天体运动是力学和理论力学课程的基本内容之一. 本文借助数学软件Mathematica，基于经典力学相关公式和定律，对行星、周期彗星和双星系统的运动做了精确的动态模拟，所得动态效果图形象生动，有助于学习者建立清晰的物理图像，增加对行星、周期彗星和双星系统的直观认识，增进对天体运动规律的深入理解. 本研究通过Mathematica编程将教材上的理论知识可视化，开发了新的物理教学资源，同时也展现了Mathematica软件巨大的物理教学资源开发潜力.

Celestial motion is one of the basic contents of mechanics and theoretical mechanics. With the help of Mathematica software and based on relevant formulas and laws of classical mechanics, in this paper the motions of planets, periodic comets, and binary star systems are accurately and dynamically simulated. The vivid animations obtained in this study are very helpful for learners to establish clear physical images, increase their intuitive knowledge of planets, periodic comets, and binary star systems, and enhance their deep understanding of celestial motion laws. New physics teaching resources by visualizing the theoretical knowledge from textbooks by Mathematica programming is developed in this study. The tremendous potential of Mathematica software to develop physics teaching resources is also demonstrated.
