits, star cluster evolution, and cosmological structure formation. | The Hohmann transfer is a maneuver that transfers a spacecraft between two circular orbits using two impulsive burns (velocity changes). Introduced by German engineer Walter Hohmann in 1925, it is the most fuel-efficient method for coplanar orbital transfers when the transfer time is not severely constrained. The transfer orbit is an ellipse tangent to both the initial and final orbits. |
