太阳系行星运动是天文科普中的重要部分，也是了解神秘而美丽的天文现象的重要方式。太阳系行星运动是由太阳的引力作用所决定的复杂而精妙的物理现象，是天文学和宇宙科学研究的核心内容，也是探索宇宙运行规律、认识地球与宇宙关系的关键所在。自古以来，人们夜观星象，对星空产生无限联想，人类的好奇心和探索欲望驱使科技不断进步，衍生出重要的文化价值的同时，重新思考自然世界和人类的关系，为人类提供了研究地球和生命的独特视角。本文通过多维度研究与天文科普、太阳系行星运动相关的天文现象，以直观、生动的设计手法展示行星运动的特点和规律，从而展开以动态海报设计为主体的科普设计实践。在研究过程中采用文献分析法、案例分析法和设计实践等方法，对关于太阳系行星运动的基本物理定律和代表性天文现象的资料进行分析总结，进一步了解太阳系中各行星与地球的产生的影响与基本原理。科普设计注重直观性和趣味性，将太阳系行星的运动规律和数据等由浅入深地通过动态呈现，将简洁的图形语言和太空美学氛围进行结合并进行视觉设计叙事。在设计实践中，通过大量资料与数据的汇总和概括，根据太阳系行星运动中行星数量的不同所产生的不同天文现象进行分类，大致可以分为双星、三星和四星级以上，其中代表性的天文现象可以总结为金星凌日、月掩金星、日全食中的“贝利珠”、土星冲日、金星合木星，以及五星连珠。实践方式以六个系列动态海报的设计形式为主体，搭配科普读物设计、科普衍生设计等设计内容，达到对科普内容从理性到感性的认知。在新媒体快速发展下，动态海报设计在天文科普工作中的灵活性、趣味性应用，对于太阳系行星运动和宇宙奥秘的探索带来更多艺术和设计上的可能。
The motion of the planets in the solar system is an important part of astronomical science and an important way to understand the mysterious and beautiful astronomical phenomena. The motion of the planets in the solar system is a complex and subtle physical phenomenon determined by the gravitational effect of the Sun, which is the core content of astronomy and cosmic science research, and the key to exploring the laws of operation of the universe and understanding the relationship between the Earth and the universe. Since ancient times, people have watched the stars at night and had infinite associations with the starry sky. Human curiosity and desire for exploration have driven science and technology to progress continuously, deriving important cultural values while rethinking the relationship between the natural world and human beings, and providing human beings with a unique perspective on the study of the Earth and life.Planetary motion in the solar system is an important part of astronomical science and an important way to understand the mysterious and beautiful astronomical phenomena. In this paper, we study the astronomical phenomena related to astronomy popularisation and solar system planetary motion through multi-dimensional research, and display the characteristics and laws of planetary motion with intuitive and vivid design techniques, so as to develop the practice of science popularisation design mainly based on dynamic poster design. In the research process, we adopt the methods of literature analysis, case study and design practice to analyse and summarize the basic physical laws and representative astronomical phenomena about the movement of the planets in the solar system, and further understand the influence and basic principles of the planets in the solar system and the Earth. The scientific design focuses on intuitiveness and interest, presenting the laws of motion and data of the planets in the solar system dynamically from shallow to deep, combining simple graphic language and space aesthetics with visual design narratives.In design practice, through the summary and generalisation of a large amount of information and data, different astronomical phenomena are classified according to the different numbers of planets in the planetary motion of the solar system, which can be roughly classified into double stars, three stars and more than four stars, among which the representative astronomical phenomena can be summarised as Venus transits to the sun, lunar occultation of Venus, total solar eclipse of the "Bailey's Pearl", Saturn rushing to the sun, Venus conjunct Jupiter, and five-star streak. The representative astronomical phenomena can be summarised as Venus' transit, Venus' occultation by the Moon, "Bailey's beads" in total solar eclipse, Saturn's solar eclipse, Venus' conjunction with Jupiter, and five-star streak. The practice is based on the design of six series of dynamic posters, together with the design of popular science books and the design of derivatives of popular science, so as to achieve the cognition of popular science content from rationality to sensibility. Under the rapid development of new media, the flexibility and interesting application of dynamic poster design in the popularisation of astronomy brings more artistic and design possibilities for the exploration of the movement of the planets in the solar system and the mysteries of the universe.
