About this tool
Earth-Moon System is a free online visual effect. 3D Earth-Moon orbital simulation with Earth rotation, Moon orbit, moon phases and starfield. Interactive eye-candy rendered live on your screen. It runs entirely in your browser — no download or sign-up needed.
The entire process is purely front-end animation, drawing the earth and moon based on Canvas, and using trigonometric functions to calculate orbital positions.
After opening the page, it will display a scene of the earth and the moon orbiting each other. The moon orbits the earth and the earth is also rotating slowly. Parameters such as revolution speed, orbit size, and celestial body size can be adjusted.
It is suitable for use as astronomy science popularization, space-themed decoration, or purely appreciating the sports beauty of the earth-moon system. The realization principle is a simplified version of Kepler's orbital equations.
The Earth-Moon system is a visual effect that simulates the Earth and the Moon revolving around each other. It renders celestial motion in real time based on Canvas.
